The German Rollei Company is the originator of the 120 twin-lens reflex camera. Most of the earliest professional cameras used by Chinese photojournalists were of the Rollei brand. Although it is not as fast and light as the ordinary 135 camera, its high-quality image quality has preserved countless historical moments for us.
Rollei - Brand Introduction
Paul Frank and Reinhold Heidecker, the founders of Rollei, were close friends when they were young. They are very fond of optics and mechanics, have a very high level of professional knowledge, and have the same interest and vision in business management. Of course, they did not have the ability to predict the future and could not predict at that time that their company would enjoy such a high international reputation 80 years later and that Rollei cameras would be spread all over the world and be so popular. But one thing is certain, that is the "Rollei Spirit" created by Frank and Heidecker for the company, which laid a solid ideological foundation for Rollei Optical Technology Company's 80 years of brilliant performance in the 20th century.
Rollei - the birth of the company
In 1920, Frank and Dirk jointly founded Franke & Heidecke, which is now quite authoritative in the field of international camera manufacturing. Rollei Optical Technologies, Inc. From selecting a factory site, purchasing equipment, hiring technical personnel, to designing and launching the first camera product, they all considered it very carefully and carefully, negotiated unanimously, and fully listened to the opinions of experts. For a period of time, they went to other cities in Germany or abroad to conduct market research, recruit talents, and learn about international camera manufacturing, either together or separately. Excellent qualities of foresight and composure. Under their organization and command, after 16 months of hard work in the factory construction phase, a large-scale Rollei factory with 450 people was finally successfully completed and put into production smoothly. Since then, another powerful company manufacturing precision cameras has been added to the world's camera manufacturing list.
Both Frank and Heidecker are meticulous, orderly and conscientious people in their work. They both have extremely rigorous and serious characters. From the very beginning of building the factory, they demanded that the factory be built into the best in Germany, requiring technicians and workers to not allow "millimeter errors" in every brick laid and every steel beam framed. Before putting into production, they required every employee to firmly establish the idea of ??"responsible for every screw" and implement it in every link of production. After it was put into production, Frank and Heidecker immediately announced to the outside world that "first-class quality, first-class service" is the business purpose of Rollei Company and requested strict requirements and supervision from peers and users. Over the decades, Rollei's leaders have changed from generation to generation, but their business purpose has not changed at all.
Rollei-Environmentally Friendly Factory
When the factory was first built, Frank and Heidecker planned to build the factory in a garden. During the construction process, they asked architects to specialize in the factory. Design and build pavilions for people to rest, and ask greening workers to plant trees, flowers, and turf around the factory to beautify the environment. The "factory is a garden" plan advocated by Frank and Heidecker was fully realized in 1936. At the same time, they not only pay attention to the environmental construction of the factory area, but also attach great importance to the environmental protection work in the workshop. The workshop is designed to be spacious and bright, with soft and moderate light. High-power exhaust fans and large ceiling fans are installed in each workshop to keep the air fresh and circulated. The machine tools and other equipment in the factory are arranged in an orderly manner, and all the tools and spare parts are arranged as neatly as soldiers waiting for inspection. The sewage after metal coating is treated with special sewage pipes and equipment, and even the bathrooms used by the workers are designed to be comfortable and practical. Rollei also spends a lot of money to hire environmental experts as consultants, asking them to conduct regular inspections of the factory's environmental protection work and write reports for the factory to study. For all this, the two founders of Rollei Company confidently believed that only under such civilized conditions could the quality of the product reach the first level.
Rollei - Initial Products
In 1921, the Rollei Company began to introduce their product to the market - the "Heidoscope" 45/107 stereo multi-lens reflex camera. At that time, Rollei became an international company specializing in the development, development and production of multi-lens reflex cameras. Its products only had two cameras: "Heidoscope" and "Rolleidoscope". The cameras had good shooting effects, but they were a bit expensive. At the beginning, the market sales were not bad, but gradually slow sales appeared. In 1923, based on market conditions and customer needs, Rollei made improvements to the 45/107 stereo multi-lens reflex camera, and organized optical physics experts and mechanical physics experts to jointly develop new products. In 1929, the Rollei Company finally produced the first Rollei prototype twin-lens reflex camera, which shocked the international photography community at the time. Some people commented that this is a revolution in double-lens reflex cameras.
The prototype 6×6 twin reflex camera is born
1929 was a critical year for the development of Rollei Company. The company's various departments coordinated and cooperated smoothly, and the quality of its products was praised in the international market. In this year, Rollei announced the launch of the Rolleiflex prototype twin-lens reflex camera. Frank and Heidecker applied their advanced design and production experience in stereo multi-lens reflex cameras to the development and production of twin-lens reflex cameras using roll film. This is an amazing initiative. The long-awaited waist-level viewfinder by professional photographers and photography enthusiasts and the long-awaited dream of using roll film in the camera have become a reality on the Rollei prototype twin-lens reflex camera.
Before the debut of the Rollei prototype twin-lens reflex camera, the production of twin-lens reflex cameras still used classical technology. At the end of the 19th century, although many double-lens reflex cameras were widely used in photography practice, most of these cameras had wooden bodies, were heavy and large, had simple operating parts, and had average lenses, especially focusing, which were difficult and expensive. By around 1910, the market for twin-lens reflex cameras was shrinking, and manufacturers began to withdraw production of such cameras. In order to cater to the needs of photographers, Rollei launched a new concept of Rollei prototype twin-lens reflex camera. This kind of camera has a strong and durable metal body. The quality of the lens and shutter is particularly excellent. The camera operating parts are reasonably arranged and easy to use. In particular, the bright waist-level viewfinder is particularly convenient for focusing and taking pictures. Even the most picky photographers at the time were unable to focus on it. After rigorous evaluation of the shooting quality of the Rollei prototype twin-lens reflex camera, everyone unanimously praised it.
The emergence of the Rollei prototype twin-lens reflex camera has once again set off a new wave of popularization and promotion of twin-lens reflex cameras in the camera industry. Many camera manufacturers have used it as a model and imitated the production of Rollei. Mode of twin reflex camera. The focal length of the Rollei prototype twin-lens reflex camera was 75mm, the photographic lens aperture was f/4.5, which was soon changed to f/3.8; the viewfinder lens aperture was f/3.1, the film format was 6×6 cm, and it used 117 film.
Rollei twin-lens reflex cameras have been popular for 50 years in the 20th century and have made great contributions to the development of world photography. The Rolleiflex prototype twin-lens reflex camera can be said to be a landmark product in the development of the camera industry in the 20th century.
The standard Type I 6×6 twin-lens reflex camera was unveiled
The launch of the Rollei prototype 6×6 twin-lens reflex camera caused a sensation in Germany and even the international photography community. It has strong and flexible metal components, a bright waist-level viewfinder, reasonable design, and top-quality Tiansai lenses. All these make professional photographers and enthusiasts love it, especially those engaged in photojournalism, who have a special liking for this model of camera. Many of them have almost become voluntary promoters of Rollei cameras.
The charm of quality has enabled Rollei to receive more and more orders for cameras and business is booming. In order to meet the growing market demand for cameras, the two founders, Frank and Heidecker, decided to expand and renovate the factory and expand production scale. By 1930, the number of employees in the company expanded from more than 400 at the beginning of the factory to more than 800.
The generous salary and good working environment have attracted batches of knowledgeable and experienced optical experts and mechanical manufacturing experts to join Rollei's ranks, further enhancing the camera's research and development capabilities and improving Rollei's reputation. Product popularity and competitiveness in the market. When the reputation of Rollei Company skyrocketed and Rollei cameras appeared all over the world, Frank and Heidecker behaved extremely calmly. They knew clearly that for a company that wanted to succeed, this was just the beginning and the road ahead. It’s still a long time! They were not satisfied with the profits and honors that the prototype cameras brought to the company, and continued to lead their employees to develop new models of twin-lens reflex cameras based on the production of prototype cameras. They were determined to make Rollei cameras famous all over the world.
From 1929 to 1932, the prototype 6×6 twin reflex camera produced by Rollei Company had two specifications: one was 75mm, f/4.5; the other was 75mm f/4.5. /3.8. The viewing lens diameter of both is f/3.1. Both cameras later became highly prized by collectors. Most of the parts of the Rollei prototype double-lens reflex camera were manufactured by skilled workers in strict accordance with the design drawings, using hammers and files to hammer and file them one by one. In the face of a large number of customer orders, this production method obviously cannot keep up. At this time, the new camera is in the intense design stage and will be put into production soon once it is finalized. In order to realize the development blueprint of Rollei's business, Frank and Heidecker focused on their respective work in addition to major business negotiations. Frank spent all day working with experts on the design and development of the "standard" camera, sometimes to the point of forgetting to eat and sleep just to improve a component. Heidegger led the engineering and technical personnel and workers to focus on daily production. In addition, the focus was on the innovation and transformation of the workshop assembly line. The core was the design, production and put into use of standard molds for camera parts. At the same time, the Rollei Company also sent elite troops to some parts of the world to conduct thorough and extensive research on the situation and technical trends of various brands and models of cameras in the market, and to collect in detail users' opinions on Rollei cameras. The business intelligence from these cameras was quickly returned to the headquarters for decision-makers to judge and deploy. In this way, the strong operation and management mechanism has enabled Rollei to gradually become an internationally renowned camera manufacturing company.
1932 was an important year for the Rollei Company. The standard Type I 6×6 twin-lens reflex camera, which had been developed for many years, was finally launched on the market. Its superior performance and ease of use , indeed a great surprise to professionals and enthusiasts. In addition to maintaining the solid metal structure of the original camera, the bright waist-level viewfinder and the excellent Tiansai lens, the Rollei Standard I 6×6 twin-lens reflex camera has a major innovation in the redesign of the film winding device. The film winding device of the prototype camera used a disc drive device, while the standard Type I camera was changed to a rocker film winder. This innovation made it more convenient for photographers to load films. The rocker film winder became the iconic device of Rollei twin-lens reflex cameras. For decades, the rocker film winder has almost become a standard device on other brands of 6×6 double-lens reflex cameras.
Since Rollei introduced its first standard Type I 6×6 twin reflex camera in 1932 to 1934, the country produced two specifications of standard cameras (Type I and Type II). , the only difference between the two is that the maximum aperture of the Type II camera is f/4.5; the maximum aperture of the Type I camera is f/3.8. Other indicators are the same, using 120 film, the same focal length of 75 mm, the Tiansai lens installed, the viewfinder lens aperture is f/3.1, the Converter shutter, the shutter speed T, B, 1-1/300 seconds. In addition, the company launched the standard Type III twin-lens reflex camera in 1938. Compared with Type I and Type II, the main differences were the shutter speed and photographic lens.
Evaluation of Standard Type I 6×6 Twin Reflex Camera
“Excellent craftsmanship, solid overall, easy to focus, sharp lens, easy to carry.” However, they also unanimously pointed out that the price of Rollei's standard Type I 6×6 twin-lens reflex camera is too high for ordinary consumers to afford.
The news that the Rollei Standard Type I 6×6 twin-lens reflex camera was “overpriced” aroused the attention of Frank and Heidecker. What kind of camera can win the market and be suitable for the general public? Will consumers accept it? These issues were discussed repeatedly by the two of them and Rollei experts at the time. Although public opinion at the time believed that the price of standard Type I cameras was too high, the orders received by Rollei Company were still impressive. The envy of other camera companies. After careful analysis and research, the company's decision-makers made the decision: "Continue to produce the standard Type I 6×6 twin-lens reflex camera, and speed up the research and development of a 6×6 twin-lens reflex camera that is both economical and practical." On the day this major decision was made, an "economical" camera development team was also born at Rollei.
Rollei 2.8C camera
Rolleiflex 2.8C camera. It was manufactured by Rollei in Germany in 1953, serial number 1299394. The styling design, processing accuracy, and operability are all excellent. The reasonable combination of round, oval and square parts on the fuselage, the mutual contrast between arcs and straight lines, the spacing of each part, and the balance of hardness and softness and density of the overall design all show Impeccable beauty. Unlike Japanese cameras, the Rollei 2.8C is very well-made and uses high-quality metal brass to make every part of the camera and lens. Especially the 10 embossed trademarks of "ROLLEIFLEX" on the upper side of the fuselage, the equidistant vertical stripes on the large focus button, the oblique circular patterns on the two small gears for adjusting aperture and shutter, and the dot dense pattern on the scroll lock button. , all carefully crafted by hand on metal brass. The above-mentioned components are all plated with a layer of shiny metallic chromium (the commemorative version of the Rollei 2.8F is plated with 24K gold). Set against the all-black body, they appear elegant yet dynamic, solemn and full of texture.
The most fun and playable thing about Rollei 2.8C is that it can be fully manually controlled. The fingers of the left and right hands pass through two small gears to adjust the aperture and shutter exposure combination at the same time. When shooting, you can While monitoring the subject, press the shutter to expose. When the shutter between the lenses operates, the sound is soft and the vibration is minimal. The entire body is light and easy to hold, and it feels great in the hand. What is amazing is that the unique design of 2.8C, as well as the shape and distribution of buttons, not only greatly increase the beauty of the appearance, but also facilitate practical operation, allowing both viewing and practicality to be achieved.
The Cord I 6×6 twin-lens reflex camera is launched
The “economical” camera is named Rolleicord. In fact, it produces “economical” cameras to strengthen the market. The idea of ??competition had gradually taken shape in the minds of Frank and Heidecker before the "Standard Type 1" camera was finalized, and they had many "feasibility" discussions with experts. Of course, this was only an intention and had not yet been formed. The situation of decision. When the intention became a decision, the Rollei "economical" camera development team immediately took action.
How to design a generally accepted "economical" 6×6 double reflex camera. How can this kind of camera maintain the dignified appearance and excellent quality of Rollei cameras? After repeated discussions, especially the analysis of market research, the expert group and two company leaders reached a consensus that "economic The appearance and volume of the "model" camera are similar to the "standard" camera, and the operating performance is closer to that of the "prototype" camera. Soon this important knowledge became the guiding ideology for the design and production of "economical" cameras and was put into practice. In action.
In the process of designing and producing "economical" (hereinafter referred to as "Cod I") cameras, Rollei's experts and engineering technicians took the following three measures to implement the company's The proposed decision to reduce costs, ensure quality, and produce the "Cod Type I" camera:
1. Change the Tiansai f/3.8 (4 elements in 3 groups) lens to f/1:4.5 ( 3 elements in 3 groups) Teota lens. The latter is also designed by the famous Zeiss Jena company. It also uses an inter-lens shutter. The shutter speed ranges from T, B, 1-1/300 seconds due to the relatively small aperture. , manufacturing costs dropped.
Although its optical quality is lower than that of the Tiansai lens, its center focusing effect is very good, and the photos taken with a smaller aperture (f/8-f/11) are very clear. As an economical camera, it still uses lenses from famous optical companies. It can be seen that Rollei does not blindly pursue cost reduction and ignore the quality of the camera. Instead, it still finds ways to maintain the excellent optical quality of the lens while minimizing costs, fully embodying Rollei. The company's tenet of "first-class quality, first-class service".
2. The metal body structure and appearance of the "Standard Type I" camera are basically retained, except that the Heidoskop viewfinder lens diameter in the dual lens is changed from 1:3.1 of the "Standard Type 1" to 1:3.8.
3. The upper crank handle is still changed to disc drive. The aperture and shutter linkage structure is cancelled. The aperture and shutter data are displayed directly on both sides of the photographic lens according to tradition. They are controlled separately by dials and displayed through different windows.
After rigorous destructive testing (especially on the shutter), it has been confirmed that the quality of the "Corder I" camera is relatively good. So it was finalized and put into production, and it met customers on the market in 1933. "Code Type I" maintains the characteristics of Rolleiflex twin-lens reflex cameras: "dignity, solidity, reasonable design of mechanical components, excellent lenses and easy to carry". The photos taken are also durable in terms of focus, layering, contrast and tone. Checked.
The original purpose of producing the "Corder I" camera was to produce an "economical" camera with a lower cost that most people could afford. However, the introduction of the "Corder I" camera did not achieve the expected sales results. The reason is that the stickers on the exterior of the camera are not made of soft leather but brass sheets, which are then stamped into horizontal and vertical shapes. There are alternating grid patterns, and the patterns are blackened and electroplated respectively. Such craftsmanship standards naturally make it difficult to reduce costs. This is probably a design decision-making mistake, probably due to the consideration that economical products should not be too economical. The first batch of "Corder I" cameras failed to attract a large number of consumers. Through calm analysis and lessons learned, the company realized how much economic losses an unrealistic design would cause. From then on, Rollei Company avoided this flashy design when designing and producing "Cod" cameras, and thus won the market and achieved very good sales performance. Rollei - the year of success. Since 1932, the Rollei Company has launched the "standard" Rollei Rollei camera and the "economical" Rollei Code camera. Its exquisite production technology and excellent imaging quality have been deeply loved by the company. Respected by people in the photography industry and the majority of enthusiasts. In this way, it also brings considerable economic benefits to Rollei. In early 1937, the German National Statistics Department announced an economic figure, highlighting that in the past five years, the Rollei Company had produced 200,000 Rollei cameras. This is a very remarkable achievement. Many newspapers wrote articles stating, "This is not only a brilliant economic achievement, but also a great contribution to art, because Rollei cameras have armed a group of talented photographers and many photography enthusiasts." It is produced by Rollei Company While it was flourishing, the Second World War launched by fascism was about to break out. Rollei began to receive requests from the government to produce military supplies, such as telescopes, sights, cameras, medical equipment, microscopes, etc. The cameras could only be sold to neutral countries. At this extraordinary moment, camera production has of course declined, but the design and development of high-quality lenses, improvements in operating mechanical components, etc., and all work related to improving the quality of Rollei cameras have never stopped. For example, the "reshoot device" that can make multiple exposures was considered mature during this extraordinary period. What should also be emphasized here is that Rollei's partners, Zeiss's lens designers are looking for first-class lens glass materials everywhere, year after year, again and again, repeatedly, testing and testing under various conditions. The texture of these glass is what makes the "Plana" lens "impeccable, nothing to say", thus ensuring the optical quality of Rollei cameras.
The period from 1929 when Rollei launched the first "prototype" camera to 1936 was the glorious age of Rollei. Their cameras were world-class, with feedback from all over the world. Information believes that this evaluation of Rollei cameras is realistic and well-deserved. Just when Rollei's career was at its peak, the Second World War finally broke out, and the pace of world camera industry production slowed down, and Rollei was certainly no exception. The dark days finally passed. In 1950, Rollei still had 1,000 employees. In the 1960s, Rollei regained its glory and launched a series of high-quality products. Rollei - Usage in the Chinese Photography Industry There is no evidence as to when the first Rollei camera arrived at the Chinese port. The Rollei camera may have developed a relationship with Chinese photographers in the mid-to-late 1930s. However, the "Rollei craze" began in the 1950s. At that time, a few reporters in the Xinhua News Agency's Photography Department, which had a strong lineup of photojournalists, such as Shi Shaohua, Chen Zhengqing, Zheng Jingkang, Qi Guanshan and Qian Sijie, were equipped with Rollei cameras. Later, they were equipped with Rolleiflex cameras. It's our turn to take advantage. Due to the top quality and superior mechanical properties of its lenses, it quickly became popular in the photojournalism world, and Rollei opened the Chinese market.
According to data, Rollei cameras that have played an important role in my country's photography industry have the following types:
1. f/2.8E type, equipped with Planner Photographic lens and f/2.8 Haima Duma three-element three-group viewfinder lens, focal length 80 mm, range-axis selenium photocell light meter, Companion MXV interlens shutter, shutter speed 1 second - 1/500 second, B door, Selfie delay 10 Second. The shutter and aperture can be easily adjusted with the dial. It can shoot 120 rolls and 12 frames. The frame size is 2.25 inches × 2.25 inches. In addition to being equipped with a quick film winding handle and a shutter lock button, it also has multiple shutter push buttons. It weighs 1,220 grams.
2. f/3.5F type, equipped with Planner photographic lens, f/2.8 Haiduma three-element three-group viewfinder lens, focal length 75mm, range-axis selenium photocell light meter, Companion MXV lens Interval shutter, 1 second - 1/500 second, B door, self-timer delay 10 seconds, shutter and aperture can be adjusted together, shooting 120 rolls of 12 pictures, frame size is 2.25 inches × 2.25 inches, also equipped with a quick film winding handle and shutter lock button And multiple exposure control push button, weight 1220 grams.
3. Rollei T-type 6×6 twin-lens reflex camera, Tiansai F/3.5 lens, focal length 75 mm, Companion MXV lens shutter, 1 second-1/500 second, B door, Self-timer delay is 10 seconds, and the shutter aperture can be linked. The lens is designed and produced by Carl Zeiss. The image is clear and sharp. It has a push button for multiple exposure control. Generally speaking, the accuracy of the Rollei camera light meter is average. The metering coefficient provided is for reference only. The metering dial is large and prominent. , extremely susceptible to breakage and damage due to collision.
4. Rollei telephoto 6×6 twin-lens reflex camera, f/4 Sonnar lens, focal length 135 mm, Cambon MXV interlens shutter, B door, 1 second-1/500 second , self-timer delay of 10 seconds, shutter and aperture linkage adjustment, excellent lens quality, designed and produced by Carl Zeiss Company, when the aperture is opened to f/4, the image is clear, the contrast is moderate, there are multiple exposure control buttons and selenium light Light meter.
5. Rollei Code 6×6 dual-lens reflex camera. This is a popular economical camera made by Rollei. The shutter and aperture are adjusted separately. The film winding uses a disc winding device. Carl. f/3.5 Teota lens produced by Zeiss, lens shutter, 1-1/300 seconds, B light meter. Although this camera is a popular and economical model, the quality of the photos taken with it is of the highest quality. Its mechanical performance is trustworthy and reliable, and the price is acceptable to the majority of photographers. It has a certain market in China. Japan is also very popular.
Although the first batch of "Rollei Code" cameras launched on the market failed because they failed to achieve their goal of minimizing cost, these cameras are unique among Rollei products. , the output was small. As the years passed, foreign collectors regarded it as a "treasure" and also called it "Golden Code". China called this "Code Type I" camera "Huapi Code" It is also a fine item among camera collections.
Rollei - the first SL 66 6×6 SLR camera
The authoritative Rollei Company is produced by the Swedish Hasselblad Company and the Japanese Mamiya Company The 6×6 SLR camera was overwhelming. The founders Frank and Heidecker had passed away successively. The new successor of the company decided to develop a 6×6 SLR camera to compete with the above companies. Finally, in 1973, the SL 66 6×6 SLR camera was put on the market. This model camera was for professionals. High-end camera used.
The SL 66 camera features up to 12 different specifications of lenses to choose from, with focal lengths ranging from 30 mm to 1000 mm, including macro, super wide-angle, wide-angle, standard, telephoto, and super telephoto. and catadioptric lenses. ***Having five focusing screens to choose from is also a major feature of the SL 66 camera. Its bright top-viewing frosted glass waist-level viewfinder and precise eye-level prism viewfinder are highly praised by professionals. The shutter has 11 steps from 1 second to 1/1000 second, with curtain shutter running up and down, as well as B door, and X flash sync is 1/30 second.
The SL 66 SLR camera is equipped with 6 types of film cassettes. There are 6×6 universal 120 and 220 film cassettes, 6×4.5 120 and 220 universal film cassettes, Popola (Polaroid) film cassettes, 6×6 and 6×9 loose leaf film cassettes. The SL 66 camera uses a lens produced by Carl Zeiss. The lens is sharp and has good focusing between the lens and around it. It also has a unique structure: there are bayonet mounts of the same shape and size on the front and rear ends of the lens, which can be freely Remove the lens from the lens mount, then flip it 180 degrees and install the lens to the lens mount. The SL66 medium and short focal length lens can be used to photograph extremely close objects after being reverse-mounted, thus providing great convenience for photographic creation.
The photographic optical axis of the SL 66 SLR camera can be adjusted up and down. This is a unique feature among 6×6 SLR cameras. It can effectively use the depth of field to adjust vertical distortion. Since the connection sizes at the front and rear ends of each lens of the SL 66 are the same and both are bayonet mounts, you only need to equip them with a set of filters and special effects lenses. It is easy to use and does not cost too much. It enhances the close-up function and is beneficial to Artistic photography creation, while eliminating the need for accessories such as close-up adapters or additional close-up bellows. The SL 66 camera has a multiple exposure function, and the camera's film cassette is also very convenient for loading films. Its film supply shaft is located below and the film rewinding shaft is located above. When winding the film, the film passes through the film window from bottom to top, which is very simple and secure. This design is superior to other 6×6 SLR camera film boxes.
The SL 66 camera also has shortcomings. For example, the expansion and contraction of the focusing bellows is supported by one side, and the component is not well stressed during focusing. In addition, the rack that controls the expansion and contraction of the bellows is made of plastic. Made, easy to deform. Another shortcoming is that the structural design of the viewfinder lock button is not stable. If you accidentally pinch the lock button with two fingers, the viewfinder will be taken off, and the camera will slip and fall to the ground. Open the waist-level viewfinder to use the magnification When using a magnifying glass, do not cover the surrounding area. Sunlight will penetrate into the frosted glass from the side gaps, reducing the contrast of the viewing image and affecting accurate focus. Although there are still some areas for improvement in the SL 66 camera, its appearance has still been praised by many professional photographers.
Since then, Rollei has successively launched the SL 66E, SLX6×6 and the 6000 and 6008 SLR cameras produced in recent years. These cameras are all based on the SL 66 camera and have been improved on many used parts. , greatly improving shooting efficiency and effects, such as adding a TTL automatic metering system.
Rollei - related information In January 1921, an influential and appealing monthly magazine in Germany, "Photography Industry", published an eye-catching advertisement on a striking page: "Dear readers, please note that in 1920 Half a year ago, our company announced through the press that our complex factory construction work has been completed. At the beginning of this new year, our factory designed and produced a precision product - 'Heidoscope 45/107 stereo multi-lens reflex camera. When it is about to be put on the market and meet the majority of consumers, our Rollei company guarantees that we, the Rollei people, guarantee that we will treat every camera that leaves the factory with a meticulous work spirit. We fully believe in the intelligence and responsibility of the Rollei people. We Fully capable of making cameras perfect, sincerely Franke and Heidecke, January 1921. "This brief text is actually Franke and Heidecke's commitment to the international photography community and consumers. , is the principle they follow for factory management and production, and it is also the "Rollei Spirit" that Rollei Optical Technology Company has consistently advocated and carried forward in the following decades, and is recognized by the world.
