Nikkor-Q Auto 135mm f/3.5 optical cleaning

Optical cleaning on a classic Nikon telephoto lens, with inspection of glass, aperture and focusing action.

The Nikkor-Q Auto 135mm f/3.5 is a robust lens, but internal dust, haze or fungus can still make it worth opening.The optical path is inspected first, then the affected groups are removed and cleaned. The lens is checked again under light before final reassembly.With older Nikon lenses, preserving the mechanical feel is as important as cleaning the glass.
