muah Posted March 22, 2019 Share #1 Posted March 22, 2019 Advertisement (gone after registration) dear all. may i ask if anyone has experience the same effect as i did when i shoot at the maximum shuttle speed on a fast lens, i get a black border on the top of my image. is it caused by too fast a lens at large ape rapture and super fast shuttle speed, the camera has not enough time to ‘fill’ all the sensor and as a result a black band appears on top of my capitures image, approximate 1/8 band width. please advise if anyone has the same experience and if my explanation is correct on the black band.

helohe Posted March 22, 2019 Share #2 Posted March 22, 2019 this should not happen. which lens is that? Link to post Share on other sites More sharing options...
lucerne Posted March 22, 2019 Share #3 Posted March 22, 2019 Shouldn’t happen except if the scene is lit by fluorescent lights or something similar like LED.s. It happens because the scene is illuminated by light that is flashing (but you can’t see it), and the shutter is closing before the camera has had time to capture the complete frame. Check your system by shooting outdoors with the same settings, or indoor without lighting. (Set ISO to auto, shutter speed to 4000, and aperture to f2.

jaapv Posted March 22, 2019 Share #4 Posted March 22, 2019 If all other causes are ruled out (see posts above) this would suggest a shutter fault. 1 Link to post Share on other sites More sharing options...

I have returned to my original answer because I think I may have been partially wrong. if there is a fault with the shutter, then you might get the black line. if the lighting is fluorescent, then the flickering frequency of the light might cause the image to have a series of black lines since the exposure is not constant. I suggest you check your shutter first by making exposures in daylight or indoors without any other illumination. If they are ok, then check your lighting. You may have flickering light, or fluorescent bulbs. These are best avoided in photographic situations. Link to post Share on other sites More sharing options...

muah Posted March 23, 2019 Author Share #8 Posted March 23, 2019 (edited) Sorry about non-photo.... here are photos taken of same subject, albeit with different shuttle speed, everything else the same. note black shadowy vignetting above for 1/4000 shuttle vs non-vignetting at 1/750. shoot with Summicron 90 at F2.0 with shuttle 1/4000 Welcome, dear visitor!

dkmoore Posted March 23, 2019 Share #10 Posted March 23, 2019 So many additional variables but still most likely your shutter. Send to Leica. Link to post Share on other sites More sharing options...
muah Posted March 23, 2019 Author Share #11 Posted March 23, 2019 thanks all for inputs. did more checks this morning, it seems the first shot is fine and the subsequent shots at similar shuttle speed will have vignetting on the top. switch off camera and switch on again, no problem with first shot, but again subsequent shot will have vignetting. this leads me to think it should not be a hardware problem but maybe software? tried resetting the camera but to no avail back to leica? =( Link to post Share on other sites More sharing options...
earleygallery Posted March 23, 2019 Share #12 Posted March 23, 2019 Assuming it’s not the flap or strap from a case it’s almost certainly an intermittent shutter fault. Link to post Share on other sites More sharing options...
lucerne Posted March 23, 2019 Share #13 Posted March 23, 2019 (edited) Ok Muah. first, there’s no shuttle on the camera, its a shutter. second, vignetting is usually corners darker caused by something in the path of the lens. Could be inside or outside like a filter or lens shade not fitted correctly.. that’s Not what is appearing on your images. it seems like your camera (shutter hardware or electronics) is faulty. It needs to be returned to Leica. Quickly, because it could get worse. Good luck. Edited March 23, 2019 by lucerne Link to post Share on other sites More sharing options...
muah Posted March 23, 2019 Author Share #14 Posted March 23, 2019 Thank you. indeed it should be shutter. so far only seeing it at 1/2500 speed hopefully it does not get worse till i can send it to Wetzlar. 1 Link to post Share on other sites More sharing options...
250swb Posted March 24, 2019 Share #15 Posted March 24, 2019 Just before sending it off to Wetzlar just check you aren't 'developing' the image with some sort of weird Lightroom pre-set that you've been experimenting with and then forgotten about. It might also be worth resetting the camera to factory default. Link to post Share on other sites More sharing options...
muah Posted March 24, 2019 Author Share #16 Posted March 24, 2019 Thank you. i did reset the camera and also the banding can be seen even before i view the on my computer. Link to post Share on other sites More sharing options...
jdlaing Posted March 24, 2019 Share #17 Posted March 24, 2019 Can the banding be seen when you view on the computer? Link to post Share on other sites More sharing options...
muah Posted March 24, 2019 Author Share #18 Posted March 24, 2019 as well as on computer. did some photos today, still seeing them at high shutter speed. but if i switch off and switch on, i may not get the band. i think it maybe some capacitor not working to keep the shuttle at ‘top’ speed. especially when i shoot in fast mode. i.e. multiple shots, it gets banding for the second and subsequent shots.

Maarten Posted March 26, 2019 Share #19 Posted March 26, 2019 I had the opposite effect with my new M10 from November 2017. I light section at the bottom of the picture, only once every so many exposures. The shutter was replaced in Wetzlar. It took them 3 weeks to send the camera back. Welcome, dear visitor!
