Timkr Posted October 3, 2017 Share #1 Posted October 3, 2017 Advertisement (gone after registration) I was shooting this past weekend on a golf course and noticed a handful of my shots had a horizontal line, all in the same place. Most shots were fine. Here is a link to one with the line. https://timrutledge.smugmug.com/Florida-Sept-2017/i-j2RQtQQ I am hoping it's not the sensor or shutter, just something simple. Thanks for the help. Link to post Share on other sites More sharing options...

LD_50 Posted October 3, 2017 Share #2 Posted October 3, 2017 Looks like a sensor issue to me. Could also be an issue with the memory card so I would try a different one. Link to post Share on other sites More sharing options...
sillbeers15 Posted October 3, 2017 Share #3 Posted October 3, 2017 The horizontal line which appeared in your image looks like 'banding' lines usually associated with high ISO. I had no such encounter with my SL & M10 at high ISO of 6400, but encountered that earlier at ISO3200 on my M240. I sent my camera back to Leica Germany for it to be checked and reset when it was still under warranty period. After which I did not encounter it anymore.

LD_50 Posted October 3, 2017 Share #4 Posted October 3, 2017 That looks like no high ISO “banding” I’ve ever seen. Typically high ISO “banding” is a repeating pattern in the noise, not a single line of what appears to be hot pixels. This either looks like a sensor issue or some sort of card read error. The OP could also try a different RAW developer. Link to post Share on other sites More sharing options...
ropo54 Posted October 3, 2017 Share #5 Posted October 3, 2017 I store my photos in Photos on my Apple iMac. On occasion, one of my stored files will get a similar line. I open the photo, restore it to "original", reprocess, and the line disappears. Give that a try - restoring to original RAW as when imported - and see if that corrects the issue.

Irakly Shanidze Posted October 3, 2017 Share #6 Posted October 3, 2017 It looks more like a bad memory card than anything else. A line of dead pixels would not have artifacts around it. Also, if it happens sporadically, it does seem like a problem somewhere between the buffer and the card. Does it happen to one of a files shot in a very quick succession, or it can by anything? In any case, try a different card first (or at least reformat the one you have and wipe the contacts). If it keeps happening, send the camera in.

Timkr Posted October 3, 2017 Author Share #7 Posted October 3, 2017 Advertisement (gone after registration) All the pics with the line were shot at iso 6400 and at high burst rate. I'll swap the card out first. Thanks for the help. Link to post Share on other sites More sharing options...

Timkr Posted October 4, 2017 Author Share #9 Posted October 4, 2017 I’m using 128gb uhs ii 1000x card. I’ve seen comments that these are problematic. Link to post Share on other sites More sharing options...
lx1713 Posted October 4, 2017 Share #10 Posted October 4, 2017 I think it's probably a sensor overheating combined with the fact you are shooting at 6400. I've had a very similar look with my M8 when I'm shooting a large number of images at high ISO. It had a habit of migrating to lower ISOs the more I stressed the sensor. I doubt it's a card issue as it's repeating over several images in the same place. What's the temperature like and were you shooting rapidly? Link to post Share on other sites More sharing options...

Marac Posted October 6, 2017 Share #15 Posted October 6, 2017 It could very well be the memory card struggling to write at burst speed. I would certainly invest in solid SD card from the Leica store and then try reshooting at ISO6400 in burst mode then if it still produces a line you are in the right place to have it sent off for repair and I would also let them know you are a Professional and will require a loan SL while yours is being repaired.

Irakly Shanidze Posted October 6, 2017 Share #16 Posted October 6, 2017 No That could actually be the problem. Only the lower slot is UHS-II compliant (always read the manual first ). Using this card in the upper slot effectively brings it down to the lower end of UHS-I specifications. While it is perfectly fine for single-shot mode, the card becomes your bottleneck when higher bandwidth is needed. Link to post Share on other sites More sharing options...

I doubt it's a card issue as it's repeating over several images in the same place. What's the temperature like and were you shooting rapidly? SL is very different from M8 in all possible ways. The reason for these sort of artifacts on M8 was its slow (by today's standards) processor, performance of which could be affected by temperature. SL has a much better heat management system than any digital M camera, and is not prone to overheating even in relatively high ambient temperatures. It can shoot 120fps 1080p video until the battery dies (to an external recorder, otherwise there is a 30 min limit), and you won't be able to tell the difference between the first ten seconds of the footage and the last frame in terms of the noise level. Same with 4K, but since SL uses only about 65% of the sensor surface area, this is not a valid comparison. Link to post Share on other sites More sharing options...
