pico Posted May 9, 2017 Share #1 Posted May 9, 2017 (edited) Advertisement (gone after registration) Pardon if this is posted to the wrong group. I see no generic digital camera group. At this moment I am on MacbookPro rescuing files from a Sandisk 64Gb SD card using SanDisk's reader on a Thunderbolt port. The speed is impressive, almost 80MBs. My ignorance is profound so I am compelled to ask, what is making our Leicas so slow to write data to a fast SD card? A freaking chip, firmware, what?

Jager Posted May 9, 2017 Share #3 Posted May 9, 2017 It's not an easy question to answer, absent access to Leica's hardware designs - the plural is deliberate, because there are several hardware elements at work - and software. But if I am interpreting your comparison correctly, it's rather an apples to oranges situation. Generally, read operations (as in importing files from an SD card) is a faster operation than write operations. Sometimes dramatically so. That's true even if you're looking at comparable computing elements... which in this case, you're not. Your MacBook Pro has a far more sophisticated filesystem, memory structure, caching ability, system bus, operating system, and local storage (if its a reasonably modern version with SSD drive) than any camera on the planet. A better question would be how Leica's read/write operations fare vs. other modern digital cameras. I have no idea, other than to say that empirically, from the M240 on they've seemed perfectly adequate. 1 Quote Link to post Share on other sites More sharing options...
digitalfx Posted May 9, 2017 Share #4 Posted May 9, 2017 My ignorance is profound so I am compelled to ask, what is making our Leicas so slow to write data to a fast SD card? A freaking chip, firmware, what? This has always been Leica's Achilles heel...I don't get it either. The M10 is the first M that is actually fast enough...but I never understood why Leica cheaps out in this department. 1 Quote Link to post Share on other sites More sharing options...
digitalfx Posted May 9, 2017 Share #5 Posted May 9, 2017 I have no idea, other than to say that empirically, from the M240 on they've seemed perfectly adequate. The M240 was still two steps behind...the M10 is the first camera that is on par with competition in this regard. Quote Link to post Share on other sites More sharing options...

Except that my M10 does not seem to be able to write to cards my M240 was perfectly compatible with. Indeed this is Leica's Achilles heel.

UliWer Posted May 9, 2017 Share #7 Posted May 9, 2017 Advertisement (gone after registration) For the M9 there was a beta-test which lead to a new firmware to solve many problems the camera had with SD-Cards. The main problem then was, that the batterie's voltage dropped below a certain base, which caused "irritations" for the files to be written on the card - in cold weather you had most of the problems. The solution was to limit the battery - it stopped working suddenly and you had to reload, not allowing some more shots with very low capacity. As far as I have seen the SD-card issues with the M10 now, this does not seem to be the issue. You may have problems when the battery is fully charged. Though the camera's management of energy might be optimized. Most importand seems to be that the in-camera delete function does not work properly on every occasion. I still have had no problems with cards yet, when I did not delete files in the camera before. Though when I did, cards which worked properly and with good speed before, started to cause problems afterwards. Perhaps it is just the file management after deletion. 1 Quote Link to post Share on other sites More sharing options...

Are you implying that you did not reformat the cards when you switched cameras? 1 Quote Link to post Share on other sites More sharing options...
Stef63 Posted May 11, 2017 Share #9 Posted May 11, 2017 Are you implying that you did not reformat the cards when you switched cameras? How can you reformat a card in the M10 when it gives a "no card available" message? Quote Link to post Share on other sites More sharing options...
pico Posted May 11, 2017 Author Share #10 Posted May 11, 2017 Imitating the amount of time it would have taken to advance film to the next frame? Clever, and I appreciate it, but I do better with an Abrahamsson Rapid Wind on an M2 or M4. . 1 Quote Link to post Share on other sites More sharing options...
jaapv Posted May 12, 2017 Share #11 Posted May 12, 2017 How can you reformat a card in the M10 when it gives a "no card available" message? Ah, you meant does not recognize. Did you run the card through SD Formatter? Quote Link to post Share on other sites More sharing options...
Stef63 Posted May 12, 2017 Share #12 Posted May 12, 2017 (edited) Ah, you meant does not recognize. Did you run the card through SD Formatter? I did indeed tried all or most of the tricks a Leica user got accustomed to owning several generations of digital M's when struggling with what digitalfx called "Leica Achilles Heel". Format in the M240, format in a Leica T, SDformat, standard Mac OS format etc. And it is not one specific card. All of the same model experience te same problem. The positive thing is that between the card models that do seem to work there is less difference in impact on startup speed than in the early (firmware) days of the M240. If my memory is correct in these days the card model made a big impact on startup time. Even the methode used to format a card made a difference. This is in my experience less the case for the M10.
