Besprosvet Posted February 22, 2023 Share #1 Posted February 22, 2023 Advertisement (gone after registration) Hi, I encountered this issue twice in the last days. When I shoot like 5 or 6 photos in a quick succession (like in the span of 15 seconds) the camera keeps writing forever, and the only thing that unstucks it is turning on and off. What happens is that the iso reset to base iso and I lose the whole photos I was shooting. It happened with the M246 today but I remember it happening in the past days, I remember it was with the M240 but I'm not 100% sure. Can it be the card? I use on both cameras Sandisk 90mbs (the ones in the photo) of 32 and 64gb Welcome, dear visitor!

Advertisement Posted February 22, 2023 Posted February 22, 2023 Hi Besprosvet, Take a look here Leica M240 and M246 "freeze" while writing and lose photos. I'm sure you'll find what you were looking for!
wda Posted February 22, 2023 Share #2 Posted February 22, 2023 It would do no harm to use a different card, one with a faster 'write time'. Quote Link to post Share on other sites More sharing options...
PhoToad Posted February 22, 2023 Share #3 Posted February 22, 2023 The reason might be that the "regular" M240 and the M246 have a buffer of only 1 GB, which might be unable to cope with a fast burst rate. The buffer of the M-P (240) with its 2 GB is less problematic in this respect. 1 Quote Link to post Share on other sites More sharing options...

Mhm, I don't know if the M240/246 exceeds the capabilities of this class of card 7 minutes ago, PhoToad said: The reason might be that the "regular" M240 and the M246 have a buffer of only 1 GB, which might be unable to cope with a fast burst rate. The buffer of the M-P (240) with its 2 GB is less problematic in this respect. I mean, to me sounds more like firmware failures (they're both updated to the last one. PS: I don't remember if I was chimping. But even if, it's really expensive gear and Leica should be better than this and delivering reliable products Quote Link to post Share on other sites More sharing options...
pegelli Posted February 22, 2023 Share #5 Posted February 22, 2023 (edited) I just shot a continuous series of 17 photos (until the rate started dropping) on a much slower card on my M246M (SanDisk Ultra 16 GB 30 MB/s) and it took ~20-30 sec for the red blinking light to stop, but after that they were all on the card. So I don't think your card speed of 90 MB/s is the problem. Does the problem happen with both of your cards? If it's just happening with one it might be faulty. Also I regularly format my card in the camera (after the photos are safely on my computer and on an independent back-up location), so you might see if formatting the cards solves your problem.

It happens quite rarely. Yes, I always format the card in camera. If it happened on the m240 as well it's surely not the card to be faulty since I have one for the M240 and one for the M246, I never change between the, (the 64 is on the monochrom) Quote Link to post Share on other sites More sharing options...
pegelli Posted February 22, 2023 Share #7 Posted February 22, 2023 Advertisement (gone after registration) If I were you I'd systematically test each card in each camera (start with their default location) and shoot 10 or 20 continuous series for each of 6-8 shots and see if you can reproduce the problem and see if you can pinpoint a specific camera or specific card that causes the issue.

fotomas Posted February 22, 2023 Share #8 Posted February 22, 2023 How old is the battery? Had this one or two times with one of my oldest battery (about 8 years old). When it becomes empty it seemed to break down completely sometimes. Quote Link to post Share on other sites More sharing options...

Had this one or two times with one of my oldest battery (about 8 years old). When it becomes empty it seemed to break down completely sometimes. They're all old batteries, but it was surely above 50% when this happened, and then kept shooting 100ish photos more with no problems Quote Link to post Share on other sites More sharing options...

I just took the m246 with same card and same battery without even recharging it (it's at 40%) and shot like 4 photos, then 2 then 3 in the span of 15 seconds wile trying to play and delete stuff (to stress the camera). I just reformatted the card in camera since I passed the photos on the HD. I tired this like three times and nothing bad happened. It's some kind of a mistery. I suppose the camera got worked up for some reason, I don't think it's the card being slow, since I read it has a max 40mbs of writing speed. I believe the m240/246 are slower than that, can't find data anywhere about the max BUS speed of these Leica edit: I always format the card in camera after saving the photos, I use this card on the m246 since october, maybe it's that even the latest firmware didn't fix this occasional glitch. If it happens again I'll try to take one photo more to see if that "shakes" the camera to move forward. It was like frozen writing something for a long time. Other few times it just froze, I had to remove the battery Edited February 22, 2023 by Besprosvet 1 Quote Link to post Share on other sites More sharing options...

Idk, given the way I use the m240/246 they seem more like occasional software glitches, I also have a couple of those for my Canon R6, I may give them a try on the Leicas Edited February 25, 2023 by Besprosvet Quote Link to post Share on other sites More sharing options...
jaapv Posted February 25, 2023 Share #13 Posted February 25, 2023 Buy a. couple of new cards (not too large, not too fast) and try the camera with those. Cards can "wear out" and get corrupted sectors etc. Don't swop cards between camera brands, and if you have to, make sure you deep format them. 2 Quote Link to post Share on other sites More sharing options...
