briweed Posted December 17, 2013 Share #1 Posted December 17, 2013 Advertisement (gone after registration) All, I just picked up my brand new M 240 tonight and was playing with the live view. I notice a thin vertical light blue line sometimes on my live view screen (does not show up in photos). Seems to come and go. Has anyone ever seen this? I have not tried in the light of day. Just looking to see if it is normal or if something is wrong with my unit. thanks in advance, B Link to post Share on other sites More sharing options...

BrianNakata Posted December 17, 2013 Share #2 Posted December 17, 2013 I received my M about a month ago and noticed a similar issue about two weeks ago. Mine appears as a vertical line in the same location on either the LCD or EVF and is mostly green. It is always visible when viewing a dark scene. Bright scenes wash out the line and it isn't visible then. It's interesting that the line does not appear in stills or movies, but is plainly visible in either LV display as I indicated above. This must be an issue in the display path only, not the sensor path. I'm going to wait until after the holidays to send in the camera for diagnosis and repair.

jip Posted December 17, 2013 Share #3 Posted December 17, 2013 This is probably something because of ultra high ISO: While in Live view, the view you are seeing is 25fps, meaning that if the lightning situations would need ½ second at ISO 3200 that it would need 4 stops higher ISO to show 1/25th shutter speed... Meaning ISO 23600 something the camera does not support, what it does in live view is push the live view in dark situations... You'll notice you won't see it when having plenty of light. If you DO notice it when it's daylight, then yes there is maybe something wrong. Link to post Share on other sites More sharing options...
BrianNakata Posted December 17, 2013 Share #4 Posted December 17, 2013 I will do some more tests tonight, but I can point the camera at a bright TV scene with only the affected area showing the dark bezel of the TV and can easily see the line. I'll try to take a photo of the LCD when in this situation to demonstrate. Obviously, the camera won't be pushing the ISO due to the majority of the frame being illuminated by the bright TV picture so I'm not buying this explanation.

My dealer had not seen this behavior. I showed them and their response was to get me a replacement camera (while I use the current one I have), since the thing is less than 8 hours old. One question I have is does the line go away when you click down half way on the shutter release? (lock exposure) B Link to post Share on other sites More sharing options...

It does not happen all the time and appears to go away when I lock the exposure. B Link to post Share on other sites More sharing options...
BrianNakata Posted December 18, 2013 Share #7 Posted December 18, 2013 Advertisement (gone after registration) When I got home last evening, I picked up my M, turned it on, enabled LV, and didn't see the line. This is the first time it's been absent since I first started noticing the issue. Then, just before retiring for the evening, I tried it again and the line was back. I framed a relatively bright area in my kitchen where at ISO 200, the camera was metering 1/60 sec @ f/1.4. When I reframe slightly (making sure the shutter speed was well above, i.e., faster than 1/30 sec) to put the area where the line shows up over a darker area, the line was still visible.

Brian Your experience sounds spot on to when I showed my dealer. He played with the camera for 5-10 minutes and saw no line. I then tried something similar to what you did above and the line appeared. I was running the same firmware (2.0.0.11), and also tried upgrading to the latest firmware (2.0.0.12) and resetting the camera to factory defaults. Neither fixed the problem.

I tried it in a variation of light, shutter speeds, apertures, ISOs. Link to post Share on other sites More sharing options...
