Hello everyone. First time poster here! Great forum. I’ve been searching and reading for days and I’m impressed with the wealth of knowledge shared on these pages.
I just bought a 1953 Pacemaker Speed Graphic (I love it, by the way) and I’m dying to get shooting with it. Before I can do that it needs some work, so I’ve been cleaning it up. I have a few questions for you please.
I compared the Graflok back to the film holder. When I measure (with Starrett scale) from the flange to the glass surface on the Graflok back, I get a value roughly 1mm shorter than when I take a film holder and scale to the film surface. Is this correct? I thought the distances were supposed to be equal to insure focus correlation between the ground glass and the film surface.
Also, I disassembled the fresnel/ground glass assembly. I didn’t initially realize the assembly was two panes. One pane is plain glass and the other has a Fresnel surface. I am not sure I reassembled the surfaces in the correct orientation with respect to each (or with respect to the direction that light travels). Does the orientation matter?
Thank you for your time folks!
Regards,
Bravin Neff
