After having run about 15-20 rolls through my Autocord, I've started to notice that on shots taken at a larger aperture, where dof is narrower, I seem to miss the focus. I processed 5 rolls from a recent family trip, and it was frustrating to notice that a few were out of focus when I know for sure that the WLF was showing it in focus. My question is, what is the easiest way to remedy this? When I take the WLF off, I don't see any way to adjust the mirror or gg. Do I have to adjust the taking lens?
