1.？ Pentax Cool Horse 55F 1.8 Price: 400+
This lens has very good focusing feel, sharp image, retro color and charming bubble Jiao Wai. Relatively speaking, full-open picture quality is also acceptable. After receiving f2.8, the picture quality and clarity are greatly improved. After F4, we can catch up with the imaging quality of modern lenses.
2.？ Seagull 58F2 Price: 100+
One of the excellent lenses made in China, as the standard lens of Seagull DF 1 camera, has a very large market share, and it can be won at around RMB 100. His Jiao Wai is very distinctive, and it is a very popular rotating Jiao Wai at present. And because it is modeled after the famous Zeiss small B lens, its full-open image quality is also very good.
3.？ Eight Feathers 58f2 Price: 300+
Like the seagulls above, they are all small B lenses like Zeiss, but because of the different aperture selection, the rotating focus of Hachi is stronger than that of seagulls, but the corresponding full-open image quality will be slightly worse. Because of the different glass used, its color is very different from that of seagulls.
4.？ Kangtaishi G90 Price: 800+
Kangtaishi G90 is the cheapest Zeiss lens with T mark that we can buy. What is commendable is that it also supports autofocus on some micro-singles, and the picture quality is excellent and very sharp. The color is also full of Zeiss style. The disadvantage is that in the case of full opening, there will be a serious purple edge. But compared with the price, this shortcoming is nothing at all. Although its price has reached the "sky-high price" around 800 yuan, I still think it is an extremely cheap lens.
5.？ Phoenix 50 1.7 price: 100
This lens has a large number of rich bayonet options, whether it is Canon, Nikon or Pentax pk port, corresponding models have been introduced, even micro-orders can be used by switching. In actual use, the full-aperture image quality of 1.7 is not satisfactory, but if it receives about 2.8, it can have good image quality. The stock of this lens is very large, and the cheapest price is 50+, but for the sake of safety, I suggest that the starting price should be around 100 yuan.
