I tried yesterday the Olympus D-520. I found that one terrific. I was extremely surprised to see that just by plugging the USB cable into the PC that this was recognized as a drive. We used to have that with flash card on laptop but on a PC, wow! This is cool as whenever you travel, you can hook it up to any PC, no installation required (other than the default driver that will be loaded automatically) and you're ready to read directly from the drive.
Most of the digital cameras, when needed to transfer on PC, require you to go thru a software and decide to extract one by one.
It also has a movie recorder that I need. However, it doesn't have sound. The only one that has sound is the Olympus Series C 5050. But, this one is much bigger.
I am looking right now for a Digital Camera that can use USB to build a drive on the PC, able to record with sound, support at least 128 mb card and is as small as the Olympus D-520.
