Comment on what kind of lens is the Leica m rokkor?

First of all, M refers to Leica, ROKKOR is the name of Minolta's lens system, and M-ROKKOR is a photography system jointly launched by Leica and Minolta - the Leica CL system.

So strictly speaking, M-ROKKOR is not in the Leica lens system. It is the lens for the Leica CL camera jointly launched by Leica and Minolta. The Leica CL body is designed and produced by Minolta to match the CL body. The first-generation M-ROKKOR lens was designed and manufactured by Leica. The lens port had Leitz English and the lens body was engraved with the words "Made by Leica". However, later Leica withdrew from the cooperation with Minolta, so the second-generation M-ROKKOR Minolta continues the lens structure designed by Leica and produces it itself. There is no Leitz English on the lens port. As for the third generation M-ROKKOR, it is completely designed and manufactured by Minolta and has nothing to do with Leica.

Because it is the product of cooperation, Leica did not use its real skills to design and manufacture this lens. It can be seen from the name of the lens. Why should it help to improve the Minolta ROKKOR lens for no reason? Moreover, it can be seen from the selling price that Leica did not use heavy materials in production and design. The out-of-focus linearity of the first-generation M-ROKKOR lens manufactured by Leica is very obvious, which is inconsistent with the high-quality optics of Leica lenses. This is also in line with Leica’s The market strategy is just a cooperative product and a cheap version of the M system. It cannot take away the market of its own genuine lenses. Naturally, it has to sacrifice performance.
