Toto has mentioned this but it's worth reinforcing that if you have a Poseidon compatible memory card reader you can use any digital camera that has a removeable memory card. Card readers are available that read all common types of card in one unit.

I've just bought a Canon A80 digicam which doesn't work directly but I can download its images very quickly by putting the compact flash card in my card reader.

BTW I don't have a Pegasos but I'm sure Poseidon works the same on all platforms it supports.
