Oooh, loads lol. 50mm is very common in m42 & I do love variety. List in ascending order of sharpness
Steinheil munchen cassaron f2.9 needs cleaning.
Steinheil munchen cassar f2.9
Carl Zeiss tessar f2.8
E Ludwig Meritar f2.9
Pentax-m f2
Carl Zeiss pancolar f2.8
Auto Mamiya sekor f2
I havent pixel peeped round the corners with these because for my level, soft corners are ok, its based on centre area. The sharpest wall to wall is probably the pancolar. The e Ludwig and steinheil munchen are silver, look great on the camera and are cheap and fun to use. Mine is the slightly conical e Ludwig and it is great. It isn't quick to use but that just means you factor in thinking time. I also have a super tak 55 and two Helios, 44-2 & 44-4 so I have sharpness and variety in abundance. My mamiya is unaltered so I always open her up to focus and I have a magnifying eyepiece. Today I am expecting a yashika auto Yashinon f1.7 and I am very excited. The Yashinon is my most expensive at £38 but the average is probably £20. The mamiya was £12
and when you think that in many cases the glass and build quality can rival a £500 prime, they are a bargain
