Canon EOS Rebel T3i review: Canon EOS Rebel T3i

Canon carries over the control layout and user interface from the T2i, although it has moved the Display button to the top and replaced it with Info. Camera operation is straightforward. On the back there are direct-access controls for Live View/video recording, exposure compensation, white balance, autofocus method (single, AI focus and AI servo), drive mode, Picture Style, AE/AF lock, and focus area (single-point manual or all-points auto). You can also change these settings, plus metering, flash, image quality, and a few others, via the typical Quick Control screen. My one quibble here is that the buttons all feel a bit too flat.

The mode dial includes the usual set of manual, semimanual, automatic, and scene modes . It doesn't lock, which may bother some folks (though not me). As with the 60D, however, I find the placement of the movie mode--at the opposite side of the dial from the advanced modes--insanely frustrating. I've actually missed video opportunities by having to scroll around from shutter-priority mode to video. 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.

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. The scene modes also utilize the ambience selection options, making them a little more flexible.

While Canon offers quite a few options for video shooters, it doesn't have much beyond the basics to inspire or streamline shooting for still photographers. The T3i supplies basic Eye-Fi wireless integration--you can enable or disable the card and the camera provides connection strength information. For bracketing, you're still limited to a three-shot bracket and a range of two stops around the center, though the complete range goes up to seven stops in either direction. And it supports wireless flash. But there's no way to save custom settings, no creative features like time-lapse or multiple-exposure shooting or filters (only a handful of postprocessing effects). Furthermore, with increasing resolutions, the ability to shoot raw plus small or medium JPEG--as opposed to full size--isn't just a pro necessity anymore, especially if you plan to transmit wirelessly. For a complete account of the T3i's features and operation, you can download the PDF manual.

Conclusion
For the money, the T3i is a great choice for dSLR videographers--though the cheaper T2i can still suffice if you don't need the articulated LCD--and is a solid choice for creative still shooters. But while the image quality and general shooting performance are top-notch, if you're upgrading to shoot sports, kids, or pets, the T3i may not be able to keep up.
