Overall the video shooting isn't as seamlessly integrated as it is on the 7D - you still have to select a separate mode to engage video shooting for one thing.

Reviews Word on the street for the Canon Rebel T3i

It's only available in Full HD mode, and when set to 3x it crops into the central portion of the sensor, effectively producing a full-resolution output in which one sensor pixel corresponds to one output pixel.

The Canon EOS 600D's maximum shutter speed is 30 seconds and there's a Bulb mode for even longer exposures, which is excellent news if you're seriously interested in night photography.

At 135mm the 18-145mm kit lens has produced an image displaying good levels of sharpness and detail.

Another significant addition is the Wireless Flash option, which allows the camera's pop-up flash to be used as the master for other Speedlite flashguns.

Ironically, this design is more suited to pros who plan to use the camera as a cheap video dSLR and never take it off the video setting than to the consumers at whom it's ostensibly targeted.

What People Are Saying Give it to me straight


Used at 18mm the Canon 18-135mm IS kit lens is able to fit plenty in the frame, although it does produces some notable barrel distortion.
by TrustedReviews (May, 2014)
The new lens claims an extra stop of image stabilization, but I didn't find it more effective (of course, it's always possible that I'm a year shakier).

By selecting the A-Dep shooting mode we’ve asked the 600D to maximise the depth of field and yet it’s selected an aperture of just f/3..
by TrustedReviews (May, 2014)


As usual, the video looks very good.
by c|net (Mar, 2011)
Once the mode dial has been turned to the relevant position, video recording may be started by pressing the dedicated button on the rear.
by TechRadar (Dec, 2011)
The small, light and friendly EOS 600D fits that bill very well, yet it also offers enough features for both the beginner to grow into and to tempt the more experienced user, most notably 18 megapixels, ISO range of 100-12,800, 63-zone metering sensor, full HD movie mode and built-in wireless flash control.

Using the ‘Landscape’ Picture Style has increased the vibrancy of both the cherry blossom and the blue sky behind it, with fairly pleasing results.
by TrustedReviews (May, 2014)
Canon's version of an easy mode, Creative Auto, operates via what it calls "ambience selection"-Standard, Vivid, Soft, Warm, Intense, Cool, Brighter, Darker, and Monochrome-for which you can set it to one of three levels.
by c|net (Mar, 2011)
Canon's triple-digit EOS line has traditionally catered for those dipping their toes into DSLR photography, but as successive models have acquired more functionality, they've ventured further into enthusiast territory.
by TechRadar (Dec, 2011)


From the front it simply looks like the newer model has bulked up a little, while on the top-plate the only changes are to the design and functionality of the mode dial, and the addition of the display button, whose former space on the rear is now taken by an Info button.
by TechRadar (Dec, 2011)
The LCD screen moves freely about its hinge, although accessing the Menu and Info buttons above it can be awkward when the screen is pulled away from the camera's body, because in most positions it's directly in the way.
by TechRadar (Dec, 2011)
And of course, you can choose to fold the screen back in towards the camera body for extra protection when it’s not in use.
by TrustedReviews (May, 2014)


In live view 'Live Mode' the whole package is considerably less impressive - the accuracy is fine but focusing will regularly take 3-4 seconds.
by DPReview (Mar, 2011)
The four-way controller provides direct access to white balance, focus and drive modes, and picture style during normal shooting, but there's no hard button for metering mode.
by DPReview (Mar, 2011)
We found this mode change somewhat disconcerting, and more than once ended up inadvertently changing the AF point position when we really wanted to set the white balance or drive mode.
