Crazing affect Images?

[e.besana]

Hi all,

A friend of mine recently gave me an SMC Pentax 50mm f2. Upon inspection of the lens I noticed significant crazing of the lens coating on both rear and front elements. I'm hesitant to purchase the adapter for this lens not knowing if it will even produce usable images.

Does anyone have any suggestions on how I might be able to "validate" the lens before I buy the adapter for it?

Thanks. -EB

Sounds like mould to me...

Sounds much like fungus to me too - I have a few lenses I was given that fit that description.
WHat I've found is that if it's not too bad they can be used for macro-ish work Ok, and for portrait or whatever, light seems to "scatter" and produce very soft "luminous" images (rather beautiful in their own way).
Don't know how you can test without buying an adaptor -- sorry

Maybe send a pm to BrianS.
He's the man for this sort of issue.
