You can find one smaller

BlackSnowman: so far Casio Exilim EX-G1 is the smallest and waterproof I know of... others are too big..

am looking at Sony's waterproof one, but is about double the price of EX-G1...

I don't like Sony's camera...why don't you try Panasonic or Olymic?

BlackSnowman: I'm comparing them all (waterproofs), but the thickness of Pana/Olym just kept drive me away from them...

but too thick is hard to hold it

BlackSnowman: too thin? I like the thinner ones that can fit and easy to carry. 'cause I usually pack with stuffs while travel..

and I take snap shoots quite quick, so bulky ones aren't fit for me... plus I also carry a dslr as well..

oh, that's why ....
