Hello, I am very new to the M42 world and had never thought about jumping into it but one day I came across a picture of Zenit Z122 via Google and fell in love with its look. Z122 is one handsome camera, so I have tried to find info on it. So far I have found not much, and this surprises me as the camera has been released for over 20 years and over 1,000,000 unit has already produced (not sure if this statement is correct, I got it somewhere on the internet). Doing research on Z122 gets me some info about the M42 world. What interests me is that, though having the same lens mount, not all M42 lenses function on a particular M42 body. And here are my questions: Is Zenit 122 (M42) a reliable camera? Please share with me your impressions. Do Mamiya and Tarkuma (M42) work on Z122? Or I have to stick with Russian lenses specifically designed for Zenit cameras? So far I believe Bessaflex TM is the best M42 camera, where can I find one? Thanks & Best, Chanchai A. PS: Please feel free to educate me on M42 matters, especially the body-and-lens combination matters. Thanks.
