  1. M10 sensor error at high ISO? at 3200 and at 12500 I get sometimes a vertical black line on top. Starting from left to right. At day or at low iso I do not see the line. serial 5191....
  2. Well, as an experienced M film user, you can imagine my disappointment ... I picked up my M10 in Sydney today and took about 100 shots at a family gathering with two lenses, a ZM Biogon 35/2 and a Summarit 75/2.5, shooting with auto ISO. On (I think) all the ISO 2500 images, I got horizontal lines that run all the way across the image. The lines seem to be 1 pixel high: see the first and third images I've uploaded. The files I've uploaded are 100% crops from the DNGs processed in Lightroom 5.7.1 (clicking auto exposure to bring out the issue, but it's visible on the straight conversions too). The same problem is also visible, in the same places, on the camera JPGs. Unsurprisingly, it's easiest to detect in shadow areas, but none of these was massively over or underexposed. It happened with both lenses (the Biogon hand-coded as a Summicron 35 and the Summarit auto-coding). Weirdly, I cannot find these problem lines at any other ISO sensitivities, and auto ISO picked a large range, from about 400 up to 10,000. There just seems to be something wrong with 2500. The other problem is a number of what appear to be hot pixels, which are not confined to ISO 2500. I've attached a shot (the second one, with the bottom of the beer bottle) that was taken at ISO 3200 and shows them fairly clearly. The camera is running firmware 1.3.4.0. I should add that I'm not at all new to Lightroom or digital generally. I've shot Nikon digital for many years. But this is my first digital M. So: have I got a dud body, and should I just take it back for exchange for a new one? All the best, Richard (I should also add that I've read this forum for a long time, and found it very helpful and informative, but I've never felt I had anything to add or any query to raise. I've searched the forum but can't find posts dealing with similar problems to the one I'm experiencing. The closest was about an M10 with horizontal banding, but that post did not seem to be about lines only 1 pixel high.)
  3. Hi all, I am still puzzled why my DNG files show no hot pixel but the corresponding JPEGs (option "DNG & JPEG...") do. I have read here that DNG files were stripped of such pixels automatically, but I can't understand why the camera does not do the same to the corresponding JPEGs... Does anyone know? Thanks
  4. Hey everyone, So my M8 that Id been waiting on arrived this morning from NYC, bought from a reputable dealer, and I have the opportunity to return it within a week according to their policy. The gripe is, though this thing is pristine and I hate to return it, I found a hot pixel Its easily seen at 640+, basically thought Id pick your brains as to whether this is something I can get fixed even though I bought it used, out of warranty obviously, or better to return it? Ive seen similar threads regarding the banding problems, that doesnt seem to be a problem with mine, its just the one pixel, which creates the vertical line situation I saw some of you had experienced, though the threads I read, you're cameras were under warranty and were fixed or replaced, Im in a different boat, so I thought Id see if anyone could enlighten. Thanks in advance! Bryan I attached a photo, test shot of a wall in my house, you can see the vertical line as well as the little red hot pixel, gets more pronounced as you zoom further in etc.
