    Hi All,

    Consistently, tack-sharp focus is a short distance behind most of my subjects - indicating an annoying back-focus suspicion with my Minolta XG-M.

    Observation:

    A while back I removed the Viewing Screen to clean - put it back correctly (gloss side down) - it sits (10th of a mm) above its little rail. I recently removed it again to check alignment - it sat back in the same position.

    I’m sure I’ve used two different lenses with same results.

    Any guidance? If I put the screen in backwards I may be able to hack this problem away (get my logic)

    I’m aware I may have to do a precise measurement with the film plane indicator and a ruler.

    Any thoughts? My eyes aren’t that bad lol.

    Why is above its rail instead of resting on it?
