Pentax *ist DS USB Cable

Same thing happened to me! :-( I think we are boned.

The camera uses SD memory cards. SD cards max out at 2GB. SDHC cards run from 4GB up, but they cannot be used in SD devices. SD cards can be used in SDHC devices.

The short answer is 2GB.

You should be able to use 2GB SD cards. Cards larger than 2GB are actually SDHC cards and will not work with this camera.

Try using another lens, if this solves the problem you have a lens problem. If not the camera is the problem.

If you want to use the aperture ring on the lens you must enable this in the Custom settings menu. jamknight, sounds like your camera may need a professional cleaning.

First make sure the camera is not set to No Flash on the shooting mode dial.Also, in P, Tv, Av or M modes the flash reverts to manual and must be raised manually by pressing the button next to the viewfinder.

Go to the following page and select category "cameras", sub category "Digital SLR" & you will find all the *istDS manuals for download: http://www.pentaximaging.com/customer_care/manuals_literature Please update the question & let us know if the information given was useful to you - Good Luck!

Check the battery contacts in the camera. Perhaps they are dirty and need a clean. Make sure you're not using Alkaline battereis and if you use rechargeables they are fully recharged and not getting too old to hold a full charge. Apart from that, without further information I can't help any more. BMW

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.

Looks like its true... Another major disadvantage. Removing TTL means removing one more hardware piece - TTL sensor. Pentax removed almost every nice feature, which needs some aditional or more expensive hardware: no TTL flash, less AF points, pentamirror... Seems like I bought Ds right in time.
