My now complete Pentax-F prime collection!
Quote from agentlossing on May 30, 2022, 1:10 amI have a 50/1.7 F which has fungus on the back of both the front and rear elements. I'm trying to figure out if it can be opened up very easily to clean.

If it's anything like some of the vintage lenses I've opened, the rear elements are usually cemented together and cannot be opened easily. Sadly 🙁
The first few front elements have been easy on all the lenses I've tried. Once you get off the front inside ring that usually holds them in place with a spanner wrench then they just fall out from there, sometimes additional inside rings to loosen.
