Canon Legria HF21 Full HD camcorder


A midrange flash memory-based camcorder with good image quality and features

Impressive high-def video quality, solid array of modes and features, 64GB inbuilt memory

Video performance struggles in low light, no 'Easy' button for novices

The Canon Legria HF21 is a solid workhorse of a camcorder that ticks most of the right boxes. On the other hand, it doesn't do much to distinguish itself from similarly priced rivals.
