Help with memory cards !

So I've got the updated firmware onto my Pentax K100 D SLR camera, I want to buy the SanDisk Extreme III SDHC 4GB Card is that definitely compatible? I don't want to make a mistake

I had a K100D which I beleive had the latest firmware, and I know that it was not compatible with the SDHC type cards. I'm not 100% certain of this tho, perhaps someone else can confirm

According to the website, the latest firmware does make it compatible with SDHC cards. Not sure if that is the K100D or the K100D Super though. However, that the K110D is SDHC compatible makes me think the original 100D is as well.

I don't know why you'd go with an extreme III when Ultra II's are a third the price and can be written to at much faster speeds than your camera can write to begin with (at least twice as fast).

Somewhere around here I found a breakdown of the buffer dump speed of a K20D and even it was under 7MBs which can easily be handled by the Ultra II.

That said, I have no idea if your camera is compatible with SDHC cards, but am glad to hear you're lookin at Sandisk.

Yep, with the tiny buffer of the K100D, you won't be doing much burst-mode shooting. A SanDisk Ultra II is plenty, an Extreme III is a waste of money.

Adorama has 1 gb Ultras for about $7.50, but Transcend Class 6's are cheaper and bigger, too.

If memory serves: Class 3 is 6MBs, Class 4 is 12MBs and the Ultra II is 15 MBs read and 13MBs write(maybe 15). Most cards, especialy Sandisk are faster than thier "Class" requirements, so most Class 3 cards would suffice for a K20(Pentax's fastest writing camera). The K200/K10 would be slower than a K20.

The Extreme III writes at 30MBs(maybe 32).

So the only real benefit in a faster card is the speed it can transfer to your computer, but that's not worth the extra $ IMO.

Even my HD video camera only writes at 12MBs.

Without commenting on the need for various speeds, I can say that undoubtedly the K100D with current firmware supports SDHC cards, so you can use the high capacity cards.

Even the *ist DL I just bought uses the latest SDHC cards with the new firmware. No need for speed, though.
