Hey all, Question - I have been using the Techart Golden Eagle (the one mentioned here) https://chadwadsworth.com/2015/08/30/913/ to adapt my wonderful Contax G lenses to my A7RII. It's been a year that has had a few quirks, but mostly problem free. I most often use the 90, but sometimes the 28. Besides the smearing that has been talked about sometimes, and that I haven't found to be too big a deal, I was recently on a shoot in bright sun and was shooting at speeds of 1/4000 to 1/8000 and noticed the bottom of the frame wasn't getting exposure - almost like pushing a flash sync too far but I wasn't using flash. Does anyone have any idea why this might be? here's 1/8000 here's 1/5000 here's 1/4000 (fading more - problem is minor) here's 1/3200 (seems to no longer be an issue) I've been able to replicate this issue - has anyone else had this or similar issue with the Contax/Techart set up or any other lenses? Is this a wide angle thing? I can live with it if I can only shoot up to 1/3200 with this lens as I don't use it a ton, but I haven't had it with the 90 as far as I know, I've shot with that lens a lot in all conditions. Just curious what's going on.
