I've had my *ist DS for about two weeks and have been extremly happy with the camera. I however have found one very interesting issue.
When taking long exposures, over 15 seconds in JPEG Best mode, my card reader on my pc won't read the files, SANDISK 1 GB card. I can still hook the camera up via USB and get the data. Can anyone else see if this occurs with there cameras? I'm trying to find out if this is a problem with the camera or firmware in general, or just a problem with mine.

I think this is one for the Tech Support on the Pentax web site -
Mean while you could try aiming a bit higher in the composition then half pressing the release to hold the setting thus forcing a stop down.
I've used Sandisk Ultra II 512M cards, a PQI 1G and a Transcend 1G card (all high speed rated) in the *istDS. I've done about 1500 exposures now, many RAW, and have done several rounds of upload to my computer. No problems at all. These same cards work flawlessly in a Panasonic FZ10 as well.
Either you have had a bit of bad luck, two defective SD cards in a row, or have a *istDS with a stuck or bad memory card controller. Try using the Reset command in the Set Up Menu, see if that helps.
BTW, always format SD cards with the camera once before you start using them.
Auto Picture-selects on of the picture mode such as landscape(mountain), macro(flower), sport/action(running man) mode, etc.
P-sets shutter and aperture. You set everything else.
happy face- sets shutter, aperture and everything else.
Even moving your eye away from the viewfinder can potentially change the amount of light entering the exposure meter, so even if the camera is on a tripod, if AE lock isn't on or manual mode selected, the exposure setting may change.
Have you tried it with lithiums? It may not be a discharge problem so much as a low-battery detect problem. The NiMH are very low voltage even when fully charged compared with a lithium, maybe that's a clue.
Either way it looks like a trip to Mr Pentax to get it orted :-(
FWIW I use lithium AAs routinely, I tried some NiMH that I had and only got about 250 shots per charg and they failed a bit too abruptly - mid file write! - for my taste. I get 800-1200 shots from a set of Energizer AA lithiums, they give me plenty of warning of impending failure, I can stand the cost and I value the peace of mind that they give :-)
