I just ordered a panasonic ts10 (should be here today) for my wife's birthday. She used an olypmus 790 SW for several years, and it broke when we were at the water park at Cedar point a few months ago. It was either the force of hitting the water coming down a big slide that broke the seal or she didn't have the compartment closed right. Up to then it was a fantastic performer.
It seems that Olympus has been on the decline as of late with their new products. Image quality is good, but the shooting speed and overall performance is dead slow, like 4 seconds from picture to picture w/o the flash, even on the 8010. I'm sure some of that is the preview mode, but my wife would never want that turned off.
I'm looking forward to the TS10. It's got faster performance than the Olympus and pretty much the same ratings in the water, temp, and drop zones. It gets good marks for images with its auto mode, which is all she needs. I liked the TS3, but it was out of my price range as I wanted to be below $200, and it basically just gives better water depth rating and a wider end of the lens (28 vs 35). Her old camera was 38 on the wide end so she won't notice.
I should be able to post a little more info on it after this weekend when she gets it. I didn't even consider using a waterproof case on a camera. The whole point of this camera is to be a little go anywhere deal that can easily fit in a pocket.
T3i, Sigma 10-20, Sigma 30 1.4, 18-55 kit, 55-250, YN-565, a few books, some software, and a desire to get good.....
