Page 17 from Nikon's Nikkormat FT3 (c. 1977) instruction manual. You can find .PDF copies of thousands of manuals for older cameras at Mike Butkus's Orphan Cameras. The .PDFs are shareware; $3 is the suggested donation. Beats spending $18 for a bad photocopy any day.
Featured Comment by Adam McAnaney: "Mike Butkus' site is an excellent resource. Here are a few other sites with classic camera manuals available for download:
DessauPhoto (Special-interest only: brochures for DDR (East German) cameras)."
Featured Comment by Ken Tanaka: "May I join the chorus singing the praises of this unsung hero, Mike Butkus?
"Although I am not an ancient camera collector (contrary to some evidence) last year I found a mint-condition Rolleiflex for sale, a camera I'd always wanted and an opportunity too good to ignore.
"But I knew zip about the correct care and feeding of my 50 year-old 'new' camera.
"Enter Mr. Butkus with a downloadable copy of the camera's original manual! Needless to say I was stunned and profoundly grateful to discover Mike's site. I am also still gobsmacked by the realization that someone could assemble such an enormous collection of extinct camera documentation. I bought a few other manuals for cameras I either never owned or owned long, long ago!)
"So here is my chance to publicly thank Mike for his efforts!"
