My only argument is that looking at the 40mm, it is in perfect shape. I understand that a visual inspection is not good enough, but considering Leica made it and there are no markings, I just thought it would be accurate:) Any thoughts on where I can go to find out how to do an optical alignment test via projection? :-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-:-: Sam Carleton, Contractor -----Original Message----- From: John Collier [SMTP:jbcollier@home.com] Sent: Monday, March 05, 2001 10:37 AM To: leica-users@mejac.palo-alto.ca.us Subject: Re: [Leica] Leica Focomat V35 alignment You are checking the alignment of the outside of the mount not the lens optical unit. Is there not a way of checking the optical alignment using projection? If I bend a filter ring on a lens it does not throw the lens out of alignment but it would fail your test.
