FM2 Focus problem
i have a problem with my Nikon FM2. While shooting focusing seems nice, but on print most of the photos are unfocused. Any ideas?
Thanks a lot..
Possibly a misaligned focus screen?
Is there a way to find out if that's the case, or should i go to the pits?
Have you verified that this is not in the printing process? You might want to examine the negs closely with a loupe to see that the negs are out of focus, not just the prints. Also, is it the same focus all over or are there areas of the image that are more in focus. There could be a film flatness issue, you could tell that if the focus is better in some areas of the image than others. If is the same all over, I would agree that the most likely culprit is a misaligned focusing screen.
Actually i'm pretty sure there is no problem in the printing process. It has happened to an ilfordfx hp5 and to two colored fuji smth films. I've developed the first and the other two went to seperate laboratories.
It was really strange i could aim normally..
So should i take it to a mechanic or is something i can work out?
PS in the blurred photos, it's in the whole picture

When you enlarge the HP5, is the grain in good focus? This will tell you if the enlarger is in focus, regardless of the image. It would be odd to have nothing in the image in focus.
Take the lens off and look above the mirror. Check to see if the metal frame that holds the focusing screen is locked into place. Dealt with this on a certain F100-based off-topic Nikon body. Couldn't figure out why the electronic rangefinder disagreed with my eye. Turns out, the frame had become unlatched and the screen was slightly tilted.

Is this a new problem, or is this a "new to you" camera? If it is a new to you camera did you shoot a test roll using all the apertures and at least one infinity shot at the smallest aperture? If you made that test shot and it is out of focus here is a list of what could be wrong.
You were shaking, all the labs messed up, there is something hiding between your mirror and your shutter, there is something wrong with the film guides (pressure plate or lands), your lens and screen are both mounted wrong, you were "floating" a lens and are not that steady, or your camera is done.
Before you load more film check the film pressure plate, and machined flats, the pressure plate on the door should be springy, and the machined surfaces clean. Remove the lens or front cover, and with the rear door open set the camera in B and open the shutter and look through to be sure there is nothing in there. Check the screen, I don't think you can remove the screen on an FM2 but check it anyway if you can remove it Nikon has instructions, follow those to remove and replace it. Be sure your lens is properly mounted to the camera, not loose or shaky (no lens "floating" either, this is a test roll). Load film, and shoot focused on something at infinity at all apertures, then something close (less than 10 feet) at all apertures, make all of these shots with the camera on a hard flat surface or tripod and use the timer so you are not touching the camera when it takes the photos. If after all that you are still get back out of focus photos, it is either your lab, or a problem with your camera that you can not easily fix at home.
