Besides focal length I do not see any difference in IQ, etc between these two lenses. Obviously I am comparing the MC to MC or SC to SC. But what's up? The price sure is different.
The 50 would be fine.Likely only the 50 frame since that always shows anyway. The have a lens show the 135 frame it would have to be a 35mm mount and the 90 is a specific mount too.
