The Mark III also sees Canon introduce a Live View mode to its DSLR range. The mirror has to be locked up to achieve this, metering is set to evaluative and you'll only be able to focus manually (a section of the image can be enlarged to aid with this and we found it worked well).

We found this a good option for crowd scenes - the 3-inch screen gives a wide angle of view, while a grid overlay helps refine framing when you're holding the camera at unusual angles. Shots taken at high ISOs and for longer exposures do start to look a little noisier in the shadows though.

The image quality this camera's capable of is simply stunning. Margarine-smooth images at ISO 100 and 200, low-noise shots at ISO 400 - and eye-openingly good above that. ISO 1600 is of such an acceptable quality that it opens up new photographic opportunities, delivering action-stopping shutter speeds at low light levels.

The files are of such a beautiful quality to begin with that they hold up well to processing too. You'll need to shoot RAW to take advantage of the full potential of this camera, but the results are worth it.
