Many small point and shoot digital cameras have no viewfinder, just a
LCD monitor which may be hard to read in bright sunlight. The lack of a
viewfinder is perhaps the main reason preventing some photographers from
buying waterproof Pentax Optio cameras. The new shock and waterproof
Olympus Stylus SW 720 also features the LCD monitor but no viewfinder. I
think that this a reasonable compromise in a camera of this size. It
shouldn't stop you from buying these cameras, photographing and having fun.

After paddling with Pentax Optio WP for more than a year, I have
gathered some tips and comments on shooting pictures using these tiny
cameras without a viewfinder.

What is your experience with digital cameras without a viewfinder?
Do you have any other tips, comments or suggestions for photographing
paddlers?
