Originally posted by EJMzagsfan Thank you. I don't know. I took one roll and I shot at 2.8 for most of it and most of it wasnt in focus. One shot was, and one eye was in a shot. I'm not sure if it was user error or not. Is 2.8 a lot thinner on medium format? Would a CLA clear that up if it is the camera?
Depth of Field is generally very shallow at f/2.8 with medium format. I might guess that many of your photos were back-focused? The S2/S2A cameras have a design flaw in that the ground glass and focus screen drift upwards (away from the mirror) over time. You can do search for Bronica S2A focus screen and you'll find lots of info on it.
It's not very difficult to repair from what I've read. My S2 still back-focuses a bit, as I don't have the ability to repair it myself, and I've not found someone to do it for me.
