Which Diopter for an M3 ?

  1. How do you correctly determine which diopte to use with a M3 ? I am not totally without some foucusing ability but with parallax I have some trouble. Any one that cna help me figure out which one I need before I buy one.?
  2. You will have to see an optician to determine the correct diopter for
    your particular eye. They come in - and + corrections. Take into
    account that the viewfinder on the M6 has a -0.5 correction built in
    according to the technical specifications in the instruction manual.
    The M3 may be the same, I'm not sure, you would have to check with
    someone like Steven Gandy or any other Leica expert on this site if
    you don't have the M3 instruction book. If the viewfinder has indeed
    got a correction built in for example -0.5 and your eye test
    indicates a -1.5 correction is for you then you would have to get a -
    1.0 diopter correction lens, about US$80. Ridiculous price I know
    but what Leica accessory isn't?
