Re: [Leica] V35 AUTO-FOCUS ADJUSTMENT

[Mary & Stan Kephart <kephartol@att.net>]

Hello Marc,

Thanks for your very clear instructions.  I've done everything you 
prescribe to a fraction of a mm.  Autofocus, however, is not right on 
target, and I find I have to check and adjust slightly for each print.  
Is this normal?

Mary
