I bought a pair of these cards for a Canon PowerShot A590IS 8 megapixel 4x optical stabilized zoom digital camera. To my knowledge, if you're running a CHDK hack on an A590, 4GB is the largest card you can reformat to FAT(16) if you want autoload to work when the camera turns on. I reformatted the cards, uploaded the hack and so far the camera is working fine. Four stars for the cards only because they came without sleeves. However for the price with free shipping (from Agfa) this is a great buy.
