jmahto Posted June 19, 2019 Share #1 Posted June 19, 2019 (edited) Advertisement (gone after registration) Today I got the urge to clean my lenses. While doing so I thought a flash light test will be a good idea. All my lenses passed it, except my 40 Summicron-c! And this is one of my most used hiking/outdoors lens. Both on digital and film. I would not have suspected that it has haze just by going through the pictures. This is Flickr album from this lens. Welcome, dear visitor!

bayernfan Posted June 19, 2019 Share #2 Posted June 19, 2019 My 50 rigid summicron has light haze - it has little to no effect on image quality. In fact, I did a scene comparison against a modern Leica 50mm, and the contrast produced was virtually identical. Feel free to post a pic of the lens so we can see what we're talkin about.

lykaman Posted June 19, 2019 Share #3 Posted June 19, 2019 Hi, I'm not highly technical, but surely, depending on the Aperture Used and the actual Light situation the Haze will intrude on the taken image.. Link to post Share on other sites More sharing options...

Technically yes, but it might not be noticeable in most lighting situations. 1 Link to post Share on other sites More sharing options...

If the haze if heavier on the periphery (which I've seen), yes, the aperture used would certainly have an effect on image. A smaller aperture would result in an image with more contrast. Regarding the light source itself, I believe haze has the effect of scattering light rays, giving way to more internal reflections, which ultimately results in a lower contrast image.

That is my understanding, certainly some inconsistencies on a bright day shoot... Link to post Share on other sites More sharing options...

This is the pic. It is visible only at certain angle of light. Maybe it is not that bad. Hazy Welcome, dear visitor!

oldwino Posted June 19, 2019 Share #10 Posted June 19, 2019 I recently had a lens with very light haze cleaned. I was very happy with the images the lens produced, but the aperture ring was a little loose, so I sent it in for repair and cleaning. Man, what a difference! Noticeably better contrast in the cleaned lens, better color too. Have your lens cleaned. It’s worth it. It’s like getting a new lens back. 1 Link to post Share on other sites More sharing options...

Although, in my experience, the improvement is variable depending on where the affected element(s) is (are) located: the closer the hazy element is to the sensor (or film) plane, the bigger the loss of contrast - and therefore the improvement post cleaning. Haze (or any other blemish) on a front element doesn't look good but has little noticeable effect on the vast majority of pictures. Link to post Share on other sites More sharing options...
farnz Posted June 20, 2019 Share #12 Posted June 20, 2019 I don't mind haze and have acquired lenses with haze in the past to use for artistic effect. In my experience, haze can help produce low contrast pictures, which are useful where a scene has high dynamic range because the shadows are more likely to retain detail and the highlights are less likely to blow out. It doesn't always work and some scenes are certainly better with higher contrast lenses but I like to have 'different brushes' to use on the canvas. 🙂 Pete. 1 Link to post Share on other sites More sharing options...
Ko.Fe. Posted June 21, 2019 Share #13 Posted June 21, 2019 (edited) I had Canon 5 01.8 LTM with non removable by cleaning haze. If sun was into the frame edge it was affecting the whole image. I was given clean copy of this lens and no problems like with hazed one. I had Summar with removable haze. The images were much better after cleaning. Contrast reminded low because of no coating. With haze details were missing. Edited June 21, 2019 by Ko.Fe. Link to post Share on other sites More sharing options...
