Hi Pete,
I have just successfully repaired a Minolta 24mm/2.8 following your instructions for the 28mm and have gotten a bit more ambitious now. I got a Minolta 50mm/2.8 Macro (for free) which has fungus on the inside of the rear element. How to remove the rear element? Is it possible when one is at the situation depicted in your picture PICT0600.jpg to directly "attack" the rear element without having to remove the trim cover and parts of the focus system? Many thanks in advance for your response
