Hello everyone, some months ago I bought the 50mm C lens for my RB67. It is a pretty nice lens, but I'm not thrilled with it. It has quite a lot of barrel distortion, and when I shoot colour film I notice a lot of chromatic aberration. It is also noticeably not as sharp as my 90mm KL. So I am thinking of picking up a 65mm KL lens - does anyone know if the CA and/or distortion are signifcantly better with the 65mm KL than with the 50mm C? Thanks!
