I'm happy to find this site, great information on lens repair. I mostly work with Rangefinder lenses, but with instructions available for these SLR lenses- in my comfort zone.
I've been using Nikon SLR's since 1978 or so, Nikon RF's since 1996. For digital I use a Nikon Df, Leica M9, Leica M Monochrom, and Leica M8. I have a good set of Nikkor lenses in F-Mount, Leica mount, S-Mount, and Contax RF Mount.
