leicatech Posted March 12, 2017 Share #1 Posted March 12, 2017 Advertisement (gone after registration) Hi everyone! I picked up a second hand M240 a couple of weeks back and have been loving it ever since. I just went out to edit some photos today and I noticed a horizontal line of what look like dead pixels that are in many of my photos. They don't seem to be in every photo from the session though. It's deeply saddening to see this issue with a camera I just bought. I'm not sure if it's a sensor issue or a memory card issue. Does anyone have any additional info on the matter? The line is above the center of the photo and mostly on the right side of the image. Thanks! Images - http://imgur.com/a/3h6Dc Quote Link to post Share on other sites More sharing options...

arichter Posted March 12, 2017 Share #3 Posted March 12, 2017 My M262 is with Leica NJ for 3 weeks now for the same issue. They had not answered my email with example pictures, and I just sent the camera in. Quote Link to post Share on other sites More sharing options...

They had not answered my email with example pictures, and I just sent the camera in. Was the issue consistent on your M262? I haven't had it happen since this morning. I've also switched to another memory card and haven't had the issue return. Quote Link to post Share on other sites More sharing options...
Exodies Posted March 12, 2017 Share #5 Posted March 12, 2017 Wasn't there talk of this happening at particular ISO settings? It's usually a dead pixel which Leica will treat with software. Quote Link to post Share on other sites More sharing options...

lct Posted March 12, 2017 Share #7 Posted March 12, 2017 Advertisement (gone after registration) [...] The line is above the center of the photo and mostly on the right side of the image. [...] It is visible on the left as well (pic). Looks like a dead pixel column running the entire length of the sensor. Can be mapped out in firmware but you'll have to send in the camera to Leica.

sblutter Posted March 13, 2017 Share #8 Posted March 13, 2017 You can touch up those client pics easily in PS - but yep, back to the factory it is. When you do get it back, once you're confident the 240 is reliable (no probs here ever) - you'll love it Hope you have a back up camera & can keep working PS: Nice shots!

arichter Posted March 13, 2017 Share #9 Posted March 13, 2017 Was the issue consistent on your M262? I haven't had it happen since this morning. I've also switched to another memory card and haven't had the issue return. For me it was not happening every time too. But it was at ~100% when a shot was taken when the previous one was still writing to the buffer (red light flashing). I wonder if yours is the same. I am not sure if it is the sensor or something else but when I called Leica they said my camera was in repair. 1 Quote Link to post Share on other sites More sharing options...

I am not sure if it is the sensor or something else but when I called Leica they said my camera was in repair. That's interesting. I just tried that now and haven't been able to reproduce the issue. I've also taken another 20-30 shots over the past couple of days with a new memory card with no issues. Quote Link to post Share on other sites More sharing options...
mmradman Posted March 14, 2017 Share #11 Posted March 14, 2017 From memory it is not horizontal but vertical line that signifies dead pixel, usually at ISO640. I know, my M240 exhibited this (2014) and it made visit to its birthplace, works perfectly since. Quote Link to post Share on other sites More sharing options...
pico Posted March 14, 2017 Share #12 Posted March 14, 2017 You can touch up those client pics easily in PS - but yep, back to the factory it is. sblutter and I are likely in agreement. My difference is that when one of my M9s show flaws, I have a PS action that cures the flaw, hands-off, and in batch when necessary. My expectations of a perfect sensor have evaporated.

Oh interesting. Can you talk more about that PS action and how I can use or create one for this case? Thanks! Quote Link to post Share on other sites More sharing options...
leicatech Posted March 15, 2017 Author Share #14 Posted March 15, 2017 (edited) I also notice it's not just a single pixel column, at least for the first photo I posted. It looks like 3-4 pixels for the height. Please see these photos: http://imgur.com/a5Jb2xm http://imgur.com/XbUZtak I also still haven't been able to reproduce the issue with the new memory card.

I am not sure if it is the sensor or something else but when I called Leica they said my camera was in repair. I've been having this problem on an M-P240, and I think it might be when writing to the buffer like you, when the red light is flashing. I've been noticing that in my continuous series I get it a bunch, but when I look at photos I know I took slowly, just one at a time with plenty of time in between, I don't see it. I'm going to do some tests to see if this is really it. I'm glad you noticed that, I never would have Thank god for the spot healing brush in Photoshop!
