I tried all setting options on the camera and couldnt enable focus wide open and shoot stop down. Whenever I changed aperture on lens, iris stop down/up right away.
This is annoy for a few reasons, 1, you can't do hyer-focus to max depth of field in manual mode. Usually, I select Manu mode, back button focus and recompose for anything non human to maximize DOF or subject I want to be in the best focus (I don't want camera to decide in focus zone or transition) 2. For stop down AF tracking, less light enter to AF system, the focus will be slow and inaccurate. Early Z7/Z6 have this annoying limitation (focus aperture the same as shooting aperture before f5.6) but I believe they fixed in later mode with feature you can select.
I have used and bought RX1R3 almost 1 year and usually find this kind of stuff within week but due to limited time, I no longer shooting much and didnt digger deeper on this until I plan to take it as my only camera for upcoming business trip.
Any help, confirmation will welcome. I hope I missed something here though I have done some extensive research on this. Looks like either Sony didnt sell much this camera or most people doesn't care this feature.
Hi Michael - I won't be of direct help. I just wonder if this lens might have some focus shift that stopped down AF avoids having to deal with? Has anyone tested for focus shift? It's been over 10 years since I've used the original RX1 and didn't test for it back then...
Haha, I can’t even test focus shift with this one. However, if I remember correctly, RX1 allow me focus wide open by disable set “effect on”. I don’t remember I noticed focus shift before.
