its the same pentax and its waterproof and also video...I have never tried to do underwater but will start trying on each fish after I get a good shot above water and releasing...once its wet it leaves smears on the lense until wiped dry...yeah, that was a nice tip..also is sending me a loomis pushpole and last trip he gave me a 8wt diamondback flyrod...he really enjoys himself out there I guess
