The DSC-TF1 has a better sensor type than most similar spec cameras that have been on the market for around the same time as it. This digital camera has a CCD sensor type, whereas most waterproof cameras that have been around for a comparable time to it 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.
A CCD sensor type is in fact the best sensor type across all cameras of this age and spec.
A MOS sensor type is the worst sensor type across similar types of digital camera.
We compared this digital camera to all the other cameras that have a CCD sensor and we think the Panasonic DMC-FT3, the Nikon 31, and the SeaLife DC1400 Pro which has better reviews is also worth considering.
