Do you have information on the old Mamiya Twin Lens Reflex (TLR) cameras?
Not much. My collecting interest has been limited to Mamiya 35mm SLR cameras, and this site is dedicated to them. I did recently acquire some old Mamiya TLR and medium-format information. Reprints of the instructions I have will be available on my Manuals page. Q: I have an old Mamiya 35mm that has fungus on the lens. Do you know how I can clean it? Nothing seems to work on that stuff! A: I have to assume you know how to disassemble your lens to get the glass separate from the rest of the mechanism. That done, make a small 50-50 mixture of hydrogen peroxide and regular ammonia, and wipe it directly (Q-Tips work well) on the fungus. It will literally melt right off! Follow up with clean water or a lens cleaner. Visit my How To section for more information.
