toona Posted June 18, 2010 Share #1 Posted June 18, 2010 Advertisement (gone after registration) M9 with latest firmware, 50mm f/0.95, iso 800, 1/30s exposure 0ev I noticed a vertical streak in this picture, but am not sure why. None of the other pictures on the card exhibited this problem. Is this a sign of things to come or just a one time anomaly? Thanks in advance.

Advertisement Posted June 18, 2010 Posted June 18, 2010 Hi toona, Take a look here What caused this artifact? m9, noctilux 0.95. I'm sure you'll find what you were looking for!
howard_cummer Posted June 18, 2010 Share #2 Posted June 18, 2010 Looks like it might be a dead pixel line. Had this on my M8 and it meant a sensor replacement. Not good news, I'm afraid. Does the line appear at higher ISO's? Link to post Share on other sites More sharing options...
toona Posted June 18, 2010 Author Share #3 Posted June 18, 2010 Mods--i accidentally posted this in another forum, but it was meant to be here. Please delete the other thread. I noticed this vertical artifact on one of my photos taken last night. It was shot in A-mode, auto WB, 800 iso, 1/30, handheld. The problem was only on this photo and not others on the card. Is this a symptom of a bigger problem or is it possible it's just this one time thing? I really hope it's an anomaly. Thanks in advance. Link to post Share on other sites More sharing options...
leicashot Posted June 18, 2010 Share #4 Posted June 18, 2010 I have experienced this and others like it with various cameras and usually its nothing to worry about, unless it happens more than once. This can occur from all sorts of reasons including temperature, electrical interference while processing from other devices and/or combination of frequencies nearby etc. I wouldn't worry at this point, but monitor it carefully.

Guest WPalank Posted June 18, 2010 Share #5 Posted June 18, 2010 M9 with latest firmware, 50mm f/0.95, iso 800, 1/30s exposure 0ev I noticed a vertical streak in this picture, but am not sure why. None of the other pictures on the card exhibited this problem. Is this a sign of things to come ......... Actually there are two vertical streaks in the picture. I don't think I have seen the lighter pink one before, but just do a search for vertical green band in the Forum and the reading will keep you up for days (M8 and M9). If it's a brand new camera, see what the dealer can work out, otherwise it will most likely have to go to Solms or NJ. There's a lot of talk about pixel mapping but it seems most people end up with a new camera or sensor replacement. I'm sorry for your troubles. I don't know what software you are using for Raw development but you can normally find the line in other images by playing with the Fill Light, Brightness and Contrast sliders.

therefromhere Posted June 18, 2010 Share #6 Posted June 18, 2010 Same here. My M8.2 is on it's way back to me from Solms with its THIRD sensor. The line looks a lot like you've got and was present in all ISOs but most visible in the higher ranges. I've been assuming the problem was inherent in all the M8s and had been considering upgrading to the M9... now I'm worried that Leica still hasn't figured this out...

Guest WPalank Posted June 18, 2010 Share #7 Posted June 18, 2010 Advertisement (gone after registration) Stupid question. Did you shoot the picture in Landscape Mode and then crop it to look like Portrait? The reason I ask is that the thin green line typically runs from left to right rather than top to bottom.

Jamie Roberts Posted June 18, 2010 Share #8 Posted June 18, 2010 This is not the M8 green streak artifact--not by a long shot. It's a dud pixel, and needs to be shipped to Leica. If it's brand new, I think the dealer should take care of it. That might still be a trip to Leica though. Link to post Share on other sites More sharing options...
Guest WPalank Posted June 18, 2010 Share #9 Posted June 18, 2010 This is not the M8 green streak artifact--not by a long shot. It's a dud pixel, and needs to be shipped to Leica. If it's brand new, I think the dealer should take care of it. That might still be a trip to Leica though. I'm not referring to the green blobs caused by a light source to close to the edge. I have had TWO sensors fail on both an M8 and M9 that produced a Green line that Leica attributed to sensor or sensor board failure. In the latter case Leica felt they could map it out if it was a "dud" pixel. Instead they found that wasn't the case and sent me a new camera due to a failed sensor board. If that's their way of saying dead pixel, so be it. Here's a thread with a similar issue: http://www.l-camera-forum.com/leica-forum/leica-m8-forum/79749-m8-green-streaky-lines-iso-640-a.html Again, am I the only one that sees TWO vertical lines, one pinkish and the other greenish blue. My feeling is the OP never saw the green one. Link to post Share on other sites More sharing options...
jaapv Posted June 18, 2010 Share #10 Posted June 18, 2010 No, William, you are not. But both of them look like pixel lines to my eye. Link to post Share on other sites More sharing options...
Jamie Roberts Posted June 19, 2010 Share #11 Posted June 19, 2010 No, William, you are not. But both of them look like pixel lines to my eye. To mine as well, hence my comment. @ William, yes, that's Leica's way of dealing with dead pixels: new sensor // board... at least it was with my M8. I hope they can map out the pixels now. Even better, I wish they had a program available that I could use to do it But if the OP searches "green band" or "green streak" or similar keywords for the digital M (as you suggested above), they're going to come up against the un-fixable M8 artifact, which the M9 doesn't suffer from at all...

toona Posted June 21, 2010 Author Share #12 Posted June 21, 2010 Thank you for all the responses. I've taken over 100 photos since noticing these lines, and none of the photos either before or after exhibit this problem. I called my dealer and he suggested I call Leica NJ, which I did. I can have them do an urgent assessement, but my inclination is to hold onto the camera and keep taking pictures. I'll eventually send it in, but i have too many trips coming up that i do not want to miss out on! Truly appreciate all the feedback. Link to post Share on other sites More sharing options...
John Bohn Posted July 2, 2010 Share #13 Posted July 2, 2010 I saw a similar fine white line in photographs made with one of my two M8 cameras. The line seemed to only show on images shot at ISO settings of 800 and higher. Hope that this helps you. Link to post Share on other sites More sharing options...
