Olsen Posted December 6, 2011 Share #21 Posted December 6, 2011 Advertisement (gone after registration) What utterly bullshit to blame the Red Line problem on astrophysics! What other camera brand got this problem? Along with my M8 and I have had a Canon 1Ds II and III, before that a 1Ds. These cameras never showed any red line problem. We just heard that RD1 even had an up grade fix. Link to post Share on other sites More sharing options...
Advertisement Posted December 6, 2011 Posted December 6, 2011 Hi Olsen, Take a look here M9 red line/dead pixel thread. I'm sure you'll find what you were looking for!
jaapv Posted December 6, 2011 Share #22 Posted December 6, 2011 We've had this discussion before on RFF. You simply refuse to believe all scientific evidence, articles by sensor makers, even NASA. <sigh> Are you going to suspend gravity now because your Leica fell on the floor and your Canons were never knocked off the table?

Olsen Posted December 6, 2011 Share #23 Posted December 6, 2011 ...sure, we have had this discussion before.... I shall not exaggerate the problem. By all means. I had the problem with my M8. I sent the camera to Solms, through the Norwegian dealer. It was returned and the problem never occurred again. I was charged nothing. - I have regular contact with the guy who bought it 2.hand from me. Nor has he had the problem reoccurring. So far, at least. Now this camera is five years old and has close to 20.000 exposures clocked. My M9, which I bought 2.hand and which had just as many exposures clocked as my M8 when I sold it, has performed perfectly. Even though I use it more frequently on high ISO settings. My wife and I are going on a cruise early next year. I intend to take my M9 along. Compared to my 1Ds III it is far smaller. I trust that my M9 will perform flawlessly.

BerndReini Posted December 8, 2011 Share #24 Posted December 8, 2011 Apples and Oranges. Canon uses CMOS sensors, the M9 has a CCD. My Phaseone back also has a dead pixel and Phaseone can usually recalibrate it remotely. As an aside, some of you may still be using Capture One and Phaseone's customer service is excellent and very responsive. Link to post Share on other sites More sharing options...
Olsen Posted December 9, 2011 Share #25 Posted December 9, 2011 But 'remapping', isn't that something that can be done by software? What is needed to perform a remapping? Well, it is not a screwdriver, is it? Or we could all have done it ourselves. Could we buy a software program to install on our PC/Macs that does the job?

jaapv Posted December 9, 2011 Share #26 Posted December 9, 2011 No - it is an in-camera function of the firmware.. Some cameras already offer this. But those are all CMos. I don't know, but I expect it is more difficult to implement on a CCD. Link to post Share on other sites More sharing options...
charles-k Posted December 9, 2011 Share #27 Posted December 9, 2011 Advertisement (gone after registration) With digital sensors there will be always be the possibility of dead pixels, and more frequently if you fly. Here is a very interesting link to This does discuss the issue, of dead pixels becoming more of an issue if you fly frequently. Link to post Share on other sites More sharing options...

MvMaltese Posted January 31, 2012 Share #29 Posted January 31, 2012 Amazing...never knew the connection between flying and dead pixels. Wonder what solutions are to this? Link to post Share on other sites More sharing options...
Pango Posted February 1, 2012 Share #30 Posted February 1, 2012 Yep, had it too. Camera duly sent off to Germany for re-map. The lens cap on and a 30sec exsposure sounds odd but worth a go. Can a firmware update fix this? Only Leica HQ know! If so, I'd have thought Leica would issue a user-fix to avoid the M brand becoming tarnised.

I don't know, but I expect it is more difficult to implement on a CCD. The vast majority of p&s cameras have CCD sensors. Is the problem common on them or do they deal with it differently than Leica does? Link to post Share on other sites More sharing options...
MvMaltese Posted February 1, 2012 Share #33 Posted February 1, 2012 Wonder if we should start flying with a leaded bag for camera. Would the walk-through x-ray scanner damage CCD as well? Link to post Share on other sites More sharing options...
Karim N Posted March 14, 2024 Share #34 Posted March 14, 2024 On 5/2/2010 at 2:04 PM, jaapv said: There is a trick that sometimes works. Put a lenscap on, expose for 30 or more seconds three times or more. Sometimes that will revive a dead pixel. This actually worked for me. I own a M9 and recently noticed a red thin vertical line at ISO 640 and above. I put on a lens cap, released the shutter at ISO 640 for about 45 seconds, did that 3 times. I repeated the same process at ISO 800, and ISO 1250, the red dead pixel line is completely gone. Also gone are a few random dead pixels I had noticed in dark images. Thank you Jaap! 1 Link to post Share on other sites More sharing options...
