diode Posted January 7, 2014 Share #1 Â Posted January 7, 2014 Advertisement (gone after registration) Hey guys, Â Just got a new M a few days ago and love it. Today after taking a picture I took a look of the image on the back of the screen. I zoomed in two levels to see if I hit the focus and the screen tinted the image red. If I zoom out one level it goes back to normal. I haven't seen this happen on other images I preview/zoom in on. What exactly does that mean when it happens? Â Thanks, -Alan Link to post Share on other sites More sharing options...

jaques Posted January 7, 2014 Share #2 Â Posted January 7, 2014 I don't know what it means- but I have handled two M240 cameras and this happened on both of them. Only on seemingly random images- sometimes a few images in sequence- and only when you zoom in to the image. The images import in LR without issue so I suspect it has something to do with the preview JPEG... but as I say- I don't know. Link to post Share on other sites More sharing options...
diode Posted January 7, 2014 Author Share #3 Â Posted January 7, 2014 Awesome. Yea I haven't had a chance to upload them yet, but was just curious if the camera was telling me I did something wrong. haha Link to post Share on other sites More sharing options...
dugby Posted January 7, 2014 Share #4 Â Posted January 7, 2014 Did you click the "info" button ? just keep clicking the "info" button, you will get a blue highlight, then get back to normal display. Â I don't have my camera/manual with me for the explanation.....they are "clipping indicators" Link to post Share on other sites More sharing options...
jaapv Posted January 7, 2014 Share #5 Â Posted January 7, 2014 If you zoom in on clipped highlights with the clipping warning activated the clipping warning will grow larger too. Link to post Share on other sites More sharing options...
jaques Posted January 8, 2014 Share #6 Â Posted January 8, 2014 no- this isn't clipping highlights. This is a weirdness- the image appears washed out. Diode explained it as red- but I would describe it as magenta hued- and as if only one channel is showing. This happened to me on two M240's - only on random images- and I know what the clipping highlights look like- this is not them. Link to post Share on other sites More sharing options...
BerndReini Posted January 8, 2014 Share #7 Â Posted January 8, 2014 Advertisement (gone after registration) Yup, had the same thing tonight only on one picture. The picture turned a magenta hue when I zoomed in and back to normal when I zoomed out. Completely different from highlight clipping. After I read this thread, I just tried to recreate it and take a picture with my phone to illustrate it, but I cannot recreate the issue. When I play back the same image from tonight, still on my SD card, it acts completely normal. Link to post Share on other sites More sharing options...

Â Agree it's not a clipping issue - had the same, and after a while it was not reproducible, on the same image, still being on the card (may be switch off & on the camera between, can not remember). Must be some SW hiccup... Link to post Share on other sites More sharing options...
viooh Posted January 8, 2014 Share #9 Â Posted January 8, 2014 I've noticed the effect described here with my M, too. It is most certainly a bug, not a feature. Although I can not reliably reproduce it, I have a feeling that it happens preferably with low light images at high ISO settings; I have not seen it in normal (=daylight) shooting conditions. As it doesn't seem to affect IQ, I don't really care. OK, a camera that I've had to pay so much for shouldn't do things like that. Link to post Share on other sites More sharing options...
BerndReini Posted January 8, 2014 Share #10 Â Posted January 8, 2014 Sounds right. The image I experienced it with was shot at high ISO. It wasn't really a problem just a little embarrassing since I was showing the photo to my colleagues at the time. Link to post Share on other sites More sharing options...
Son of Helm Posted January 8, 2014 Share #11  Posted January 8, 2014 Hey guys, Just got a new M a few days ago and love it. Today after taking a picture I took a look of the image on the back of the screen. I zoomed in two levels to see if I hit the focus and the screen tinted the image red. If I zoom out one level it goes back to normal. I haven't seen this happen on other images I preview/zoom in on. What exactly does that mean when it happens?  Thanks, -Alan  Could this still be related to not fully mature batteries?   During the early fall, those of us who were lucky enough to have got our M's, encountered a number of minor glitches: Occasional lock-ups (at normal temperatures), over/under exposure, strong magenta coloring when viewing pictures on the cameras display (not present on the imported DNG files to the PC). These issues were related to the characteristics of fresh Lithium batteries: Li ions have to find their place into a matrix, and this process is eased with recharging/emptying the fresh batteries. Only after a number of such cycles the battery attain the specifications of a mature battery, We observed that after 3-4 such in-camera rechargings the above issues were gone.   With the FWO, work had been addressed to stabilize this situation, but it is unclear to what extent the present FW completely removes the above glitches. From some of the recent statements, the issues seem to go away after a short time (with a recharging, perhaps??). Try this before you send your M back.

BerndReini Posted January 8, 2014 Share #12 Â Posted January 8, 2014 It is not related to recharging. As someone stated above, powering down the camera might take care of it. Either way, this is not a glitch that will be solved by returning the camera. It is more of a "first generation" snag that people just have to live with for now.

jaques Posted January 9, 2014 Share #13 Â Posted January 9, 2014 I doubt it is a battery issue. I can't see how the battery could affect the functioning of the camera like that. Â I actually managed to video the phenomena- so I have proof it exists- if anyone is interested to see it- and knows how I can post the video I will be happy to do so. It does just seem to be a glitch: it does not affect the RAW file at all. As I said my guess is that it has something to do with the in-camera JPEG preview image? though thinking about it I can't see why it would display normally at 100%- and only weird at magnification...?

BerndReini Posted January 9, 2014 Share #14 Â Posted January 9, 2014 I know I'm going to get flag for this and I admit that I don't really know what I'm talking about in this case, but my hunch is that the "Maestro" processor is the source of a lot of M240 problems. I just don't think that the processor is powerful and fast enough for what the CMOSIS sensor is capable of. I believe that with CMOS sensors a lot of calculation actually happens on the sensor level, as opposed to with a CCD sensor such as the one the S system uses. Therefore what's good enough for the S system may just not be right up to the task with the M, thus banding, lockups, slow startup time, handicapped live view etc. Any thoughts?
