| p.1 #3 · Seek info: 5D III manual focus confirmation |
I have a ZE 50 MP & did some careful testing. I had to focus adjust it - takes something like +15 on my 5D3. I made a small pencil mark on the barrel to figure out how to focus adjust it (focused using liveview, then marked the correct focus, and worked with focus adjust until it beeped when the pencil mark was lined up correctly).
I MA'd it by turning the focus ring from infinity back toward correct focus. I found that if I focused by going from near MFD toward infinity, it gave me focus confirmation too soon (it front focused). So at least on my copy of the lens and 5D3, I always need to go from the infinity side toward the focus point or else it will be noticably off if I am shooting wide open. It might not look off for a landscape shot where you were focusing further out and stopping down.
So yeah, it's workable but still a bit fiddly. IMO, YMMV, IIRC, and the usual disclaimers and stuffs.
