wparsonsgisnet Posted August 6, 2007 Share #21 Posted August 6, 2007 Advertisement (gone after registration) James, would you do a test where you fill the buffer and time the recovery (no more red light, blinking) with both cards? Just curious, since as Geoff says they're both "out of spec." Link to post Share on other sites More sharing options...
Advertisement Posted August 6, 2007 Posted August 6, 2007 Hi wparsonsgisnet, Take a look here M8 and 4GB SD Cards. I'm sure you'll find what you were looking for!
geoff Posted August 6, 2007 Share #22 Posted August 6, 2007 As it happens, the Transcent 4gb cards take twice as long to write to as my Ridata 2gb 150x cards. So, the question for the monsters is: given the specs alluded to above, with the sdhc cards be faster than this? For example, it takes 40 seconds with a Ridata 2gb 150x card to recover from a full buffer (with the M8 set to hi-res jpeg + dng, my regular setting), and it takes 80 seconds to recover when using the Transcend card. Yes, in theory, properly certified Class 6 SDHC memory cards should yield better performance and more consistent results compared to the typical state of affairs with SD memory cards. As mentioned, prior to SDHC, speed ratings for Secure Digital cards was left to the manufacturers to self-impose, which resulted in some pretty inaccurate claims and often wide performance differences between similarly rated cards. In addition, one tactic many manufacturers used was to labeled their cards based on loosely defined “read” rather than “write” performance results which served to benefit the manufacturer by confusing the consumer. One intended function of SD Specification Version 2.0, aka SDHC, is to impose a more accurate speed performance labeling system. Hence the switch from “X factor” to “Class” ratings. Currently, there are three SDHC “Speed Class” ratings. Class 2, Class 4, and Class 6, with the later being the fastest. It is important to understand that these ratings specify the minimum “sustained write” speed that one can expect in real world use. Therefore, and of particular note to Class 6 SDHC memory cards, some may perform significantly faster but definitely not slower than their designated rating. • Class 2: 2MB/sec • Class 4: 4MB/sec • Class 6: 6MB/sec In theory, this baseline performance differences between similar Class rated SDHC memory cards from different manufacturers should be negligible leaving issues concerning construction, component selection, warranty and follow-up support as main deciding factors for consumers. Under SD Card Association (SDA) guidelines, compliant SDHC memory cards must have both the SDHC and the Speed Class logo which can only be issued under SDA certification. However, take note of the many cards that do not exhibit the Speed Class logo. Furthermore, leave it up to some popular main name manufacturers to continue to confuse the market place, ambient to their own advantage, by claiming a range of speeds inconsistent with the SDHC Class rating specification.

bsmith Posted August 6, 2007 Share #23 Posted August 6, 2007 I think 138 exposures is more than enough to entrust to a single card. I prefer to spread my eggs across multiple baskets. That's what some photographers said when the cards went from 128mb to 256mb, and then again when cards went from 256mb to 512mb, then 512mb to 1g, then "OMG , 2g !! what if I lose all my photos" 4, 8, 16 bring them on ! Pro's need storage capacity. It's far more risky losing the SD card that you took out , than losing any images on a 4g or 8g card. I've never heard of anyone losing all their images when a card errors out. The M8 should be able to write to ALL size cards, just like $200 point and shoots.

wparsonsgisnet Posted August 6, 2007 Share #24 Posted August 6, 2007 ...Currently, there are three SDHC “Speed Class” ratings. Class 2, Class 4, and Class 6, ... • Class 2: 2MB/sec • Class 4: 4MB/sec • Class 6: 6MB/sec MySpace.com - www.myspace.com/geoffotos Thanks, Geoff, this is more informative than the official site. I wandered around it and got a lot of feel-good stuff but no hard info. I'll do some searches to see what's what. You wonder how they designed the 2, 4, 6 class levels.

jflachmann Posted August 6, 2007 Share #25 Posted August 6, 2007 Jens and Volker, Which cards are you using successfully? I'm using a SanDisk Extreme III 2 GB and a Kingston elite pro 2 GB. Never had problems with am memory card since I own the camera (10 month now). Link to post Share on other sites More sharing options...
photolandscape Posted August 6, 2007 Author Share #26 Posted August 6, 2007 That's what some photographers said when the cards went from 128mb to 256mb, and then again when cards went from 256mb to 512mb, then 512mb to 1g, then "OMG , 2g !! what if I lose all my photos" 4, 8, 16 bring them on !

I've never heard of anyone losing all their images when a card errors out. The M8 should be able to write to ALL size cards, just like $200 point and shoots. That is what I was thinking when I started up this thread. Changing a card is not a big deal of course, but it's a distraction. Cards always seem to fill up when you're in the midst of some serious shooting. With that in mind, I usually try to change cards before they fill up and when there is a break in my shooting, but I'd certainly rather have to do that 1/2 as often. Plus, cards can get lost, dropped, etc., and at least when the card is in the camera working properly, I don't have to worry about it. I know some of my more traditional Leica-phile friends may disagree, but I would love to see the next digital M offer easier battery and card changing. I know changing film on my M4 and M6 involved the same sort of baseplate that one must remove and hold onto while changing batteries or cards on the M8, but I'd rather have the baseplate hinged or have small doors or slots for the battery or cards respectively.

highlander Posted September 1, 2007 Share #27 Posted September 1, 2007 Advertisement (gone after registration) Hi All, Can anyone help I have recently purchased a Sandisk 4GB micro SDHC memory card with a Micromate adapter. I noted that in the literature and on DP Review that the M8 was compatible with SDHC cards. I tried to format the card as it was showing "Card Full" when put into the camera. This was unsuccessful and the only way to stop it was to remove the battery. However when put into the Micromate USB reader the card was formated and showed up as empty, but when put back into the camera still showed as full. Where am I going wrong or is the M8 just not compatible with this type of card? Regards ... Jim. Link to post Share on other sites More sharing options...

highlander Posted September 1, 2007 Share #30 Posted September 1, 2007 Hi Carsten, Go to DP Review on the M8 review under specifications / Storage, it states SD/SDHC and Fat/ Fat32. If the M8 is not yet compatible why have they stated that it is? I have tried to look at the Leica site but all it will say is up to 4GB cards will work. Is there any time scale as to when these cards will or may be compatible? regards ... Jim. Link to post Share on other sites More sharing options...

haroldp Posted September 13, 2007 Share #34 Posted September 13, 2007 I have been using transcend 4gb 150x SD ( not SDHC ) cards in my M8 without incident, although the camera's write speed does not seem to take advantage of the cards speed. I recently ( two weeks ago ) used 4 of these on a 4 week baltic trip. I believe that 4GB capacity is fine, but SDHC is not. An attempt to format a 4GB Sandisk SDHC card in the M8, effectively destroyed the card, and the camera could only be shut down ( after 1 hour ) by removing the battery. Do not try SDHC. I hope this is helpful. I too am awaiting SDHC support, since most cards grearer than 2GB are now in this format. Link to post Share on other sites More sharing options...
cme4brain Posted September 13, 2007 Share #35 Posted September 13, 2007 I know this topic has surfaced from time to time, but I wondered whether the new firmware just released enables the M8 to reliably use 4GB SD cards? Also wondered whether anyone has been using 4GB with much success even prior to the new firmware release this past week? I am heading for Peru and Chile and would love not to have to stop and change cards every 138 exposures or so. Thanks. I use Ridata 150X 4Gb data cards with absolutely no problem.

haroldp Posted October 15, 2007 Share #36 Posted October 15, 2007 I have also been using transcend 4GB SD ( not SDHC ) 150x cards without incident. The M8 destroyed a sandisk 4GB SDHC card. I think other 4GB non SDHC cards should work, but have not tried them. I have noticed that since these postings, the street price of the transcend 4GB SD ( not SDHC ) 150x cards has gone up considerably. That is why I will try other brands. SDHC suppoert would give us many more options. Link to post Share on other sites More sharing options...

egibaud Posted November 13, 2007 Share #38 Posted November 13, 2007 I am not sure high capacity could be supported, I thought hardware was involved too... By the way my 2Gb Ultra 2 give me 187 DNG pictures and my 2 Gb Lexa pro give me 190 DNG pictures.... 3 extra pics :-) why? thought 2 Gb were 2 Gb regardless of card maker.

scho Posted November 13, 2007 Share #39 Posted November 13, 2007 Guy, their watch stopped, right? Nah, just Holidays. Xmas coming and best of all Fasching is creeping in: "Officially it starts am elften elften elf Uhr elf (11th November at 11:11am) and continues in a fairly low-key way for about three months before the Tolle Tage (Crazy Days) which climax on Rosenmontag, the 42nd day before Easter. Carnival season is traditionally seen as a chance for people to go wild and let their hair down before Lent starts on Ash Wednesday. In the Christian church Lent is a serious time before Easter for fasting (eating no food or very little food) and making up for your sins and mistakes." In other words, don't hold your breath - maybe after Easter they will be a bit more industrious. Link to post Share on other sites More sharing options...
willemvelthoven Posted November 13, 2007 Share #40 Posted November 13, 2007 I have 2 Ridata 4GB PRO 150x SDcards. They work fine for about 6 months now. I tested 2 cheaper Ridata cards in the shop and they did not work. just the pro 150x. They were about HK$ 700 each in a tourist photoshop in Nathan Road HK.
