Frustrating - Dead pixels.

[swoop]

So I just received my M240 and after checking it out I noticed there are 3 hot pixels. 2 red, 1 blue, scattered about the sensor. Now I know, 3 out of 24 million isn't bad. But it's still irritating. I shoot RAW 98% of the time and lightroom completely does away with them automatically when using RAW files. So, not the biggest deal. They aren't going to cost me anything in processing time. But when I shoot JPG it's because I'll need those images ASAP and they are still there in JPG images. Also even though I'm shooting RAW I can still see them plain as day on the LCD.

I know, it seems like such a petty thing to complain about, 3 pixels no one will ever see. But it's still frustrating. My M8 had a bunch of dead pixels and it never held me back. My M9, I don't think I ever saw any, truthfully I don't think I ever even bothered looking for them. But on the M240 they're so obvious! Especially now that I know where they are. Another strange thing, they're only there from ISO 200-800, but from 1000 up, they disappear.

it is annoying, if you just got the camera I would send it back to Leica or where you
purchased it, I mean for the price you paid for it they should not be there. Do you
have any pixel mapping on that camera some other cameras do have it.

Send it back to Leica to be remapped thats what I did with my M9 it will just keep annoying you, I don't understand why Leica has not included remapping in the camera, when I got my Canon 1dx one of them had some hot pixels 30 seconds later they were gone, my M9 on the other hand 4 weeks later!

I'd think it a costly problem for Leica to deal with this issue on individual cameras as a service return at no charge. Thus I expect they're motivated to come up with a more attractive solution.

One report about hot pixels on an S model had the customer email Leica an affected file, which Leica then used to craft a special firmware modification, which they emailed to the customer to fix his camera. That was much faster and less costly, but still involved an individual solution.

And the bad part is these hot pixels keep cropping up over time, so a customer-oriented fix would be the way to go.

I just sent my Monochrom in for some dead pixels (and sensor cleaning). Mine would only show up iso 400-800. On some occasions the pixel would even make a vertical band esp if you cranked the exposure a bit in Lightroom.

Thanks for this info. Knowing this, I may pester Leica with a file from my M9-P so they send me a custom FW for my camera to fix a recently acquired hot pixel (probably due to cosmic rays).

It's true they get removed in LR, but sometimes I work directly between the camera JPEG and an iOS device, so I don't want it showing up in the original JPEGs !

They won't. The email service for pixel correction is for S cameras only.
