I have recently acquired a Pentax ME Super which is working great.
I've just bought a Vivitar Series 1 70-210 zoom in pretty good condition, however there appears to be a bit of fungus on the rear of the front element. Nothing too serious, it is only visible at certain angles and doesn't seem to affect too much the pictures.
I would like to clean it however...
Does anyone know how easy it is to get at the rear of the front element?
