Originally posted by Terry C I still quite often use my *ist DS ( had it since new ), and it operates perfectly with a 16GB Sandisk Ultra. No firmware update required. Make sure that it is a new card, not one that has been used in a different camera.
I too have had my *istDS since new.
The update to v1.02 allowed the use of SD cards greater than 1GB
The firmware update to v2 warranted a two-page illustrated set of instructions!
It was v2.01 and above that allowed the use of SDHC cards
What firmware does your camera have?
Just hold the Menu Button down and switch the camera on to get a read-out of the firmware level.
Switch off then back on again and "
Normal service is resumed"
