Ask professionals to answer questions about photography. I'm Xiao Bai. Now use Pentax k52s, because many people say Pentax is suitable for playing with old lenses.

First, Pentax and Taikuma are the same company. Cool Horse is the lens brand before Pentax. Because the previous lenses were all threaded and all kinds of cameras were universal, Pentax made a brand lens alone. In the end, because everyone started to use their own dedicated interfaces, Taikuma could only use Pentax, so it was easy. Finally, this brand was cancelled. As for Schneider and Zeiss, they are both lens manufacturers. Like Longteng and Sigma, they mainly make lenses, which are compatible with various institutions. For example, Zeiss's lenses include Nikon, Canon, Sony and Pentax, while Nikon's lens only has its own interface.

Second, the reason why the so-called old people use Pentax is because Pentax's camera has made a very good reservation for the old-fashioned manual lens operation, especially for metering and focusing tips. Pure manual lens, the machine can accurately measure light, and the small green dot is more convenient to use than Nikon Canon. In addition, Pentecox's old lenses, such as A series, M series, K series, and even Taikuma series with M42-PK adapter ring, are all peak works and cheap. In addition, with the preference of lens adjustment in the film era, it is possible to take very attractive alternative photos on digital cameras, such as very oily, sharp or LOMO.

In fact, you can play with the elderly, using adapter rings, Nikon and Canon, but it's not as convenient as Pentax. Of course, there are two full-frame machines in CN, and rich people burn high-end machines to play with the elderly. Personally, I feel that the real poor are entertaining themselves (except for a few precious old people)

Third, we should distinguish between the old man and the manual lens in production. The so-called old people are probably the products of the 1970s and 1980s or the 1950s and 1960s. Are they second-hand or second-hand? German brands such as Zeiss and Leica still insist on producing high-end manual ptz. As for the shanzhai, this is really rare, the lens is very accurate, and many people do it, but there are also some German heads, and the white characters pretend to be the scarlet letter, and the later ones pretend to be the early ones. So it's best to visit and understand more. Playing with old people is no different from playing with antiques. You should understand this product, because both of them are old men and their colors are different. There must be a difference between the colors used by fools and those used by collectors. Therefore, it is normal that the prices of different products of the same lens vary greatly.
