IT168 Review Since Fujifilm launched the X100 with a very retro appearance in 2010, Fujifilm has made a gorgeous turn and returned to the era it once brought with its X series. It has infinite honor in the digital imaging circle. More than two years have passed, and the X series has gradually grown. At this year's CES2013 exhibition, Fujifilm once again launched an upgraded version of the well-received X10? Fuji X20.

From the appearance point of view, there are almost no changes in the Fuji X20 and Fuji X10, which makes many people, including the editor, slightly disappointed. But after our detailed understanding, we found that under the still retro appearance, the interior of the camera has already been injected with more fresh blood by Fujifilm. I think everyone will definitely ask at this time, where does this camera improve? Is it worthy of the majority of consumers to buy? It happened that the Fuji X20 came to our IT168 evaluation room recently. If you have any questions, we will answer them one by one in this in-depth review of the Fuji X20.

▲Fuji X20

Fuji X20 is a new portable digital camera launched by Fuji this year. This camera is equipped with a new 2/3 camera that eliminates the low-pass filter. inch X-Trans CMOS II sensor with 12 million effective pixels. Not only that, the Fuji X20 also uses a high-performance EXR Processor II image processor. Thanks to the newly developed sensor and processor, the Fuji X20 has achieved a series of amazing levels such as a focusing speed of 0.06 seconds, a boot time of 0.5 seconds, a shutter lag of 0.01 seconds, and a shooting interval of 0.5 seconds.

The appearance is still retro

▲The body of the Fuji X20 is made of lightweight die-cast magnesium alloy

The body of the Fuji X20 is made of lightweight die-cast magnesium alloy. The wheel and zoom ring are ergonomically designed, high-precision milled from hard aluminum alloy, and are all made in Japan.

▲Behind the Fuji X20 is a 2.8-inch 460,000-pixel LCD screen

The dimensions of the Fuji X20 are 117?69.6?56.8mm and weighs about 333g (body only). Behind the fuselage is a 2.8-inch 460,000-pixel LCD screen.

▲The Fuji X20 uses a Fujinon lens with an equivalent focal length of 28-112mm

The body lens uses the same Fujifilm lens with an equivalent focal length of 28-112mm as the Fuji X10 Dragon lens, this lens has 4x optical zoom capability and the maximum aperture range is F2.0-F2.8. It adopts a structure of 11 elements in 9 groups, including 3 aspherical lenses and 2 ultra-low dispersion lenses.

The changes lie in the details

Although at first glance the appearance of the Fujifilm X20 is basically unchanged compared to its predecessor, after playing with it carefully, you will find that this camera has The changes are all in the details.

▲The position of the LOGO has been moved to the front

First of all, the position of the LOGO has been changed. The original X10 LOGO was located under the FUJIFILM trademark on the top of the camera, but this time the FUJIFILM X20 The LOGO is placed on the top right side of the front of the fuselage. The big reason why Fujifilm did this is that the front appearances of the X20 and X10 are so consistent that it is impossible to distinguish the two products without changing the position of the LOGO.

▲The buttons on the back of the Fuji X20 are designed to be more user-friendly

Secondly, the buttons on the back of this camera body have also undergone slight changes compared to the Fuji X10. On the Fuji X20, the AF focus point selection key has swapped positions with the function keys for selecting continuous shooting and bracketing. Don’t underestimate this change. The significance of placing the AF focus point selection button in the cross-disk area is that users can complete the operation with only one hand when selecting the focus point. This change is not only user-friendly, but also very consistent. Human body usage habits.

▲The new Q key is very practical

Of course, you may have noticed that the original RAW key in the lower right corner of the back of the Fuji X10 has disappeared, replaced by a Q key (Quick Select menu).

This Q key is another very user-friendly design of Fuji. The concept of Q key was first proposed on Fuji XPRO-1, and feedback from all parties is that this quick selection menu button brings great benefits to users. It is convenient, so starting from Fujifilm X-PRO1, this Q key has appeared on almost every X series camera.

▲Fuji X20 has rich modes

There are still 11 mode options on the wheel on the top of the fuselage, but Fuji X20 adds new creative filters and multiple exposures in the Adv mode With two options, the playability has been upgraded again! In SP mode, there are 14 commonly used scene modes. From the picture above, you can notice that there is an option called SR+ (Advanced Automatic Scene Recognition) in the roulette wheel. Advanced automatic scene recognition can quickly identify the shooting subject and every shooting scene including still portraits, landscapes and even sports. , and has 64 shooting modes that can automatically optimize focus, exposure, sensitivity and other settings.

▲The optical viewfinder of Fuji X20 has been greatly improved

The last thing I want to highlight are the several changes in the optical viewfinder of Fuji X20. First, there is a new eye sensor next to the optical viewfinder of the Fuji X20. When your eyes are close to the optical viewfinder of the camera during use, the optical viewfinder will sense it and automatically switch to the optical viewfinder. Second, the Fuji X20 integrates an ultra-thin electronic transparent LCD screen in less than 1mm of space in the viewfinder, so that the focus area, shutter speed, and other shooting data can also be seen in the optical viewfinder, and can also be displayed according to the scene. And the shooting conditions automatically change the color of the displayed information.

▲The optical viewfinder of the Fujifilm In other words, this optical viewfinder can not only help users quickly and roughly compose pictures, but also display basic parameter information during the shooting process. Therefore, this change further clarifies the positioning of the Fuji X20 and helps users better understand the main purpose of the Fuji X20 camera.

Summary:

It is obvious that the appearance of the Fuji X20 has not changed much, but in many small places, the Fuji X20 still shows that it is an upgraded product. The level it should be. By changing the layout of some buttons, the control is closer to the user's usage habits, and the upgrade of the new optical viewfinder is also more user-friendly. In general, just from the changes in some details of the appearance of this camera, we can see that the Fuji X20 is definitely a product based on the user's perspective. In addition, this time the Fuji X20 has a new silver color, and the silver body version looks more like a smaller version of its big brother Fuji X100S.

The lens has high resolution and the aperture F4 is the best.

The lens equipped on the Fuji X20 maintains high-resolution optical performance throughout the entire focal length range from the 28mm wide-angle end to the 112mm telephoto end. Every design part of the lens, from spherical mirrors, ED lenses to high-refractive index lenses, is made of high-performance optical glass with HT-EBC coating, which can effectively suppress ghosting and lens flare.

In order to test the lens performance of the Fujifilm Comparing at the same position, it was finally found that the Fuji X20 has the best imaging effect in the center and edges at the aperture F4.

After reading the outdoor test, let’s take a look at the results measured in the evaluation room. The maximum aperture range of the Fuji X20 is F2.0-F2.8, and the minimum aperture is F11. In order to speak with the most objective data as possible, we used the ISO12233 standard resolution test card to test the resolution of this camera's lens, and later used Imatest software to analyze the test results.

▲The center resolution trend of Fuji X20 at the 28mm end, click to view the larger image

From the actual test results, the Fuji X20 shows an obvious smoothing at the 28mm wide-angle end. to a straight downward trend. This is more in line with the design style of modern digital lenses, that is, the lens still has good resolution at its maximum aperture. It can also be seen from this trend that the Fuji X20 lens has the best center resolution at the 28mm end when the aperture is F4.

▲The edge resolution trend of Fuji X20 at 28mm, click to view the larger image

It can be clearly seen from the above picture that the edge vertical resolution of Fuji X20 is at F4 It reached the peak of 2712, and the edge horizontal resolution also reached a level of more than 200. So overall, when using the wide-angle end of the Fuji X20, the aperture F4 can achieve the best image quality.

▲The center resolution trend of Fuji X20 at the 112mm end, click to view the larger image

The maximum aperture of the Fuji X20 at the telephoto end is F2.8. The trend of lens resolution is similar to that at the wide-angle end, rising slowly and then falling sharply after the aperture F5.6.

▲The edge resolution trend of Fuji X20 at the 112mm end, click to view the larger image

Although the change trend of the edge resolution at the telephoto end of Fuji X20 is not obvious, it can still be seen When the aperture is set to F4, the edge horizontal and edge vertical values ??are the highest. Combined with the previous horizontal resolution, the best aperture of the Fuji telephoto end is also F4.

▲A partial screenshot of the real shot at indoor aperture F4

Summary:

The conclusion we got from the objective test is that when everyone uses Fuji X20 , no matter which focal length is used, the best image quality can be achieved by adjusting the camera to the aperture F4, so feel free to use F4! I will accompany you to watch the meteor shower fall on the earth~~~~

As a DC camera, ISO800 is fully usable

This photo was taken under the condition of ISO400. We intercepted a part of the picture and enlarged it 100%, and we can clearly see that the details of the texture on the door are preserved. It's still good. So everyone can use ISO400 with confidence when using Fuji X20.

But after reaching ISO800, we can clearly see that the image begins to have a small amount of noise visible to the naked eye, and the details of the image begin to be lost. So ISO800 is considered the ultimate sensitivity of Fuji X20.

Fuji’s official promotion of the Fuji Noise can also be controlled to a low level at low sensitivity. ? Below we compare the actual shooting effects of ISO100 and ISO12800 sensitivity of Fuji X20 in the evaluation room to test the ultimate sensitivity of this camera.

▲Sensitivity actual measurement comparison chart

We can clearly see from the above picture that at ISO100-ISO400, the Fuji X20 can get a clearer picture. In the picture Every part of the detail is retained very completely, and when it rises to ISO800, you can clearly feel that there is a small amount of noise in the picture, but it is still within the acceptable range. Starting from ISO1600, the amount of noise visible to the human eye increases significantly, and a large amount of detail begins to be lost. When reaching ISO3200 and above, the number of noise points is very large.

So by comparing two sets of indoor and outdoor real-shot screenshots, we came to the same conclusion. The ultimate sensitivity of the Fuji X20 is ISO800, but if you want to get a more perfect picture quality, you should try to keep it at ISO400. and below.

Summary:

In general, whether the effect of high sensitivity is good or bad depends entirely on the performance of the camera CMOS and image processor. For a camera like the Fuji X20 For a consumer-level DC machine using 2/3-inch CMOS, the extreme level of ISO800 is already satisfactory.

General distortion control

The focal length of the widest end of the Fujifilm X20 lens is equivalent to 28mm, which belongs to the wide-angle range. Therefore, the issue of distortion is also something that the Fujifilm X20 camera must face. For a lens, whether the distortion is obvious directly determines the quality of the image at the edge of the wide-angle end. Some of the XF Fujinon wide-angle lenses previously launched by Fujifilm have relatively good distortion control. So let’s take a look at the Fujifilm X20 How well the camera's distortion is controlled.

The picture above is a sample taken outdoors. The focal length of the lens is 28mm.

Since distortion for a wide-angle lens is the image quality at the edge of the image, in order to see the actual distortion of the Fuji X20 lens, we intercepted the leftmost part of the photo and enlarged it 100%. Judging from the enlarged partial screenshot, there is almost no deformation at the edges, so the lens of the Fuji X20 camera is quite good at controlling distortion.

▲Fuji X20 wide-angle end distortion test results

We still use Imatest software to test the Fuji X20. The test results are expressed in percentages. The closer the value is to zero, the smaller the distortion. If the test result is negative, it indicates barrel distortion and the screen expands outward. On the contrary, it is expressed as pincushion distortion, and the picture shrinks inward. The value obtained through the distortion test of the wide-angle end of the Fuji X20 is -0.99%, which is barrel distortion, but the test result is less than 1%, so the distortion effect is not very obvious, but this result can only say that the Fuji X20 is at the wide-angle end. Distortion control ability is average.

▲Telephoto end distortion test results of Fuji X20

The test result at the telephoto end is 0.0465%, which is pincushion distortion. However, the test result is very close to 0, so the pincushion distortion is not obvious.

The macro is very powerful

The most powerful thing about the Fuji X20 lens is its close-up effect. The super macro mode can be turned on through the macro switch on the wheel on the back of the fuselage. The close-up distance can reach 1CM.

▲Real shot sample in super macro mode, click to view larger image

Summary:

It just snowed in Beijing two days ago. This picture The snow in the picture is actually just a small piece on the branch, but by turning on the super macro mode, you can take a close-up shot of the snow. After zooming in, you can clearly see the details on the surface of the snow. Therefore, the super macro mode of Fuji X20 is very powerful. Through this mode, we can carry out a lot of very interesting artistic creations.

F8 vignetting is basically eliminated

Light loss is also an inevitable problem for every lens. When the lens uses a large aperture, the phenomenon of darkening in the four corners of the picture is called loss of light. , also commonly known as vignetting. And for wide-angle lenses and large aperture lenses, the vignetting phenomenon is particularly obvious. The maximum aperture of the Fuji X20 at the wide-angle end is F2, which is within the range of large apertures, so the Fuji X20 cannot avoid the phenomenon of loss of light.

▲The Fuji X20 has basically eliminated the phenomenon of all-round light loss at F8.

Summary:

Through comparison tests, the Fuji X20 has four-sided loss at F2. The light phenomenon is relatively serious, but at F8, the vignetting around the screen is basically eliminated.

The out-of-focus edge effect is average

Another benefit of a large aperture lens is that when taking photos with lights in the background, you can get a nice round spot out of focus. Whether the shape of this circular spot is good-looking or smooth is directly related to the number of aperture blades of the lens.

▲Indoor test

Based on the principle, the aperture of the lens cannot reach an absolute circle, but the more aperture blades, the closer it will be to a circle. The most typical example is the Russian Tair 11A 135mm f/2.8 lens. The number of aperture blades of this lens has reached 21, the highest among all lenses currently, which means that the aperture is round at any gear. The lens of the Fuji X20 uses a 7-blade aperture design. Judging from the results of indoor test shooting, the aperture shape of the Fuji X20 is relatively rounded at the center, but will show some very irregular deformations at the edges.

▲Outdoor test

Summary:

During the actual outdoor shooting, we also came to the same conclusion, that is, the aperture at the center is relatively round. It looks good, but the edges are average.

Focus peaking adds to the fun

▲The Fuji X20 still uses three focus methods

The Fuji X20 still uses three focus methods, namely MF manual, AF-S single focus and AF-C continuous focus. However, the Fuji X20's manual focus mode adds a peak focus function. The peak focus function was first proposed on Sony's NEX series. Its principle is to highlight the area with the highest contrast in the picture. The two X series products launched by Fuji this year (Fuji X100S and Fuji X20) are equipped with peak focus function, which is also a brand-new highlight.

▲The left side is out of focus, and the right side is in focus

In the actual operation process, we must first select an object to be photographed, and then focus the camera Set the mode lever to the MF (manual focus) position. At this time, because the focus was not successful, there was no peak on the screen. As we turn the cross disc on the back of the Fuji X20 body, we can see that the camera will automatically identify the position of the focus point and display it on the screen in a 100% magnified manner. After the process of focusing on the subject begins, the closer to achieving focus, the more obvious the white particles appear on the screen. These white particles are the so-called peaks. Finally, we can judge whether the camera is in focus by observing how densely the peaks appear on the screen.

Summary:

Peaking focus is a more interesting focusing method. Its advantage is that it can ensure that the subject is in focus accurately and quickly. For a camera like the Fujifilm X20 that focuses on autofocus, focus peaking is more novel than practical.

Focusing speed as fast as the blink of an eye

To say that the camera with the fastest autofocus speed among DC cameras is the Fuji X20. With the newly developed X- Using the phase contrast focusing technology on the Trans CMOS II sensor and the high processing speed of the EXR Processor II processor, the Fujifilm X20 achieves amazing performance of a focusing speed of 0.06 seconds, a boot time of 0.5 seconds, a shutter lag of 0.01 seconds, and a shooting interval of 0.5 seconds.

In particular, the focusing speed has been increased to only 0.06 seconds, which is basically close to the speed of a human blink. This focusing speed is perfect for daily snapshots.

▲Real shot sample, click to view larger image

Summary:

I took the above photo in the Summer Palace in Beijing, the park There are many people like this aunt who sell small toys. I was about to go up the steps when I suddenly noticed this aunt with a mask on her face walking over. In order to avoid embarrassment, the moment she came down the steps and I came up the steps, I quietly pointed the camera hanging on my chest in her direction and pressed the shutter. The whole shooting process ended very quickly, because I hardly stopped. At first I thought the photo must be out of focus, but when I looked back at the photo, I unexpectedly found that the photo was in perfect focus and exactly right. Starting from this photo, I trust the focusing speed of Fuji X20 even more.

The continuous shooting effect is good

The combination of the improved processing speed of the EXR Processor II processor and the fast reading speed of the X-Trans CMOS II sensor enables the Fuji X20 to shoot at 12 million At full pixel resolution, it can achieve a continuous shooting speed of 12 frames/second (up to 11 frames). This is very useful for photographing moving objects and selecting the best-performing photo after the shot is completed.

We adjusted to ultra-high-speed continuous shooting mode (up to 11 frames/second), and selected a fixed position to test the continuous shooting of cars on the road.

Summary:

The final results displayed in animated images show that the high-speed continuous shooting function of Fuji X20 is indeed pretty good. Basically, every photo remains the same after 100% magnification A clearer and more detailed picture.

Rich filter effects to choose from

The Fuji X20 has a rich set of built-in filter effects. The rich filters reduce the trouble of post-processing for users and also It meets the needs of many users who like different picture styles.

▲The Fuji X20 has a variety of creative filter effects to choose from

Summary:

Select the Adv mode on the wheel on the top of the Fuji X20 body. Creative filter mode can be selected. There are thirteen filter types including toy camera, miniature landscape, popular color, dynamic tone, local tone (red), etc. Users have a lot of choice.

The charm of film simulation mode is irresistible

As Asia's largest film manufacturer, Fujifilm will naturally not forget its most proud products. Therefore, on the Fuji X20, we have seen many special modes that simulate the imaging effects of well-known films produced by Fuji. Among these film simulation modes, there are also some familiar film models, such as Provia, Velvia, and ASTIA, etc.

▲The charm of Fuji X20’s simulated film effect is irresistible

Summary:

Fuji X20 can definitely capture a lot of people just by virtue of its unique simulated film effect. The heart of a literary and artistic youth, and judging from the actual shooting effects, the analog film effect does have a unique charm. It can be said that it completely inherits the essence of those classic film models in the film era. This is the most charming and attractive point of Fuji cameras.

Final summary of the evaluation:

It’s finally time for the final summary. After reading the above series of reviews, you may be able to feel the joy brought by the Fuji X20 to some extent. The advantages of this camera are very clear: bright appearance, practical optical viewfinder, fast focusing, and many filters. Therefore, the Fuji X20 camera is very suitable for use by these three types of people.

The first category is appearance control, and the retro appearance of the Fuji X20 can definitely satisfy the preferences of these people. The second type of people are street sweepers. The Fuji X20’s ultra-fast 0.06 focus speed and advanced bright optical viewfinder are definitely the best helpers for street sweepers to capture photos. The last category of people is the artistic youth. The simulated film mode of the Fuji X20 will definitely fascinate the artistic youth. The charm of the colors cannot be described in words.

Of course, no machine in the world is without shortcomings, and the Fuji X20 is no exception. After using it as a whole, you will find that the battery life of the Fuji X20 really needs to be improved. It is also worth suggesting that Fujifilm should improve by adding a time lag compensation frame to the optical viewfinder of cameras such as the Fuji X20. Otherwise, the optical viewfinder will not play a big role when you want to accurately compose pictures.

The last thing I want to say is that the Fuji X100S and X20 have been officially sold exclusively on the Fuji Tmall official flagship store this week, so if you have friends who like the Fuji X20 camera, you can go directly to Fuji Go to the official online store to purchase.
