Yep, beautiful pictures from a very good lens imo.

Hello,
does anyone know how to get to the rear elements of a Pentax K35/3.5?

Need to remove some fungus on one of the rear elements, but cannot get them out.

Thanks!

Try with some thick paper going underneath it, and blow some canned air through it some time.

Kram,
if it's the Yashica ML 28 that you want, I can help you with that - I don't use mine.
Let me know if I can help you with that one.
