I have two legacy 50s: Takumar 50/1.4 and Rokkor-X 45/2 The Takumar is by far my favorite. Easy to find the ap and focus ring while looking through the vf. Great sharpness starting around 2.0 and on. I like the color. But it flares like it's going out of style -- especially with the Sony patented purple flare. The Rokkor-X flares less, but isn't as sharp, and the ap and focus rings are small and close together. I could just keep them both, but was wondering if anyone had another cheap 50 to recommend. One that maybe is a combo of the two above? Sharp, less (or very little or no) flare, easy to find the ap and focus rings? Good color and contrast? The ones I can think of are: Oly OM 50/1.4 -- my experience with OMs are not so contrasty Canon FD 50/1.4 -- I'm thinking this might be a contender, though I find their focus rings not smooth Nikon MF 50/1.4 -- I don't know anything about Nikon lenses Pentax K-mount 50/1.4?? -- maybe like a Tak, but with less flare?? Mionolta/Rokkor MD 50/1.4 -- I've never tried one Anyone use these on an a7? Any report on sharpness, handling, color, contrast? edit: found an FM thread http://www.fredmiranda.com/forum/topic/1299924/0 Also found this site which has some 50s, and other FLs as well as some of the native glass: http://erphotoreview.com/wordpress/?cat=133 Still open to people's opinions/experiences, though.
