I just got the Pentax Optio W10 - the newest of the Optio cameras. It
has 6 mg pixels and no viewfinder. All of the newest digitals are
being made without viewfinders. I had all of the old film Pentax WR
cameras and loved them. I also have a Pentax Optio 550 that is not
waterproof that takes great shots. I put it in a bag and took pictures
on the San Juan River last year, but that is not a really good option
for anything above Class II. The Pentax I just bought came out a
couple of months ago. I'll try to get some whitewater pictures and get
them loaded to my smugmug site. I just have a few surfing right now.
I may try to get them loaded tonight. I'll post here if I do. I chose
the Pentax over the Olympus because the motion stabilizer reviews are
better than the Olympus. I take a lot of shots from the kayak, so
that's a big consideration for me. Also, Pentax seems to try to get a
niche with the whitewater cameras. However, it still doesn't have a
lenses cover. That would have been nice. It also has a "green" mode
to save the battery. Haven't used it enough to see if I really like
that feature, but it sounds good. Good luck, and let us know what you
decide. Renee
