Just came back from scenic Tateyama in the Japan Alps to catch the Fall colors. You can see some pics here,
I have the complete TG1 kit including both TCON and FCON lenses, as well as the 40m underwater housing.
Regarding the camera's operation, I am quite suprised how rare the camera's various exposure programs make use of the F2.0 aperture, considering its touted as THE primary feature. Looking back thru all 760+ pics I have taken so far, from 20m underwater to blazing sunlight I found only 3 taken @ F2.0!
While the exposure programs generally try to maintain a low ISO, it seems that they prefer to stop down the lens in normal light rather than increase shutter speed for correct exposure. The fastest shutter speed I've gotten is 1/800sec, almost 2 stops slower than the 1/2000sec spec. Strange in that these small lenses are best used wide open and apertures smaller than F4 usually cause diffraction issues with these small pixels. It really is too bad the camera allows for no real control of its exposure values.
FWIW, a few features I've come to like while hiking are the camera's HDR, Panorama, and its uncannily smart use of fill flash. The GPS, barometer, altimeter and compass are also very helpful. I have still not tried any of the Magic filters
The camera can definitely take nice pics, especially for web or monitor display, both indoors with its Low Light mode and out. That said, if you never see yourself using this camera in or underwater I would consider another camera. But being waterproof does open up lots of creative perspective opportunities.
