xjr Posted January 26, 2010 Share #1 Posted January 26, 2010 Advertisement (gone after registration) The camera M9 having taken 8 photos continuously stops and starts the 'buffer' sequence i.e. only after 8 pictures. The card is a sandisk extreme sdhc 30mb/s. Would the number of photos increase before buffering begins if the card were to ,say, 60mb/s ? Link to post Share on other sites More sharing options...
Advertisement Posted January 26, 2010 Posted January 26, 2010 Hi xjr, Take a look here m9 buffers. I'm sure you'll find what you were looking for!
ggits Posted January 26, 2010 Share #2 Posted January 26, 2010 No the buffer stay the same no matter what size of mem card you use. Buffer is pure a internal M9 thing. Without card you can also shot 8 pic ( or 6 - can't remember) Link to post Share on other sites More sharing options...
novice9 Posted January 26, 2010 Share #3 Posted January 26, 2010 The new firm firmware is supposed to improve this situation by a couple of frames, if only Leica would get off its ARSE and complete and release the new firm ware. Are you listening Leica???? Link to post Share on other sites More sharing options...
jaapv Posted January 26, 2010 Share #4 Posted January 26, 2010 What do you want - tested firmware in due course or buggy firmware right now? I prefer Leica to get it as right as possible to firmware buggering up a perfectly functional camera as it is at the moment, by caving in to customer pressure.

ho_co Posted January 27, 2010 Share #5 Posted January 27, 2010 xjr-- I'm sure you've checked the list of recommended cards in the M9 FAQ on the Leica site? Stig is correct. Just to rephrase what he said: We're dealing with two limits: One is the camera's buffer size (8 DNGs), and the other is its write speed. If the card's read speed is higher than the camera's write speed, the camera is the limiting factor and getting a faster card won't help. Maybe a firmware update will speed up the camera's write speed, but the 8-file limit could only be increased by a hardware change. I hope that helps.

35mmSummicron Posted January 27, 2010 Share #6 Posted January 27, 2010 I get 7 DNG's, raw only, no auto review, uncompressed. Takes aprox 27sec to completely clear, and about 3-4sec once you hit the buffer wall before you can take another shot. REALLY hoping a firmware will help write to card faster......

diogenis Posted January 27, 2010 Share #7 Posted January 27, 2010 Advertisement (gone after registration) Guys, the framebuffer is the same if you take compressed/uncompressed RAW pics? Link to post Share on other sites More sharing options...
35mmSummicron Posted January 27, 2010 Share #8 Posted January 27, 2010 Guys, the framebuffer is the same if you take compressed/uncompressed RAW pics? The number of images the buffer holds remains the same--this is hardware. However, what I am implying is that the M9 with its current 1.002 firmware is dealing with SDHC in less than optimal read/write speeds. This is why we are seeing odd/occasional corrupt DNG's, slow format speeds, slow zooming previews on LCD, Sandisk Extreme III cards slower than Ultra II's. If this is the case, the bottleneck then becomes a firmware issue. I realize the M9 shooting uncompressed DNG's is pushing almost 4x the megabtyes than M8, but it feels like it should be able to write faster IE: same number of images before you hit the buffer, but less time to clear, or to write to card, image to image.

35mmSummicron Posted January 28, 2010 Share #9 Posted January 28, 2010 Guys, the framebuffer is the same if you take compressed/uncompressed RAW pics? Hi, sorry just reread your post and didn't realize you were actually asking a question first time around. Compressed DNG's is the same = 7 shots However, it only takes aprox 18sec to completely clear the buffer, although the time from when you first hit the buffer until you can take another shot is still 3-4 sec.

diogenis Posted January 28, 2010 Share #10 Posted January 28, 2010 So, buffer clears faster with compressed raws, but holds the same amount ... crazy Link to post Share on other sites More sharing options...
xjr Posted January 28, 2010 Author Share #11 Posted January 28, 2010 It would appear that some remedial action is required and soon ! if its software fine if not then ...that's it !! Thanks gents Link to post Share on other sites More sharing options...
jaapv Posted January 28, 2010 Share #12 Posted January 28, 2010 Well, that's it then. The buffer is hardware... Link to post Share on other sites More sharing options...
