TX5 in the Water
I've had my TX5 for about three months and have had it in a number of watery environments: snorkeling in Maui, kayaking in Canada, and frequently in the lakes around my home in Wisconsin. A few photos appear below. I am very pleased with this camera in many ways. It seems to be quite at home in the water, and I've grown accustomed to just letting the camera lie in the bottom of my kayak (where I can grab it quickly), not worrying about any water that may get splashed on it. This is one tough camera.
I do rinse the camera after every outing, gently in cool water as the manual suggests. I am careful to move the slider back and forth, wiping each time, until the front surface is dry. I have also been careful to avoid getting sunscreen and mosquito repellant on the camera -- not sure, but I suspect this could be bad news. So far, no issues with paint chipping. I also carry it attached to an Olympus floating strap (from B&H), which assures me that it will bob safely and easy to find should it go overboard.
Image quality is fine for a camera of ths type. I see some flare (I think it's flare) at the wide end in bright scenes, but I think this is expected for a 25mm lens. And sometimes contrast out of camera is a little low, but this is easily fixed in PP.
