I have a slightly later version of that camera, that uses genuine Sony Memory Sticks. Will brain fart if you put in one that is too big ( more than 64M IIRC) and crash and die. Also uses that so lovely 7V2 Infolithium battery, which is a fancy ( and eye wateringly expensive if bought new then and even more so now) package with 2 bog standard lithium ion cells and a small protection board in the fancy case. The one I have is a little dead, as it will charge for 20 minutes, then you place in the camera and you have 10 minutes to take your 4 photos before it does a low battery warning and shuts down. Some day I will repack it, but as my other camera just uses AA cells, and the camcorder works as well for quick and dirty shots it is pretty low. The big advantage it has is that you can do a macro shot in ambient lighting, and have it come out sharp and clear.
