Info on the web is hard to come by on that dinosaur. I found a website that says it uses smart media but no size info, buying a 128 MB card could be a gamble. Your best bet would be to go a camera store (like wolf) and just try em out. A good store should have a some memory sticks around u can try.
it deffinetly uses Smart Media... check that site, Just copy and paste, i didn'the time to Make it into a Link.... It says something about 4MB storage, not sure, But im sure it can handle a larger mem Card
