Canon Legria HF21


Canon's Legria HF21 camcorder is aimed at the enthusiast videomaker, but how does it compare to its predecessor and rivals?

Canon LEGRIA HF21 review


Thanks to its 64GB flash storage, the HF21 promises to let you shoot 24 hours in Full HD. But will you want it to be your day-tripper?

Great handling and powerful performance, but a little too pricey for our wallet’s liking

Canon Legria HF21 review


With an RRP of £875 inc VAT, the Canon Legria HF21 is significantly cheaper than Canon's high-end efforts yet still hovers above the entry-level mark. Its video performance is acceptable for the asking price, with an impressive array of manual modes...

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.

Canon Legria HF21


This is a small camcorder that has a 64GB of supplied internal memory and 3.3MP stills. 15x optical zoom may not sound huge – by some standards – but try keeping the camcorder still when you have far greater amounts of zoom.

Everything is easy when you have data on an SD card as you just remove the card and place it in card reader, why can’t internal memory allow transfer as easily. This rather negates the point of having internal memory if data transfer is not simple

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.
