jpk Posted January 15, 2022 Share #1 Posted January 15, 2022 (edited) Advertisement (gone after registration) Hi, I didn't use my S for some time but had it serviced recently, so today I took some shots and noticed this kind of stripes I never saw before: Welcome, dear visitor!

Pieter12 Posted January 15, 2022 Share #4 Posted January 15, 2022 Interesting. I only seems to be present in certain areas, almost as if it were the texture of the material. Have you tried shooting something that is an even surface with even lighting and tone? Quote Link to post Share on other sites More sharing options...

It appears also in totally different pictures (with different ISO etc.), so I don't think it's a property of what is captured... Quote Link to post Share on other sites More sharing options...

tom0511 Posted January 24, 2022 Share #8 Posted January 24, 2022 So what was the problem? Sensor defect? 2 1 Quote Link to post Share on other sites More sharing options...
jpk Posted January 30, 2022 Author Share #9 Posted January 30, 2022 They said it's newton rings in the lens and I have to send in my equipment... Quote Link to post Share on other sites More sharing options...
Pieter12 Posted January 31, 2022 Share #10 Posted January 31, 2022 Which lens? My understanding is Newton's rings occur when two polished glass surfaces touch, so either something has moved in the lens or sensor or the rings were there all along. They shouldn't just show up after a while. Quote Link to post Share on other sites More sharing options...
jpk Posted February 7, 2022 Author Share #11 Posted February 7, 2022 The lens got the AF motor replaced recently, since that the rings occur... Quote Link to post Share on other sites More sharing options...
tom0511 Posted February 9, 2022 Share #12 Posted February 9, 2022 interesting, I hope you get it back and fixed soon Quote Link to post Share on other sites More sharing options...
jpk Posted June 23, 2022 Author Share #13 Posted June 23, 2022 Update: I was asked if I could send in test pictures so that they could verify the problem. I sent the pictures and waited again, until I called them a couple of weeks later and found the files were not forwarded. Sent them again, no answer since. Strange, as they first inspected the pictures, decided the banding comes from Newton rings and asked me to send in the lens. Quote Link to post Share on other sites More sharing options...
Leica_006 Posted July 9, 2022 Share #14 Posted July 9, 2022 Any update? I've also noticed the same thing in my images recently (I'm using a S 006 with a replaced sensor + the 120mm lens)? Oddly, for me, it happens more often above ISO 100 and in darker photos (especially the shadows) - see the example image, clear banding pattern in the shadows, but not in the highlights (that photo was shot at ISO 400). It seems like an electronics problem to me... specifically, when the sensor is photon starved? I never see this in photos where there are plenty of photons. Welcome, dear visitor!

Leica_006 Posted July 9, 2022 Share #15 Posted July 9, 2022 I decided to run extensive controlled testing and discovered a few patterns: This happens across all of my lenses (120mm, 70mm and 35mm). This is happens at all ISO settings (from 100-1600). This phenomena is not present in the first few pictures I take (immediately after turning the camera on). But, starts happening after I'm 15-20 pictures in (which makes me think it’s related to sensor heating). Once the phenomena starts happening, it seems to be more pronounced at higher ISO settings. Both of these images were shot at ISO 1600 at 1/60th of a second with my 70mm lens, within 2 minutes of each other. The only difference is one of them was taken earlier in a sequence of images (presumably, when the sensor was cooler). Welcome, dear visitor!

Leica_006 Posted July 9, 2022 Share #16 Posted July 9, 2022 Also, one last note. The "stripe pattern" is present across the entire image. It's just often easier to see in the shadows vs. the highlights. Welcome, dear visitor!

Leica_006 Posted July 9, 2022 Share #17 Posted July 9, 2022 Last, check this out... the pattern changes from image to image. Note: each of these photos were taken in sequence, a few seconds after the other. I initially thought there was a correlation with shutter speed... but notice two of the images are at 1/750th of a second... again, makes me think this is about temperature of the sensor, and maybe Newton rings with the sensor cover glass (as it warps with heat)? no idea? but this has ruined a few amazing moments/photos for me recently (that I won't be able to get back) 😕 Welcome, dear visitor!

Sarnian Posted July 9, 2022 Share #18 Posted July 9, 2022 You have a good amount of data to show Leica. They must surely replace your 006 free of charge after seeing your images! Quote Link to post Share on other sites More sharing options...
Leica_006 Posted July 10, 2022 Share #19 Posted July 10, 2022 I've sent a note to Leica - New Jersey, I'll report back with what I hear/and my experience getting this resolved. 1 Quote Link to post Share on other sites More sharing options...
Stuart Richardson Posted July 10, 2022 Share #20 Posted July 10, 2022 (edited) Looks like gaberdine...very odd. It does sound likely that there is something going with the electronics as they heat up. Or maybe some sort of electrical interference? I wonder if that could also be what is changing the size and frequency of the banding...kind of like static in an older style television with an antenna. This kind of difficult to trace error can creep in with older audio equipment when a component on the circuit board like a capacitor or resistor starts to fail. Hopefully this is something Leica can find and address. Edited July 10, 2022 by Stuart Richardson Quote Link to post Share on other sites More sharing options...
