DaveEP Posted June 8, 2007 Share #1 Posted June 8, 2007 Advertisement (gone after registration) I was out this evening playing with B+W 092 and 093 IR filters. I was taking shots of the same scene with both, trying to figure out the characteristics of both, and which (if either) I preferred. These are only test shots, so not intended to be 'arty' However, on most of the longer exposures I am noticing an un-welcome virtical line in the RAW file. I have seen this line (or a line in roughly this position) before, but it's not in every shot, and in fact is rarely there. The last time I saw it was a shot take a month ago at ISO 640. I assumed it was maybe an ISO related issue, but these are all at ISO 160. The line goes from top to bottom of the shot. Any ideas? Should I be concerned, and be sending it body back to the black hole of Solms (it already needs to go for the Pwer switch half press issue). I don't recall ever having this issue on Canon.... so is it normal and 'to be expected' on an M8, or should this puppy go in for a service? First the full frame, then the 100% crop of the top right of the grave stone. No processing other than white balance. Link to post Share on other sites More sharing options...

cbretteville Posted June 8, 2007 Share #2 Posted June 8, 2007 Dead row of pixels. You need to have the sensor replaced. Sorry, - Carl Link to post Share on other sites More sharing options...
DaveEP Posted June 8, 2007 Author Share #3 Posted June 8, 2007 Dead row of pixels- Carl Thanks. would this normally only show up on long exposures? It's not normally a problem for regular stuff.... Link to post Share on other sites More sharing options...
cbretteville Posted June 8, 2007 Share #4 Posted June 8, 2007 David, I don't know. I did recognize it from past posts so do a forum search and I'm sure you'll find something. - C Link to post Share on other sites More sharing options...
DaveEP Posted June 8, 2007 Author Share #5 Posted June 8, 2007 I just did a quick test. This line appears on all shots of 1/8 second or longer ..... For ALL shots faster than 1/8 there is no line, which is why I rarely see it. Bummer.... Sounds like a second M8 is needed sooner rather than later if I don't want to be without it...

RMF Posted June 8, 2007 Share #6 Posted June 8, 2007 I 'do not' believe it is a dead row of pixels. This problem has seemed to make itself known with 1.02. I have the same line at 640 iso and above. I hope that Leica will take a look at this issue and hopefully fix via firmware.

DaveEP Posted June 8, 2007 Author Share #7 Posted June 8, 2007 Advertisement (gone after registration) What makes you think it's firmware and not a hardware failure ? I am willing to accept it's firmware, but what evidence do you have? If it's a firmware problem, surely every one would have it to some extent or other. If not, then it has to be camera specific, which means hardware, not software (firmware). Link to post Share on other sites More sharing options...
