Cleaning a very dirty ALPA Altelar 90mm f/2.8

A dirty ALPA lens cleaned and inspected so it can return to practical use.

Some lenses arrive dirty rather than broken. This ALPA Altelar 90mm f/2.8 needed cleaning, inspection and a careful check of the optical surfaces.The job is mostly about restraint: remove what should be removed, avoid marking the glass and keep the mechanical alignment intact.After cleaning, the lens can be judged honestly for use rather than only for appearance.
