Advertisement Posted November 7, 2017 Posted November 7, 2017 Hi fsprow, Take a look here Clear/UV Filters on M lenses?. I'm sure you'll find what you were looking for!
6bit Posted November 9, 2017 Share #22 Posted November 9, 2017 Has anyone mentioned Roger’s testing/experience at Lensrentals? His big take away was protection for the front element. I use one on all of my leica lenses. At night under lights I will remove it to be sure. I also hardly ever use one with my noctilux .95.

Bill W Posted November 9, 2017 Share #23 Posted November 9, 2017 I have always used one and saved a lens a couple of times from disaster. Quote Link to post Share on other sites More sharing options...

Mute-on Posted November 9, 2017 Share #25 Posted November 9, 2017 (edited) I've used a clear/UV filter on all my lenses for the last 25 years, day or night. I've never experienced any unwanted flare, glare or reflections. Of course, since I've never shot my lenses naked, I have no idea what difference the filters actually make to the final image. Still, I'm ok with that. It's a trade-off (if any) that I'm happy to make to keep my lenses protected and scratch free.

strohscw Posted November 9, 2017 Share #26 Posted November 9, 2017 I never use UV filters, the only protection for my lens is the lens shade. Quote Link to post Share on other sites More sharing options...
Bison Posted November 17, 2017 Share #27 Posted November 17, 2017 Advertisement (gone after registration) I personally never use filters unless I'm around blowing water (especially salt water) and carry a few identical UV filters to change out in that circumstance when they are dirty/wet. Have been doing this for 30+ years with no ill effects. This was my practice, too. Not with multiple filters, though. I generally did not use filters, but instead, I relied on the lens hoods for protection. If around sand, surf, salt water, though, I'd mount Leica filters on my glass for extra protection. Nowadays, I have one on my primary lens (35 'cron ASPH) and I have one in the bag for my 90 'cron, but I don't leave it mounted. I've never noticed any degradation in my normal process, at all.

lct Posted September 1, 2022 Share #31 Posted September 1, 2022 (edited) Flare is a part of photography folks. Great feature if you're interested in dreamy looks. Nice examples with a Summicron v3 here (link). Superb lens indeed, was my first Leica lens in the seventies but dreamy looks were not my cup of tea so i sold the v3 and got a v4 instead. Was an early model with "tiger paw" focus tab then with more contrast than v3 but also less flare indeed. The coating of the lens was blueish then and became brownish with a bit less flare lately. Been my second copy of the v4, a superb German made with concave focus tab i'm still using today. I got also a v5, with built-in hood, that has the same IQ. All this so say that all lenses have not the same character fortunately. If you want a lens with the least possible flare, better choose a Summilux 50, asph or pre-asph. Or a Zeiss lens, Sonnar 50/1.5 or Planar 50/2. Edited September 1, 2022 by lct 1 Quote Link to post Share on other sites More sharing options...

I've also seen it on 90mm Elmar where the inside of the lens tube behind the optics was shiny - flare looked very similar. On the 90 was cured by adding a flat-black liner to the lens tube. But I've encountered similar central flare with M version 2. 3. & 5 Summicrons, and R 50 Summicrons as well. (A few times even on the "flare-resistant" 50 mm Summarit 2.5.) They are still some of my favorite lenses - just have to learn the lighting conditions that cause it and avoid them. The worst flare I've had was with a 50mm Canon 1.4 SLR lens - before multicoating.

This means bad coating No. Lenses flare, some more than others. The most flare resistant ones I have used are the new CV 40mm 2.8, and any of the Zeiss ZM lenses. The Zeiss coatings are very good. You can lessen the strength of the flare by not using a filter, but in many circumstances it will still be there. 1 Quote Link to post Share on other sites More sharing options...

Having flare when the sun is in front of me or coming from side I can understand and avoid, but as it is seen from the images I have attached the sun was behind me and covered by clouds, despite of this I got white spot in the center which I can’t call it normal, it is unpredictable… Quote Link to post Share on other sites More sharing options...

Looks like 'cloudy bright' with quite a high sun. So the sky will be effectively a large diffuse illuminator and could well cause veiling flare if a darkish subject (under the trees) is being taken. The 90/2.8 'thin' Tele-Elmarit I had used to flare in a similar way under such conditions and the lens is well known for doing so. Quote Link to post Share on other sites More sharing options...

The 90/2.8 'thin' Tele-Elmarit I had used to flare in a similar way under such conditions and the lens is well known for doing so. You're referring to CVS (central veiling flare) i guess. I can't seem to see this in the OP's pics above. At least not in the first one i can reproduce at will. Perhaps in the second one (priests) but i don't see it clearly. I can reproduce CVS as well but less easily. In my modest experience CVS tends to appear at small apertures mainly so i would avoid smaller apertures than f/11 personally. BTW the Summicron 50/2 apo did suffer from CVS at its launch and Leica fixed the issue in 2015 or thereabout. Not to say that the 50/2 apo is flare free though. Lenses as i like them are not sort of sunshades protecting photogs against light reflections but when i need less flare i take a Summilux 50/1.4 asph or pre-asph or a Sonnar 50/1.5 preferably. FWIW. 1 Quote Link to post Share on other sites More sharing options...

Before you go any further - and pardon if this sounds like calling IT help where they say 'have you turned it off and on again?' - make sure your lens doesn't have a finger print on the back element (lens mount side) nor on the front on the lens or filter. Also, it does not hurt your lens to not have a filter on it! They only are necessary if you are in a dirty environment - windy/dusty/by the beach/raining etc. So u could try w/o a filter.
