A week or so back I asked about the compatibility of the istDS (and, the DS2 and DL as well) with 4GB SD cards. A few responses suggested the camera "should" be able to handle them. I decided to look further for an answer, and contacted Pentax directly. This afternoon I received a response:
================================ Currently, the *ist DS camera with firmware version 2.0 supports 2 GB SD cards (SD Association version 1.1). When newer SD cards with the designation "SDHC" (SD Association version 2.0) of capacities of 4GB become available Pentax will support this new SD card standard with a firmware update for our *ist DS camera. There are 4 GB SD cards not carrying the "SDHC" designation available now, but these were released prior to the definition of the SD Association version 2.0 standard (SDHC) and could well be incompatible with our cameras. In summary, Pentax plans to support the new SDHC standard (and higher capacity SD cards) as it comes on line in the very near future but our *ist DS, *ist DS2 and *ist DL camera are currently compatible with SD cards 2 GB and less. ================================ The way I read it, some 4GB cards may work with these cameras now, but Pentax does not officially support them. IOW, you're on your own if you decide to use such cards before the next firmware upgrade. Shel
