"Great camera!"5.0 starson by maytrix0
Pros: Affordable underwater housing
Improved zoom level over prior models
Cons: None that I have found
Summary: I upgraded to the M30 from an HF100 for a few reasons. One was primarily due to an issue with my zoom on the HF100 and the choice that made it easy was that I wanted an underwater housing and upgrading and getting Canon's housing was really cheaper then getting housing for the HF100.
The camera works great both in and out of the water. Quality is excellent and it's easy to transfer video and photos to a computer.
I'd highly recommend this or any others in Canon's line as they all provide great quality.
