mdg1371 Posted November 14, 2015 Share #1 Posted November 14, 2015 Advertisement (gone after registration) I ran into an interesting phenomenon today-- I had an SD card inserted in my M240 that I have used in both my M240 and M246. Viewing the images in playback, I could view the images from both cameras on the LCD, but viewing the M246 images in the zoom/ magnify mode, I can zoom in 1 step-- if I attempt to zoom in further, the image is completely black. This happens only with the M246 images, and continues to occur after resetting factory defaults, pulling the battery, and reformatting the card. This does not occur with M240 images viewed on the M246. I am running the most recent firmware also. Has anyone else run into this? Link to post Share on other sites More sharing options...

jaapv Posted November 14, 2015 Share #3 Posted November 14, 2015 But it is never wise to use one card in different types of camera - even if they are as closely related as these two are - without formatting it before use. The DNGs are basically different, in fact, it is surprising that you can view them at all. Link to post Share on other sites More sharing options...
mdg1371 Posted November 14, 2015 Author Share #4 Posted November 14, 2015 Should have added, I was shooting DNG+jpeg Link to post Share on other sites More sharing options...
jaapv Posted November 14, 2015 Share #5 Posted November 14, 2015 Yes, but the camera needs to collect the data from the DNG to create the (zoomed) image. Link to post Share on other sites More sharing options...
mdg1371 Posted November 14, 2015 Author Share #6 Posted November 14, 2015 Is it possible that viewing the full image, and the first stage of magnification could be drawn from the jpeg? It seems that both bodies have always hesitated a bit when initially magnifying past the first stage of zoom-- pretty sure my M9 did that as well, a minor annoyance when you want to check a focus point quickly-- Link to post Share on other sites More sharing options...
jaapv Posted November 14, 2015 Share #7 Posted November 14, 2015 Advertisement (gone after registration) As far as I am aware the camera initially displays the embedded JPG, but after a very short interval displays its own calculated JPG. You can see this happening on the M8 which is a lot slower. The delay in zooming is indeed the recalculating. Others may chime in with more in-depth knowledge.

mdg1371 Posted November 14, 2015 Author Share #8 Posted November 14, 2015 Figured it out. Removed the card from the M240, put it in the M246, this time set to jpeg only. Shot a frame, and then viewed it in the M240. Magnify worked fine, without blackout, or any hesitation in zooming. Also tried jeg only in the M240, zoomed without the hesitation. So, it appears, the full view and first stage zoom are from the jpeg, subsequent magnification is from the DNG. Link to post Share on other sites More sharing options...
microview Posted November 14, 2015 Share #9 Posted November 14, 2015 When, briefly, I had an X113 I muddled up cards with my M240's. It listed the DNG number but you could not see the pic. Link to post Share on other sites More sharing options...
mjh Posted November 15, 2015 Share #10 Posted November 15, 2015 Yeah, the M (Typ 240) cannot develop raw files created by the M Monochrom (Typ 246) – wich it would have to in order to create zoomed views. While the M (Typ 240) is able to develop its own raw data, it is far from being a universal raw converter for all kinds of Leica cameras. Link to post Share on other sites More sharing options...
250swb Posted November 15, 2015 Share #11 Posted November 15, 2015 Removed the card from the M240, put it in the M246, this time set to jpeg only. It's still a bad idea even if you figured it out. Steve Link to post Share on other sites More sharing options...
Joakim Posted November 15, 2015 Share #12 Posted November 15, 2015 I assume it is only a bad idea if you're switching cards between two Leica cameras because otherwise the images would end up in different folders so there would be no mix-up because a Leica brand camera would only look in a Leica named folder for photos.

250swb Posted November 15, 2015 Share #13 Posted November 15, 2015 Every time you put a card into any other camera you should format it in that 'new' camera. Equally you should format the card after uploading all the images on it rather than simply delete them from the card. It is good housekeeping. Switching cards willy-nilly between cameras without formatting them can (on the basis that accidents happen) one day lead to a wrongly formatted card being used in the wrong camera allowing for the possibility of glitches and faults creeping in. Beware of the person who says 'it has never happened to me'. Steve Link to post Share on other sites More sharing options...

Not. Accidentally using an Olympus-used card in my DMR led to the DMR needing a firmware reinstall. (it worked fine - or so it appeared, but all files of a higher number than 27 were corrupt. It is more than good housekeeping. It is ensuring that your camera actually works all the time, not only when you are lucky. Link to post Share on other sites More sharing options...
Joakim Posted November 16, 2015 Share #15 Posted November 16, 2015 Fair enough, if I assume camera software worked properly it wouldn't be an issue but that is of course a dangerous assumption and furthermore if I involve more cameras, i.e manufactures, I also increase the possibility of being bit by a software bug. I have only done this once or twice and even among my Leica cameras I tend to divide what cards I use with my M9 and my M 246. I do not see the need to format the cards every time though since I am now using a workflow where I use the SD card as a back-up when I only have access to my laptop and not my main archive.

jaapv Posted November 16, 2015 Share #16 Posted November 16, 2015 It has little to do with properly working software. There are many different types of proprietary files and even the universal DNG format has various variants. It is hardly surprising that camera makers tend to optimize software for the type of file their own camera produces. That it may conflict with another type of file from time to time is unavoidable. It is up to the user to use the gear within its parameters. Formatting cards between cameras is standard procedure. Link to post Share on other sites More sharing options...
Joakim Posted November 17, 2015 Share #17 Posted November 17, 2015 Sorry but I don't follow, each camera brand creates their own top folder (under the DCIM folder) and the files are stored in that folder. How can files stored in one folder affect files stored in another? Are you saying that camera makers doesn't care about the file system for SD cards and make up their own rules on how files should be stored on a card?

mjh Posted November 17, 2015 Share #19 Posted November 17, 2015 Sorry but I don't follow, each camera brand creates their own top folder (under the DCIM folder) and the files are stored in that folder. All vendors except Canon; Canon cameras happily write their files to any subfolder that happens to exist. So if you wonder where your Canon shots went – they are probably to be found in a folder created by a Leica etc.. How can files stored in one folder affect files stored in another? They don’t. I rarely format my cards and I use the same cards in different cameras from different manufacturers. The file system used by all camera vendors is designed to support that kind of use.
