Slight haze effects??

[ravid905]

How much of a problem is slight hazing on performance and what are the performance losses that may occur from it? Is cleaning possible, if it isn't too bad, and what would be the sort of costs involved in cleaning haze? We are assuming that it is slight and not heavy by the way.

Hello Kitty!

Visit this thread, look for the infamous "Hello Kitty Summarit test", $125 Summarit before and after a trip to Essex in New Jersey. $90 for the CLA and repair of a severely damaged front ring.

Thanks for that link. Reading on the KB site gave me the impression that it would soften the lens for sure, but me being a visual monkey, seeing the effects, makes it easier to understand.

The image is still pretty sharp, but the tone reproduction/contrast get screwed up really easily. If it gets bad enough, sharpness will suffer, but bad tones come first. Only an experienced person will recognise slight haze problems because you have nothing to compare it with.

Older glass makes really nice pics, but it has to be clean inside.

Copy and paste the link above. Photos 4 and 5 should match as the DR and rigid are the very same lens except for actual produced focal length tolerence may differ by a millimeter or two. #4 is low contrast and the appearance of the photo indicates there is some hazing internally.

Personally, I would have an older/old lens cleaned if you want to use it as a prime. 40-50
years is a long time and any haze will degrade the image. Re-lubing will make it smoother to use too. IMHO, you cannot really judge a lens unless it is clean.
