Reply from Spamcan : What is the maximum side SD card .....

WOW, I was confused before I asked the question.
I am even more confused now

Many many thanks to all who answered my question. I think I shall stick with just 2gb.

Be careful before you get a larger card. Older versions like my ist Ds will only take 2Gb. So check compatability first.

No, the Ds will take any SD card, including SDHC cards if you have the latest firmware.

I must appologise Spamcan your simple question ended up getting run through our forum super computer Thanks Matt. But i hold George responsible

Your apology indicates that you yourself feel responsible, Clarky, and that is how it should be!

Okay, I'll try to simply things for you, Spamcan. There are two primary considerations when buying a new SD card. The first is the memory card capacity of the camera. The K100D supports both SD and SDHC memory cards. The SD memory card standard supports a maximum of 2 GB while the SDHC memory card standard supports a maximum of 32 GB. The non-standard SD cards exceeding 2 GB are not recommended due to potential compatibility problems. So, theoretically, your K100D supports memory cards up to a maximum of 32 GB.

Your second consideration is compatibility with the SD card reader on your computer. Older card readers will not support the SDHC standard while newer card readers will often support both SD and SDHC memory cards. Therefore, you need to establish which of these standards your specific card reader will support and purchase a card compatible with that.

After those two, pretty much everything else is a matter of your budget and desires. Larger capacity cards obviously cost more than lower capacity cards. Further, current SD and SDHC cards are rated by their minimum sustainable write speeds of 2 MB/s (Class 2), 4 MB/s (Class 4), and 6 MB/s (Class 6), and typical maximum write speeds of 0.9 MB/s (6x), 6.0 MB/s (40x), 10.0 MB/s (66x), and 20.0 MB/s (133x), with faster cards usually costing more than slower cards. Which you buy is entirely your choice.

Many, many thanks to all who have taken the trouble to reply to the original post.
Having checked the firmware version of my K100D which is running on ver:1.00. I believe I need to download the firmware upgrade which is now v:1.2. Once I have the courage to do this it should make my K100D fully compatable with SDHC cards.
I am learning more and more every day thanks to the Pentax Users Forum.

A very merry christmas and a happy new year to everyone ....... Spamcan

I don't know where you guys find the upgrades. In my sources, the latest software version is 1.0.2, not 1.2. There is a significant difference...

It would be useful if you mention which body your post refers to. The latest firmware for all Pentax digital camera bodies is available here. The *istDS, referred to above, is up to version 2.02.

Agreed, mannesty, the model should always be mentioned. However, I found it rather obvious that we were discussing the K100D body.

I have checked the source again, and 1.0.2 is still the latest upgrade for the K100D.

I saw only the DS references. I missed the reference to K100D, so it wasn't obvious to me, although it should have been.
