I have a Transcend 4GB SDHC and a sandisk 16GB ultra II.They both work fine with my K200D. The Transcend can store up to 840 pics and the Sandisk is 999x3.5
hehe
I only have some problem with my Apacer 1gb (60X) and *istDS, when I took almost full off the card and try to edit some pictures, the camera sent out error message and I could not use the card in the camera. I had to retrieved the pictures with my laptop and formated the card.
The next few weeks, after a whole day trip, I put my card (no space left) into my laptop and copy the pictures to my HDD, the work seemed fine but after the copy, the cardreader kept reading the card, I simply took it out and the card passed away :ugh:
( I still keep the remain of the apacer and use as the dummy to fill the SD slots
)
My asumption is there is some kinds of camera / card compatible like RAM/ mobos or CPU/chipset in the old days, So just try and find the compatible ones.
Good luck
