1. Simple check. Load slide film. Set lenses to infinity. Take photos of distant objects. Get film processed. Look at distant objects with 10x loupe. If they are not sharp in the center, and each corner, something is wrong.
If the problem is with only one of the lenses it is the lens. If the problem is with all the lenses the problem is with the body.
2. You can also use another SLR with a long lens as a collimator (it needs to have some sort of focus aid on the viewfinder screen to focus on though). Set the collimator camera up on the tripod with a strong light behind the viewfinder window with the long lens (200mm works well) set to infinity. Point camera with lens to be tested into the lens on the collimator camera. If the screen in the collimator camera is in focus with both lens set to infinity, the lens and viewfinder system is accurate. Now open the back of the test camera and place a piece of groundglass* against the film rails over the opening. Check image on ground glass. If the focus aid in the collimator camera is sharp then the lens in in focus.
*If you don't have small piece of groundglass, a piece of Scotch Tape works surprisingly well, just make sure it is pulled taunt between the rails, and clean any adhesive residue from the rails afterwords

> Dave,
There is nothing wrong with those three M lenses. They can deliver sharp results. How is the camera's focus accuracy? Regards, Bob S.
