The DC1400 Pro has a better sensor type than most waterproof cameras that have been available for around the same time as it. This camera has a CCD sensor type, whereas most waterproof cameras that were released more than two years ago have a MOS sensor type. CCD sensors produce high quality, low-noise images but consume a lot more power than CMOS sensors. CCD is the most common image sensor type used in digital cameras.
This digital camera's sensor type (CCD) is in fact the best sensor type amongst all comparable spec digital cameras that were released around the same time as the DC1400 Pro.
A MOS sensor type is the worst sensor type across similar types of digital camera.
Alternative cameras that have a CCD sensor currently available that you might want to look at include the Panasonic Lumix DMC-FT3 which has better reviews.
