Advertisement Posted August 26, 2013 Posted August 26, 2013 Hi christianpsu, Take a look here Dead pixel? on a week old Leica M. I'm sure you'll find what you were looking for!
jaapv Posted August 26, 2013 Share #42 Posted August 26, 2013 Why would that not be safe? Of course it is. Link to post Share on other sites More sharing options...

Berlinman Posted August 26, 2013 Share #45 Posted August 26, 2013 My Leica M is back from Solms and the dead column is fixed. I have two questions: Why causes a dead pixel a complete black column ? Why is the black column not visible in every picture. Could it be, that the dead pixel causes the black column only if the sensor is hot (longer use of LV) ?

Olsen Posted August 26, 2013 Share #46 Posted August 26, 2013 Every Nikon DSLR I have ever owned had multiple dead pixels. D1...D2H...D2X... And a D40. None on the X1. Purely random chance IMO. None of my Canon 1Ds, IDs II nor 1Ds III - ever - read my lips - ever - had one single 'dead pixel', red or green or any sort of 'line' - ever. Despite being carried - many times across continents in airplanes in heights up to 40.000 ft. My M8 had the problem. I sent it to Leica who fixed it. I still have my M9 - which I have never experiencing the Red Line Problem with - although I hear others have. That said: I will not - not buy the new M(240) before this line/dead pixels issue is solved. Regardless of what cosmic radiation might do to digital cameras, Canon has solved it.

jaapv Posted August 27, 2013 Share #47 Posted August 27, 2013 Advertisement (gone after registration) Have they? I always wondered why those DSLRs were so heavy - it must be the thick layer of concrete shielding them.... Let me google that for you FYI: None of my Leica digitals ever - read my lips -ever- had it, despite being carried many times across continents in airplanes at heights up to 40.000 feet.

bocaburger Posted August 27, 2013 Share #48 Posted August 27, 2013 All my digitals (starting with a D30--not a 30D, I mean the 3MP D30) have been up on scores of high-altitude flights. Even before I touched my M8 and M9 they had both flown from Solms to Popflash in California and then back clear across the USA to me. ALL my digital cameras have had dead pixels. NONE of them have ever (yet) developed a line of any sort. That (lines of dead pixels) sounds like sensor defect to me, not the result of cosmic radiation.

jaapv Posted August 27, 2013 Share #49 Posted August 27, 2013 The line effect has to do with the way the sensor is read out, but is caused by a single dead pixel. Link to post Share on other sites More sharing options...
bocaburger Posted August 27, 2013 Share #50 Posted August 27, 2013 Is there some particular IQ advantage to having the sensor read out that way that outweighs the inconvenience of dealing with dead pixel lines? I ask because it seems other brands don't read that way, because they don't get dead lines. And why do some dead pixels in the Leicas produce a line but others don't? I'm sure there are some dead pixels in my 4 yr old M9, but no line (so far)? Link to post Share on other sites More sharing options...
Daniel Beacock Posted August 31, 2013 Share #51 Posted August 31, 2013 Thank you Daniel. I was hoping to get an image which you think "Does not have the line" as well, to see if I can tease it out. Bingo! Found the problem I was having and I can now replicate it as I know exactly what it is. I cannot believe the one setting I did not check when I was trying to replicate it when it first happened was the ISO setting! I didn't even think of it as I rarely change it from base, on that day, though, I was using it on auto and the last few pictures of the day were all at 640. If the ISO is set to 640 the line appears, any other ISO level and there is no sign whatsoever, even when you tweak the hell out of the file! Can anyone else replicate this problem? Seems odd that is is just that level, but I've now tested all other ISO levels and all others are fine. Intrigued to know if it happens to anyone else.

Berlinman Posted August 31, 2013 Share #52 Posted August 31, 2013 Hi, I checked my photos. The line is only at ISO 320 and 640 ! But now since the camera was in Solms it is fixed. Link to post Share on other sites More sharing options...
Daniel Beacock Posted August 31, 2013 Share #53 Posted August 31, 2013 More on this. Using tronds screen photo check suggestion I'm getting 5 'bad' columns showing up, but none of them correspond to the single bluey-green column I'm getting at ISO 640. When I use 640 to take a shot of my monitor the fault appears as a new line altogether. I don't think the two issues, (in my case at least), are related. Think I will drop Solms a query on this.

Daniel Beacock Posted August 31, 2013 Share #55 Posted August 31, 2013 Sometimes it's looking like this. Not very good for a 6200 Euro Camera.[ATTACH]392130[/ATTACH] Ralph, can you let me know if the blue line in your picture corresponds to one of your 7 bad columns? Also what was the ISO out of interest? Link to post Share on other sites More sharing options...
woopie Posted September 1, 2013 Share #56 Posted September 1, 2013 Ok in conclusion, dead pixel is tipical of Nikon, Canon, Leica, etc... But since Leica costs more than the others, Leica should buy and sell to us in her cameras sensors with less tolerance... But, What we paid more for? If I (Leica) think to be the best, make advertising as I were the best, priced my stuff as I were the best.... Why when I give answer to my customers say... Everybody has the same problem? They forget to be the best? When you're the best, priced the best, cannot say only sorry.... You must give an answer graduated to your price... If you find a toilet broken at Ritz Paris..or at Super8 of Detroit... Your reaction - I imagine - should be different... But both are toilets and both could be broken...and both I use to do the same thing... So Leica wake up! because I'm listening a lot of compliance about you... and some of your customer buys your stuff to take pictures and not to send their cameras or lenses ( issues on 50 Apo cron...) on vacation in Solms.... Wake up... Or you'll become the sleeping beauty with no princes to do it for a good end... Marcello Link to post Share on other sites More sharing options...
Urmelchen Posted September 1, 2013 Share #57 Posted September 1, 2013 Ralph, can you let me know if the blue line in your picture corresponds to one of your 7 bad columns? Also what was the ISO out of interest? Yes the line coresponds to a mapped out column. It's visible sometimes. My M have 7 mapped out columns. Have to call Leica support soon. I want a mapping free sensor for 6000 Euro. On cmos sensors only bad pixels are ok but not bad columns. Welcome, dear visitor!

Urmelchen Posted September 1, 2013 Share #59 Posted September 1, 2013 If you want an unmapped flawless sensor make that16000 Euro.... And it won't stay that way either.... Huh? I'm talking about remaped lines not pixel! My Canon 5D MarkII don't have any remapped lines. Maybe pixels but not whole lines! This is what i'm talking about. It's mystic why Leica have to remaps lines. on a CMOS chip. Link to post Share on other sites More sharing options...
Berlinman Posted September 1, 2013 Share #60 Posted September 1, 2013 Daniel, I got no detailled answer from Solms, what the problem was... but their first reaction was, that the problem is a "hot" pixel. Link to post Share on other sites More sharing options...
