hey /p/ technical question:
do i just focus unproperly or does wearing glasses infect the focusability
because most of the pictures i take at an aperture of 1.7 come out pretty unfocused/the focus is shifted a few centimeters before or after the subject

picture related, cause it is out of focus and it propably isn't motion blur, because it was shot at 1/1000 s

I dont know how you can focus incorrectly :/
As long as the subject is sharp in your viewfinder - the photo should come out perfect.

If not, then there must be something wrong with the glass/sensor.

Although I dont wear glasses, I'm positive that glasses wouldn't effect focusing, unless your wearing an incorrect strength maybe?

Test your focusing out with a different camera, to try and troubleshoot the problem.

Are you using an autofocus SLR? 'Cause those really aren't generally designed to let you manually focus with anything faster than f/2.5. So stop down or use autofocus.

(If you're using a manual-focus SLR with the nice focus aids and such, then I got nothin')

no, no autofocus slr. old manual focus with microprism...

and at first anon: no. doesn't come out in this shot. but in other shots you see sharp focus

gonna test it with a different camera but i think it's just lazy focusing

You probably just need a little more practice. Glasses should not affect the focus.

Perhaps you have an incorrect diopter set (newer cameras) or attached (older cameras)? Then you're correcting for vision problems that aren't there when your glasses on, and it fucks things up. I was on a hiking trip with my grandfather last summer using his FM2 when I notice a crack in the front finder glass - after screaming and waving my arms about for a bit, I unscrew the eyepiece to find a shattered correction lens.

"Oh, I forgot to tell you that was in there", he said. Turned out that ruined a whole roll of unique shots - everything was focused like a foot too far back, I think.

your mirror can be misaligned. your mirror rests on a notch in the mirror chamber. If the rubber on the backside of your mirror wears off, the mirror will hang a few degrees lower: both Nikon FM's I had in my hands had this problem

OP photo is clearly defocused. take a photo of an A4 sheet of paper with small text at your widest aperture and closest focusing distance. mark where you focused, and take 2-3 photos and refocus evey time.

attached photo related. I used tape to patch up the rubber wear on my mirror, and recollimated my first Fm myself. My second FM got the rubber professionaly replaced.

1) Strong prescription lenses do definitely have some affect on focusing ability. Not because they impede your view, but because people with strong prescriptions generally have eyes that are slower to focus. I wear what are classified as "very strong" glasses and I definitely have difficulty making minute manual focusing adjustments in some situations.

Your lens may just be backfocusing.
