Camera repair confirmed that the AF is off on my 5dc, significant backfocus. Cost to recalibrate and clean does not make sense ($200+) and I had been using the body as a manual focus camera anyways. Pretty much has had a C/Y Zeiss 50mm f/1.4 on it for the last year or so, but the combo was only occasionally used, EOS-m was more convenient for manually focusing (smaller set up and live view).
Otherwise the body works fine. Have a S type precision matte focusing screen and running Magic Lantern pretty much maxes out the manual focusing aids. Have a variety of manual focus prime lenses from 20mm to 135mm and appropriate adapters, both EOS and EOS-m.
I am thinking that, despite the cons typically associated with manual focus zoom lenses, the convenience of a mid range zoom and having some sort of closer focusing “macro” mode would offset the cons I had with my 50mm prime. The legacy world seems to really like the C/Y Zeiss 35-70 f/3.4 and I like how my 50mm renders images, so that seems like the most obvious option IF I am trying to maximize IQ on a 12MP camera.
Looking for opinions on other lenses (yes, I know this is the camera subforum), as well as other ideas on what to do with this camera, I have already considered selling at discount, but decided to keep it for now, maybe give away at on the holiday thread...
