[APML] Focusing OM-1 (Was:Film Images)

[Alan Voetsch <alanv12952@yahoo.com>]

Stuart,

I thought it might be beneficial for me to jump in here and pass on the
same advice to you that John Mirtle gave to me last year. He
recommended the Lumicon 6X Critical focus scope. I think it still sells
for about $20. Easy to use and because I use it with my Taurus, the
focus is easily repeatable and only needed to be done once. Your
mileage may vary, but it is an inexpensive option.
