Tele/Wide adapter question

[Ken Smith]

I have a pair of the auxillary Yashica lenses for my GSN and just discovered a little fungus inside the lense. Anyone know how to disassemble the adapters to get access to the inside elements?

Figured it out on my own - fungus gone. For anyone who has one with internal fungus or just want to clean internal haze: Remove the 3 set screws. The rear optic assembly screws out, but since its seated tightly, it's much easier to remove if you mount the lens on your camera, then unscrew the forward half. Once the glass is clean you can re-assemble in hand.

I have this same problem, a layer of haze inside the tele-lens. Someone told me that some elements are glued, so it may be problematic to un-glue them and glue them again with precision.
Can you please confirm that there is no need to separate glued lenses?? If you answer is positive, I may give it a try ...
Thanks in advance

With my set, the haze/fungus was limited to the glass surfaces and was easily cleaned off. All bright and clear now.
