The The new EOS Rebel T4i features incredible image quality with an 18-megapixel CMOS (APS-C) sensor, DIGIC 5 Image Processor that is the first Canon DSLR that claims to offer continuous autofocus in movie mode and live view, which Canon calls “Hybrid AF”. This feature, intended mainly for video recording, is implemented through a new sensor technology in which certain pixels are dedicated to phase-detection AF (traditionally used in DSLRs) and others to contrast-detection AF (used in camcorders). When the subject is in the center of the frame, phase detection is used to identify the subject’s current location, with contrast detection then used to fine-tune the focus. Hybrid AF will be available with all lenses, but other improvements to video autofocus, specifically in smoothness and quietness, will depend on the use of Canon’s new STM lenses, two of which were announced alongside the The new EOS Rebel T4i features incredible image quality with an 18-megapixel CMOS (APS-C) sensor, DIGIC 5 Image Processor that . DPReview noted that the Hybrid AF system was similar to the focusing system of the Nikon 1 mirrorless cameras.

The The new EOS Rebel T4i features incredible image quality with an 18-megapixel CMOS (APS-C) sensor, DIGIC 5 Image Processor that is also the first DSLR from any manufacturer equipped with a touchscreen, although it is not the first interchangeable-lens camera with this feature. Almost all shooting parameters and camera functions can be controlled either via the touchscreen, or by buttons and the control dial.

The AF system used for stills shooting through the optical viewfinder is inherited from the EOS 60D. All 9 points are cross-type, as opposed to only the central point in the 600D.[5] The central point is also dual cross-type (i.e., also sensitive to diagonal lines) at f/2.8.
A more complete feature list follows:
18.0 effective megapixel APS-C CMOS sensor
DIGIC 5 image processor with 14-bit processing
95% viewfinder frame coverage with 0.85× magnification
1080p HD video recording at 24p, 25p (25 Hz) and 30p (29.97 Hz)
720p HD video recording at 50p (50 Hz) and 60p (59.94 Hz)
480p ED video recording at 50p (50 Hz) and 60p (59.94 Hz)
5.0 frames per second continuous shooting
ISO sensitivity 100–12800 (expandable to 25600)
3.0-inch Clear View II LCD touchscreen with 640 × 480 (1.04 MP) resolution
9-point auto-focus system, all cross-type
63-zone color sensitive metering system
Built-in Speedlite transmitter, supporting Canon’s latest radio-controlled flashes

The new EOS Rebel T4i features incredible image quality with an 18-megapixel CMOS (APS-C) sensor, DIGIC 5 Image Processor that helps capture all the action with high-speed continuous shooting of up to five frames per second (fps) and an extended ISO range of 100-12800 (expandable to 25600 in H mode) that gives photographers the opportunities to take the EOS Rebel T4i into more shooting situations than ever before.

The camera includes a revolutionary new autofocus (AF) system to help achieve fast, sharp focus and smooth HD video. The new AF system includes a nine-point all cross-type sensor array, and new Hybrid CMOS AF which achieves fast focus when shooting stills or video in Live View mode. Much to the pleasure of aspiring student filmmakers and parents everywhere, the Rebel T4i features Canon’s new Movie Servo AF providing a quiet, continuous AF during HD video recording when using one of Canon’s newly introduced Stepping Motor (STM) lenses. The silent continuous autofocus when shooting HD video helps ensure the camera only captures the sounds of the scene being recorded. When combined with the camera’s new Vari-angle Touch Screen 3.0-inch Clear View LCD monitor II and intuitive “fingertip” controls, touch-menu and advanced still and video capabilities, the EOS Rebel T4i stands as Canon’s most “consumer-friendly” DSLR to date.

“Our Rebel line of cameras bridges the gap between the casual photographer and someone looking to advance their photography and capture moments in new and creative ways. The EOS Rebel T4i boasts full HD video with AF and touch-screen navigation, inspiring even more photographers and videographers to explore the creative options made possible with DSLR cameras and lenses,” said Yuichi Ishizuka, executive vice president and general manager, Imaging Technologies & Communications Group, Canon U.S.A.

New AF Capabilities
One of the most significant upgrades to the EOS Rebel T4i is a dramatically upgraded AF system including a nine-point all cross-type AF array, with a high-precision dual-cross f/2.8 point at center. The EOS Rebel T4i is the first Canon camera to feature the new Hybrid CMOS AF system which increases AF speed by reducing the camera’s need to “hunt” for focus. The result is fast continuous AF when shooting photos and movies in Live View. Because the camera’s cross-type AF points have two-dimensional contrast detection, the EOS Rebel T4i provides highly accurate focus regardless of your shot composition and ensures great focus no matter where the subject is located in the frame. The addition of the dual-cross point in the center allows for much faster and precise focusing for photographers using high-speed f/2.8 lenses.

Using the touch panel, parents can select their child on the LCD screen and the camera will remain focused on that child while they stay in-frame, ensuring sharp focus in crowds and group shots. The new AF system enables Touch Focus for shooting photos and movies in Live View. To make capturing photos even easier, a Touch Shutter function can also be enabled, whereby selecting a subject on the LCD screen, the camera will instantly take a photo, once focus is locked.

Continuous AF during HD Video Recording
For the first time in a Canon EOS DSLR, the EOS Rebel T4i includes Canon’s new Movie Servo AF for recording video. When used with Canon’s new EF and EF-S STM lenses, the camera can provide smooth and quiet continuous AF while recording video. This technological breakthrough enables the new EOS Rebel T4i to achieve AF while still retaining a DSLR camera’s signature background blur and image quality, producing stunning videos of parties, events, summer vacations or graduations.

When shooting video with Canon’s STM lenses, AF also remains silent, helping ensure you only capture the sound of the scene being recorded. The EOS Rebel T4i features a built-in stereo microphone, a first for the Rebel line, that includes an attenuator function to reduce audio distortion in extra loud situations.

Canon’s First Touch-Screen DSLR
Another Canon first, the EOS Rebel T4i includes a best-in-class Vari-angle Touch Screen 3.0-inch Clear View LCD monitor II featuring 1.04 million dot resolution for unparalleled, clear viewing. The electro-static touch-panel screen is the most advanced that Canon has released to date with multi-touch capabilities allowing photographers to use familiar gestures such as “pinch-to-zoom” and “swiping” to scroll between pictures. Camera operation has been simplified through this feature allowing for Touch Focus or Touch Shutter controls via the vari-angle touch-screen. The vari-angle touch-screen flips out to the left and rotates 180 degrees forward and 90 degrees backward, making tough above-the-head and low-to-the-ground shots easy, and allowing improved views during photo or video capture. That means the overhead shot taken in a crowd or at a graduation march just got a little easier to shoot.
