    Hmm, I haven't had any problems. We have two 16GB 133x Kingston cards and I personally have 2 266x Kingston cards and have not had a problem with either. Generally I reach for my Sandisk Extreme III cards first, but that is mostly because it seems like a good size (about 200 images/card).

    I have a few trips coming up and will probably get the Transcend 8g or 16g 400x cards.

    The Lexar 300x 32GB doesn't work properly in the A850. It works for about 5-10min, after which the camera hangs and produces a "card error". Having only used SD cards the last 5 years I had totally forgot about all this CF card compatibility crap...

    Re: A850 observations

    Bill, not everyone has problems with them, and some sizes seem to be reported as problematic more often than others. There are enough reports that I avoid them, and encourage others to do some research, check return policies, etc. if they chose to buy them. One of many discussions on the subject here(Google knows of many more). http://www.dyxum.com/dforum/a900-con...opic51656.html

    YMMV

    Re: A850 observations

    I got tired of putzing around with this silly card stuff, so dashed over to Calumet SF on Bryant St. for a Calumet ProSpec 420x 32GB card - and it works flawlessly. I just had a 20min smoke test the Lexar would never have made it through - shoot continuous (uncompressed raw, no JPEG), review, delete a bunch, shoot, review, repeat. Reformat after a little bit, then start over. Not a hiccup.

    Performance wise I get 16 shots at 3fps on the A850, then it delays about 0.5 sec on the 17th. At the flush-limited rate it continues at about 1fps. It takes 13 seconds until it's done flushing after the last flush-limited shot. This is just watching a wall clock, so nothing particularly precise.

    At $150 it's not a terribly cheap card, but so far so good!

    Only card I ever had problems with in the A900 was a Transcend 133X 16GB, I changed to multiple Kingston 8GB 266X and no problems at all.

    Re: A850 observations

    On the suggestion of a very helpful forum member (thanks, Giorgio!) I repartitioned the Lexar card using Disk Utility and reformatted (in camera). It now works flawlessly! I suppose it may come with a bad partition table, or some other funk... So anyone with a similar problem, try the same before returning, selling, or throwing away a card!
