rocheung Posted December 7, 2015 Share #1 Posted December 7, 2015 Advertisement (gone after registration) Hello everybody here. I just join the M246 family and I am very pleased with the camera. I just found a “defect” on my machine and no idea whether other have seems nobody talk about this. When setting the ISO to 640/ 800/1000, with shutter speed 1/12s or 1/15s, no matter in “M” or “A” mode, the image shown on the camera screen becomes “foggy” and lost much contrast. If the image is read on the computer, no such problem was found. I have tried the same setting on another M246 in the dealer, exactly the same problem was found on that unit. Don’t know whether this is batch problem or all M246 are suffering this hidden problem. I am talking to Leica CS and may let you guys know what’s going on. Please share if you found this situation on your M246 too. Thank you. Link to post Share on other sites More sharing options...

rocheung Posted December 7, 2015 Author Share #2 Posted December 7, 2015 Setting out of the mentioned range, e.g 1/8s in ISO 640, or 1/15s in ISO 500, etc, no such problem was found on both computer monitor and camera screen Link to post Share on other sites More sharing options...
250swb Posted December 7, 2015 Share #3 Posted December 7, 2015 Whatever is causing it, faulty camera or user error, the problem is with your camera not mine. Steve Link to post Share on other sites More sharing options...
Akaki Posted December 7, 2015 Share #4 Posted December 7, 2015 the screen of camera is low resolution, and in computer you have a much more possibility to see, also if you pro--print, it it shows you exactly wats going on. i have same problem on my camera screen, but after importing in light room(DNG!) its gone. try with print pro.

jaapv Posted December 7, 2015 Share #5 Posted December 7, 2015 No such problem here. Could it be that you are seeing exposure simulation with an underexposed image? Link to post Share on other sites More sharing options...
Joakim Posted December 7, 2015 Share #6 Posted December 7, 2015 Very interesting, I tested this now and I am experiencing the exact same thing. It is a clear difference between ISO 800 and 400 when shooting at 1/12 s. The screen has certainly much less contrast at ISO 800. I am going to do some more testing.

Joakim Posted December 7, 2015 Share #7 Posted December 7, 2015 Advertisement (gone after registration) I tested again more carefully now and it is clear that I am experience the same thing as the OP and that it is only for some specific values, when testing for ISO the screen is "foggy" at 800 but not at 400 or 1600 when the shutter speed is 1/12 and when testing for shutter speed it is "foggy" for 1/12 but not 1/4 or 1/30 s when ISO is 800. Very strange behavior but not something that really bothers me because I am rarely shooting with this combination of ISO and shutter speed. The exposure value was roughly the same for all test shoots. Link to post Share on other sites More sharing options...
jaapv Posted December 7, 2015 Share #8 Posted December 7, 2015 Tried again. ISO 800/1/12th Normal screen. Firmware 2.0.2.5 Link to post Share on other sites More sharing options...
Joakim Posted December 7, 2015 Share #9 Posted December 7, 2015 Tried again. ISO 800/1/12th Normal screen. Firmware 2.0.2.5 Firmware 1.0.0.4, note that this is the new Monochrom. If my memory serves me correctly you have the first generation MM? Link to post Share on other sites More sharing options...
rocheung Posted December 7, 2015 Author Share #10 Posted December 7, 2015 Tried again. ISO 800/1/12th Normal screen. Firmware 2.0.2.5 That's should be M246, not the Monchrome first generation. Link to post Share on other sites More sharing options...
rocheung Posted December 7, 2015 Author Share #11 Posted December 7, 2015 I think that should have some problem to generate the thumbnail. Last night when I transfer the image through the Toshiba wifi card to my iphone, I found the thumbnail shown on my iphone apps also got the same problem. But after I click for original size image, problem is gone! Link to post Share on other sites More sharing options...
jaapv Posted December 7, 2015 Share #12 Posted December 7, 2015 That's should be M246, not the Monchrome first generation. Actually I tried it on the 240, which should be similar to the 246. However, similar is not identical... Link to post Share on other sites More sharing options...
rocheung Posted December 7, 2015 Author Share #13 Posted December 7, 2015 Hello Jaap. I just check my 240 but no problem. Actually, you may just put on the body cover. It shoots in total darkness and will be more easy to notice the effect. One is nearly 100% black and the problem one is in deep grey something. You may try, more easy to see and judge. Effect is obvious. Link to post Share on other sites More sharing options...
250swb Posted December 8, 2015 Share #14 Posted December 8, 2015 Just for the sake of argument, you are using fairly long exposures for this 'test', so are you sure that by increasing the ISO you aren't simply over exposing the image, and when you import it into another programme on your PC etc. the programme used isn't doing an automatic rendering that compensates for the over exposure making the image look 'normal'?

rocheung Posted December 8, 2015 Author Share #15 Posted December 8, 2015 Steve, none of the above happened. Link to post Share on other sites More sharing options...
Belle123 Posted December 8, 2015 Share #16 Posted December 8, 2015 Actually I tried it on the 240, which should be similar to the 246. However, similar is not identical... Just to clarify, the 240 and the 246 firmware is not compatible, I.e. I can't update my 246 with the latest 240 firmware version. Right? Link to post Share on other sites More sharing options...
rocheung Posted December 8, 2015 Author Share #17 Posted December 8, 2015 Those are not compatible. Link to post Share on other sites More sharing options...
rocheung Posted December 28, 2015 Author Share #18 Posted December 28, 2015 Too bad that Leica still cannot address my problem after checking my sent files, I need to contact my local distributor to demonstrate the problem again. Sorry that you could not update anything this moment. Anyway I do believe that there are some problem for my M246 to generate the thumbnail under the mentioned setting. So tha t when u open the pics in thumbnail size no matter on the desktop computer, smartphones, or the M246 itself, you may see the problem. But when going back to normal size, everything goes back to normal no matter is DNG or jpg Link to post Share on other sites More sharing options...
