Hi all sifu,
After a month of shooting, I'm back with another question. This time, I'm having some issues with focusing.
I have been shooting on a Nikon FE and I just got the first roll developed and scanned. For some reason, 90% of all my photos focused closer than 5m or so have been pretty out of focus. I'm certain that while shooting the focus looked fine in the split prism finder, but somehow that didn't quite translate to the film plane.
Therefore, I would like to know what the possible reasons for this might be. I've read online from various sources to check if the focusing screen is positioned right. I've removed the screen and set it back into the bracket. That made about 0.10m difference at 0.55m point of focus. Other sources have pointed to misaligned mirrors but I have not found the mirror to be loose. What are some of the more likely reasons for such a phenomenon?
Another question I'd like to ask is how can I check the focus at the film plane. I'd like to do this so I can compare the focus in the viewfinder and at the film plane. I have yet to find any concrete methods to do this so any suggestion is welcome!
Some photos have been attached for reference. This doesn't seem to affect objects at infinity but for closer focus distances the effect is apparent. Shooting stopped down helps but it's still not quite as sharp. On a related note, this was shot on expired Ultramax 400 that I undercompensated the loss in sensitivity for so most shots came out underexposed. Focus is usually set at the center of the frame.
Thanks in advance for your help and kind attention!
Edit: Forgot to mention, lens is a 50mm f1.4 AI
Edit 2: I'm also using a +1 diopter eyepiece for the F3 on the finder (even though I don't need the diopter adjustment) to keep the dust out of the finder.
