How do I open up a canon ef 35-80mm zoom lens in order to clean dust and fungus from the lens elements? It's just an old lens, but I was wondering whether it was serviceable at all?
to clean the optics on a canon ef lens, remove the rear mount first being carefull to remove the screws on the mount pull gentle, there is a flex at rear, use a blower to clean to best poss, do not try to clean the front it is tricky.
