IamTheDistance Posted December 31, 2018 Share #1 Posted December 31, 2018 Advertisement (gone after registration) Happy New Year to everyone. I'm having some problems when shooting with the Sun in front of me. I'm using a M10 with 35mm f/2.4 summarit and original hood. In the image appears a perfectly straight line which seems to be the hood blocking the light? Or maybe a sensor error? Someone with this problem? I tested today without hood in a different situation and the problem is still there. I searched on the Internet but I couldn't find the answer. Also my English skills are low... Thank you!

Advertisement Posted December 31, 2018 Posted December 31, 2018 Hi IamTheDistance, Take a look here M10 sensor error or hood blocking the light?. I'm sure you'll find what you were looking for!
Chaemono Posted December 31, 2018 Share #2 Posted December 31, 2018 I‘m in the distance, so I can’t tell for sure. Do you get the perfectly straight line with other lenses? My English skills are low, too. 1 Link to post Share on other sites More sharing options...
Gobert Posted December 31, 2018 Share #3 Posted December 31, 2018 This is not because of the hood. The line is quite straight. Link to post Share on other sites More sharing options...
jankap Posted December 31, 2018 Share #4 Posted December 31, 2018 Agree. Straight and the border is sharp. The lower part of the picture is normal. What about, if you keep the camera upside down or without a lens? It seems, there is something wrong in the camera. Jan Link to post Share on other sites More sharing options...
M11 for me Posted December 31, 2018 Share #5 Posted December 31, 2018 (edited) Tell us if your error is reproducable with different lenses? Edited December 31, 2018 by Alex U. Link to post Share on other sites More sharing options...

jaapv Posted December 31, 2018 Share #7 Posted December 31, 2018 Advertisement (gone after registration) I've seen this one before. I think it is veiling flare being cut off by the baffles inside the body. Link to post Share on other sites More sharing options...
a.noctilux Posted December 31, 2018 Share #8 Posted December 31, 2018 I have this kind of "baffling no-flare" in contre-jour images from different digital Leica M and with some lenses with or without hood. That may come from some sort of baffle in the M body: maybe the baffle just after the shutter mechanism. In relation with the sun position and framing, this is irregularly and mostly when the sun is just outside of the frame. I wanted to sort it out by turning the camera upside down, and the "no flare" is always at the top of the final image. Link to post Share on other sites More sharing options...

SMAL Posted December 31, 2018 Share #10 Posted December 31, 2018 Looks more like a leak somewhere in the Leica Body. A flare would have a soft edge and not that hard line. Link to post Share on other sites More sharing options...
jip Posted December 31, 2018 Share #11 Posted December 31, 2018 It's the lens flare that gets cut of by a straight line inside the camera body Have seen this on: M240, M9, M10. 1 Link to post Share on other sites More sharing options...

You mean this issue is so prevalent but occurs on and off, under certain conditions, sporadically? Man, that just stinks. I was going to get an M10-D but it doesn’t have an LCD screen either. vor 2 Stunden schrieb a.noctilux: ...to compare, a couple of minutes later no trace of the “non-flare” no trace of the "non-flare", so the setup is sensible to "angle of the sun" Only “a couple of minutes later,” well, what do you know? Here is what I’m going to do. I’ll get two M10-Ds and always take identical pictures with each. It’s highly unlikely that this issue will occur in the same picture with both. Worse comes to worse, I’ll just turn the cameras upside down before releasing the shutter. Thanks for the advice. Link to post Share on other sites More sharing options...
pedaes Posted December 31, 2018 Share #13 Posted December 31, 2018 Getting back on topic, surely OP can easily check by taking shot with sun behind.If ok, then most probably what is suggested by jaapv and a.noctiux. Link to post Share on other sites More sharing options...
jaapv Posted December 31, 2018 Share #14 Posted December 31, 2018 Here we have the same question - with the same answers... 1 Link to post Share on other sites More sharing options...
adan Posted December 31, 2018 Share #15 Posted December 31, 2018 (edited) I need to save this diagram - the question comes up every 6 months or so. No lens hood can be perfect, since a lens has dimension (diameter). A bright light (the sun) just outside the picture may light up the floor of the camera chamber, producing flare. The sensor (or film, for that matter) is set back in a short (~3mm) tunnel in which the shutter operates. That tunnel will protect or shade a thin strip of the sensor from the flare, cutting off the flare in a straight line. The lens projects the sun and scene "upside down" - therefore the flare and the dark line formed in the bottom of the camera appear in the top of the final picture. Welcome, dear visitor!

a.noctilux Posted December 31, 2018 Share #16 Posted December 31, 2018 Thanks Andy. Clearly explained as usual 👍 So for me nothing can be done on our beloved M, or just some degrees move as I experienced from M "with screen" (after chimping or LV use).

SMAL Posted December 31, 2018 Share #17 Posted December 31, 2018 (edited) @adan thanks for the explanation. You always learn something new. So this basically could happen with every mirrorless with a short flange distance? I luckily haven’t experienced such a line yet.

pico Posted December 31, 2018 Share #18 Posted December 31, 2018 The Leica lens shades are compromises which favor portability and quick use of the lenses. To make a shade that is very effective would require owners to adjust the shades for various circumstances and that is not the Leica Way. Link to post Share on other sites More sharing options...

adan Posted January 1, 2019 Share #20 Posted January 1, 2019 (edited) 5 hours ago, SMAL said: So this basically could happen with every mirrorless with a short flange distance? In theory. But I notice that, for example, the Sony A7 and Fuji XT-1 don't have a flat floor to their chambers - they have a curved "valley" or "smile" that follows the line of the lens contacts. That will make "spill light" reflect forward from around the sensor, rather than up and back from the floor. The Nikon Z7 (and presumably the Z6) don't have much of any floor at all - just a huge flat forward-facing "wall" around the sensor: https://goo.gl/images/Zw9DBZ The Leica Ms are sort of stuck with the flat floor, as it's the space that holds the "classic" backwards-pointing meter sensor that's been used since the M8. Plus, of course, the shorter the flange distance, the less area in the camera to possibly reflect light (it'll tend to fall inside the back of the lens barrel, rather than into the camera). Same for, say, a 35 cron/lux ASPH - the lens elements extending deeper into the camera mouth will tend to "contain" any spill light - there may be lens flare, but it won't get cut off to form the line: https://goo.gl/images/iNx7TZ The 35 Summarit has a rear element quite far from the sensor, in a funnel, (compare to Summicron in link above) thus spreading around more spill into the camera itself: https://goo.gl/images/bHYXNy As it happens I was just yesterday shooting a friend's artwork. Which has an extremely shiny urethane coating over the wooden art. To avoid reflections, we had to shoot it in backlit shade, and I had a lot of flare trouble using a 35 Summarit - with a hood. Kept checking the lens for fingerprints and such, it was so bad. Answering this thread, I suddenly realized it was likely "floor reflections" but without the shadowing, since I was shooting verticals (and thus the spill from overhead sky was flaring off the end walls, not the floor of the camera). Fortunately it is easier to fix the flare "gradient" than touch out the mirror-clear reflections of the surroundings I would have had otherwise. Welcome, dear visitor!
