Bigger than my previous cameras

Another unit from Canons excellent PowerShot range. Here a small unit with periscopic zoom as this is a waterproof unit and this is essential for those wanting to takes images under water. It also takes excellent dry land images.

I choose the D30 over all the other compact underwater cameras for two reasons: · Image file sizes are smaller, which counts when you take hundreds of photos every day; · Noise reduction has been toned down and does not create a watercolour look in your photos.

I had a Canon D-10, which was great! I'm an advid fly fisherman, and take my camera with me all the time. I dropped my D-10 and cracked the viewing screen. My boys got me this one for my birthday.

Easy To Use; Fast/accurate auto-focus; Good Image Quality; Good Image Stabilization; Large Clear LCD; Small / Compact

Incredible versatility. Took it on our family vacation to Grand Cayman because I am tired of lugging around my Canon 60D with two lenses, and I also wanted a camera for underwater. Land shots are very good, though I did not shoot any macro shots of lizards, fish or flowers.

Overall versatility; including good land shots; decent underwater shots; great depth tolerance; and decent video capabilities

None that I can think of
