Wireless flash control is an excellent addition to this camera, which lets the 600D control a number of external flashes. At the time the 600D was launched, Canon also introduced two lower-end speedlights, the 270EX II and 320 EX, though the feature also works with the existing 430 EX and 580 EX II flashes.
To activate it, turn the mode dial into one of the PASM options and press the Q button until the wireless flash control setting is selected. You can set the option to easy wireless shooting or custom shooting. A full video tutorial on how to use this feature will follow this review soon.
Video quality, as with the 550D, is excellent. It's simply the best you can get on any SLR in this particular price bracket. Colour rendition is superb and the video image is smooth. Even the internal microphone seems to produce better audio than on the 550D. The 600D also gets manual audio levels (though still no method to monitor the audio before recording apart from referring to the visual meter).
The digital zoom feature is actually really useful for obtaining just that little bit of extra focal length when filming video. At 3x zoom the image is clear, as it's sampling the true 1080p resolution of the sensor. When zooming in any further, you can see a degradation in quality which is brought about by the interpolation. There's some artefacts present, particularly at the furthest extent of the zoom. See our video below for an example of the digital zoom in action. Note: these sample videos were shot on the 600D with the 10-22mm EF-S lens.

When we first saw the specifications of the 600D we were underwhelmed by the overall similarities to the 550D, which snagged an Editors' Choice award. But, when we put the 600D through its paces, we found these extra features like wireless flash control and an articulating screen to be excellent additions to an already-great formula.
This is a superb example of a consumer-level digital SLR that gets its video implementation right first time. We're sure that all users, regardless of skill level or interest in videography or stills photography, will appreciate it.
