mahakalaka Posted August 2, 2011 Share #1 Posted August 2, 2011 Advertisement (gone after registration) Hi all! I recently received my 35mm Summilux ASPH V2 and just developed the first two rolls of film I shot with it. To my surprise, a lot of the images have a strong vignette in them, even lots that where shot at around f8. I've used a B+H yellow filter (which I use most of the time on all my lenses) and the standard lens hood that came with it. I'm not really sure what to make of this? Everything I've read about this lens says that it does not vignette much. I never got even close to the same amount of vignetting from my old 35mm Summicron V3 before, which I've used for years. Any thoughts? I'm feeling kind of bummed right now because I have been eagerly waiting for my coppy for almost a year now, plus I had to sell a lot of stuff I really liked to be able to fund it. The pictures that did not vignette look nice though. Thanks, Maximilian Link to post Share on other sites More sharing options...

lct Posted August 2, 2011 Share #2 Posted August 2, 2011 ...Any thoughts?... Yes remove the filter and try again. Link to post Share on other sites More sharing options...
mahakalaka Posted August 3, 2011 Author Share #3 Posted August 3, 2011 Thanks, but two of the pictures I took, where taken with a UV filter and they show vignetting too. Leica can't possibly expect people to not use filters, right? And these are both high quality filters. Well I'm taking it back to my dealer today to talk it over with them.

hoppyman Posted August 3, 2011 Share #4 Posted August 3, 2011 You certainly should not be seeing strong vignetting at f/8. The published figures show about the same level at f/5.6 as the previous model (~50% in extreme corners). Some vignetting is normal and not necessarily noticeable. It is somewhat dependent on your subject, lighting conditions and developing as to whether it is visible at all of course. Perhaps you could provide a link to an example as it may make it easier to offer suggestions? I suspect that there is another factor involved here, especially when you are only see the effect sometimes.. What brand of filters were you using? Most do not fit within the externally threaded hood. Did you mean B+W? Those do not fit within the hood on my lens. I had to get a Leica branded UV for mechanical protection on my lens. Incidentally the ring of that one is significantly deeper than the B+W slim ones. A single filter should not be causing any mechanical vignetting. What type of film and how has it been exposed and processed/printed? This lens works perfectly on my M9 but the firmware in that does compensate to some extent for natural vignetting due to the sensor/lens relationship with wider lenses. So I cannot directly compare my examples to yours. Nothing like 'strong vignetting' that you are describing though. Link to post Share on other sites More sharing options...
mahakalaka Posted August 3, 2011 Author Share #5 Posted August 3, 2011 Hi Hoppyman, Thanks for your help! Yes, I meant B+W, my yellow filter is "B+W 46 022 2x", it fits perfectly fine under the standard hood. I used one roll of Tri-X and one roll of FP4, both developed at my local prolab, both have vignetting. Here are some examples. Welcome, dear visitor!

lct Posted August 3, 2011 Share #6 Posted August 3, 2011 Thanks, but two of the pictures I took, where taken with a UV filter and they show vignetting too... It is a simple test to check if the filters play any role here. Link to post Share on other sites More sharing options...
Xmas Posted August 3, 2011 Share #7 Posted August 3, 2011 Advertisement (gone after registration) Hi Flip the back door up set the camera to B and see if you can see the filter or hood from the rear of the camera... Remove to confirm it is filter or hood. Try focused close up and at infinity. Vary aperture... Noel Link to post Share on other sites More sharing options...
mahakalaka Posted August 3, 2011 Author Share #8 Posted August 3, 2011 It is a simple test to check if the filters play any role here. Yes I understand, but I don't develop the film at home and I'm not too keen on blasting through a whole role of film and pay for developing, only for test. I guess I should do it anyways, but I'm thinking I'll take it to the shop and see if they can test it on a M9 instead. Thanks though, Maximilian Link to post Share on other sites More sharing options...

wattsy Posted August 3, 2011 Share #11 Posted August 3, 2011 Difficult to diagnose with only a few shots to go on but the first example looks like mechanically induced vignetting to me. It reminds me of the effect I get when I use my 50 Summarit with the 50 Elmar hood screwed in. In your case, I suspect that either the filter is coming in to play or the hood isn't seated correctly. The latter shouldn't be possible with the newer screw in hoods so I'd be suspicious of the filter. I've only had this lens for about a month and have only used it so far on an M9. As Geoff points out, it is difficult to draw any conclusions about vignetting when using the M9 because the camera has in-built compensation for vignetting but I haven't noticed that this lens has any great tendency towards vignetting (unlike, say, my 28 Summicron). If I remember I will shoot a few frames with the lens detection off (which won't remove all vignetting correction) to see if that makes much difference. When Leica finish rebuilding my new MP I will certainly be using the lens with film and will report back if I find anything relevant to this discussion.

hoppyman Posted August 3, 2011 Share #12 Posted August 3, 2011 However, keep in mind that the M9 does some processing (even with Raw files) that affects the level of vignetting. If you were trying to do the most rigorous testing you might shoot with your camera and transparency film (and look at them un-mounted). Keep this all in perspective though. The vignetting characteristics for this lens in that area look just like (those of) the previous model and lots of other lens of course. What is your reference standard? By that I mean it is easy to convince yourself that there is something abnormal if you don't know exactly what's normal I can make some extreme corners look darker with this lens and M9 with the right combination of light/subject on occasion (cloudy sky at sharp angle for example). But for hundreds of other shots I never saw anything. I don't even own a film M currently. I'll see about borrowing one and shooting a roll out of intrest. I think that you don't really want to go to the effort of this formal testing? Just shoot some more next time with no filter and no hood and some in similar conditions with another lens maybe.

mahakalaka Posted August 3, 2011 Author Share #13 Posted August 3, 2011 Thanks for the replies guys! Didn't get to the shop today to try it out on an m9. The filter and hood fit perfectly, but yeah I guess it must be the filter. Thing is I really want to use a yellow filter and I have no clew what other yellow filter to try? Again, my V3 Summicron with it's hood and a bunch of different filters, never vignetted at all like this. I got this vignetting with the Summilux on almost all outdoor shots, regardless of where the sun is in perspective to where the camera is aiming. Very strange... I'll let you know if I figure it out and I appreciate your help! Maximilian Link to post Share on other sites More sharing options...
lct Posted August 3, 2011 Share #14 Posted August 3, 2011 BTW you were using a B+W filter didn't you? How did you get to fit it in the Summilux hood? Link to post Share on other sites More sharing options...
mahakalaka Posted August 3, 2011 Author Share #15 Posted August 3, 2011 BTW you were using a B+W filter didn't you? How did you get to fit it in the Summilux hood? Yes, B+W 46 022 2x. Don't know why it doest'n work for you? My lens hood just screws perfectly on exactly like it does without the filter attached. It is an older filter though, not sure if B+W might have changed their dimensions on their newer filters? Link to post Share on other sites More sharing options...
lct Posted August 3, 2011 Share #16 Posted August 3, 2011 I was just curious as i still wonder what role this filter can play in your vignetting issue. Link to post Share on other sites More sharing options...
mahakalaka Posted August 4, 2011 Author Share #17 Posted August 4, 2011 UPDATE: Took it to the shop today and we tried it out on an M9-P, it showed considerable vignetting with and with out filters, on all apertures. It's on it's way back to Leica now. Thanks again for your input. Maximilian Link to post Share on other sites More sharing options...
lct Posted August 4, 2011 Share #18 Posted August 4, 2011 Thanks for sharing. Sounds like you can keep your filter. Link to post Share on other sites More sharing options...
