I purchased an SDHC card for my pentax K100 and it does not work - any suggestions?

No, you cannot use SDHC cards with the 450. You can only use MMC and SD cards, 2GB and smaller.

No. The S6 works with SD cards, not with SDHC cards. While SDHC cards will fit into the slot, they are electronically incompatible and will not work with devices not designed to use them. You need to use SD cards, 2GB and smaller.

No. The S40 works with SD cards, not with SDHC cards. You have to use SD cards, 2GB and smaller.

The Optio S6 works with SD cards, not SDHC cards. While SDHC cards will fit into the slot, they are electronically incompatible. You need to use SD cards, 2GB and smaller.

No. The S6 works with SD cards, not SDHC cards. You need to go with cards 2GB and smaller.

Hi,,

Unfortunately, the Pentax K100D is not SDHC compatible, which means that the camera can be equipped with a maximum memory capacity of 2GB.

It is also advisable to choose a fast version of the Secure Digital memory card, such as Ultra II or Extreme III by SanDisk. I would recommend using a memory card of at least 512MB, or even 1GB if you can.

Hope this info helps

Does the camera work with any other card? Was the card formatted in the camera? Some cards from some manufacturers just don't work in some cameras.

My guess is that the K110D is not compatible with SDHC cards.

The E10 works with SD cards. While SDHC cards will fit into the slot, they are electronically incompatible and will not work. You need to use SD cards 2GB and smaller.

The maximum supported size is most likely 2GB SD Card. Cards with 4GB and more are following a new (incompatible) standard called SDHC (SD High Capacity), SDHC cards work only in devices specifically supporting SDHC. The Optio S5N uses the old SD standard where 2GB are the maximum size.
