Nikon F100 - [ ] vs [+] mode?
So I've been struggling with my Nikon F100 for quite a while. Every roll of film put through (and with various manual and autofocus lenses) have images that turn out just slightly out of focus. However, there are times when it is in focus and I'm wondering: Does selecting [ ] vs [+] on the back make a difference? In this last roll I tried both options and some images worked and others didn't... and I'm wondering if this is the deciding factor.
Note that I use only one single point of focus (the center).
I'm shooting various MF/AF lenses and respond to the green dot. I've checked the focus green dot and it's pretty spot on (green dot as well as viewfinder). But the images, for whatever reason, just don't correspond as being in focus also.
If anyone can share their experience, that'd be great!!
