  1. I used to have a P30 t. It was a great little camera, but I noticed my 50mm lens moved a little past infinity. I called it my Buzz Lightyear lens - "to infinity; and beyond!" Anyway while doing some close-up macro work, I noticed my lens wasn't focusing where it should. After a few experiments with a tape measure, I found that the focus for the film was different for the focusing screen. Objects in the final prints were in focus slightly closer to the lens than what I focused on. That may be the cause of your problem as well.
  2. There appear to be 2 aspects of the FM3a for which there is no universal agreement. One is the maximum length of aperture priority time exposures, the other is how manual shutter speed settings are powered with good batteries installed. Are they mechanically controlled or electronically controlled?

     

    One thing I do know is that time exposures will go quite a bit past the advertised 8 seconds.

  3. Has anyone figured out a good one-hand technique for the exposure

    compensation dial on the FM3a? I know the -1 stop button is quick

    and easy, but the dial from -2 to +2 stops is a pain. There seems

    to be no way to work it without using 2 hands. 3 would be even

    better.

  4. I think I know what J. is asking. Let's say you are using a 50mm lens with a subject 10 feet away. It's bright and sunny out, so you are at f/16. Classic depth of field calculations say that objects will be in focus from 6.3 feet to as far away as 23.6 feet. Distracting objects may be in the frame.

     

    Now let's say you intentionally mis-focus at 7 1/2 feet rather than 10 feet where your subject is. Now, objects will be in focus only from 5.2 feet to about 13 feet, just 3 feet beyond the subject. Distracting elements have been blurred.
