Hi folks,Canon EOS T4i / 650D review
The New EOS Rebel T4i DSLR Camera Puts The Power And Creativity Of DSLR Stills And Video At Your Fingertips
Silent and Continuous Autofocus in Video, The EOS Rebel T4i Lets People Re-Live Magic Moments Through Stunningly Crisp Video and Incredible Stereo Sound
LAKE SUCCESS, N.Y., June 8, 2012 – Canon U.S.A., Inc., a leader in digital imaging, today announced a new flagship model in its most popular EOS Rebel line, the Canon EOS Rebel T4i Digital SLR Camera. 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.
Improved Imaging Performance Features
The EOS Rebel T4i helps novice photographers capture great images and video, even in low-light with a range of new and upgraded modes:
- Handheld Night Scene
- Video Snapshot
- HDR Backlight Control
- Scene Intelligent Auto
- Multi-Shot Noise Reduction
Canon's new shooting modes (Handheld Night Scene, HDR Backlight Control and Multi-Shot Noise Reduction), take multiple pictures, and combine them - in camera - to help capture a wider dynamic range, minimize the image grain or noise, and produce more vivid colors so landscapes and city scenes are as breathtaking as when seen in person.
Families have enjoyed coming home from a vacation or outing with a fun, short Video Snapshot highlight reel shot on their Canon camera to share the full story of their adventure. Now with the EOS Rebel T4i users will also have the option to delete, cut or re-order the clips before exporting the Snapshot album to post or share.
Canon's Scene Intelligent Auto mode - the "green" mode on the dial - analyzes the scene being shot, taking into account faces, colors, brightness, movement and contrast, to select appropriate camera settings and help produce the best possible image. This mode has been enhanced to deliver the best possible exposure, particularly when shooting in low-light.
New STM Lenses and Accessories
To leverage the unique, new shooting functions of the EOS Rebel T4i, such as EOS Full HD Movie with continuous AF, Canon is introducing two new unique lenses, the new EF-S 18-135mm f/3.5-5.6 IS STM lens and new EF 40mm f/2.8 STM lens. Both new STM lenses includes Canon's new Stepping Motor technology, which allows the lenses to smoothly and silently focus, and when used in combination with Canon's new EOS Rebel T4i Movie Servo AF feature, achieve continuous AF while recording video. The new stepping motor technology in both lenses quietly focuses allowing the EOS Rebel T4i's stereo microphone to only record the sounds of the scene being shot.
The versatile EF-S 18-135mm f/3.5-5.6 IS STM lens offers the right combination of size, weight, image stabilization and focal length, allowing photographers to capture wide-angle or telephoto photographs and video. This lens is a great option for photographers who may only want to carry one lens with them for both wide landscapes, and close-ups. Appearing for the first time in a Canon EF lens is Dynamic IS (Movie Shooting Mode only) that uses a wide image stabilization correction range to help ensure steady video even when shooting while walking.
The new EF 40mm f/2.8 STM lens offers an ultra-slim, lightweight design that helps photographers avoid overwhelming their subjects with a large lens and to remain discreet in sensitive shooting situations without compromising performance. The "pancake-style" lens boasts an aperture of f/2.8 making it an ideal lens for capturing portrait stills or stunning video. The lens is under an inch thick when attached, making it easy to carry and fit conveniently into a purse or pocket.
The EOS Rebel T4i is also compatible with Canon's previously introduced GP-E2 GPS Receiver that can be mounted to the camera's accessory shoe. The GPS unit was created to serve outdoor photographers; it records shooting locations including latitude, longitude and altitude, as well as camera direction. A Logging function can tell how far a photographer has traveled as well.
The EOS Rebel T4i Digital SLR camera will be available at the end of June for an estimated retail price of $849.99 for the body alone; $949.99 bundled with an EF-S 18-55mm f/3.5-5.6 IS II lens kit and a Movie Kit bundle for $1199.00 with the new EF-S 18-135mm f/3.5-5.6 IS STM lens.
The new EF 40mm f/2.8 STM lens and the new EF-S 18-135mm f/3.5-5.6 IS STM will also be available separately at the end of June at an estimated retail price of $199.99 and $549.99 respectively.
There's also a separate press release for the new lenses which you can read here
. The UK product page for the 650D is also up now (here
) so you can browse the detailed specifications.
A welcome addition to the entry level line-up. My personal take, and I'm pretty much outside the Canon fan base now, is that it's disappointing that, by implication, none of Canon's previous EF and EF-S lenses are ever going to be particularly good for AF with video, hence Canon's introduction of the stepping motor STM lenses. Otherwise the specifications are unsurprising but welcome upgrades with one exception...
factor for me is Canon's inclusion of pixels on the sensor dedicated to phase detect AF, similar in concet to what we have already seen with the Nikon 1 system. Apparently Canon uses the sensor based PDAD pixels to get the focus close, and without gross errors such as when CDAF systems guess wrong, and then use conventional CDAF to nail the focus more precisely. From EOS 650D Technologies Explained
("DOC" file) we have "The EOS 650D’s APS-C sensor features a new Hybrid AF System, which uses the central pixels of the sensor to enable continuous AF when shooting in Live View Mode or when recording EOS Movies . The Hybrid AF system uses a combination of both phase detection and contrast AF to ensure quick and accurate auto focus
". Of course that rather begs the question of why Canon has continued to bother with a mirror, conventional PDAF chip and an optical viewfinder rather than put more of those PDAF pixels on the main sensor but I guess some folks still like their flappy mechanicals. More seriously, it seems that Canon suggest they still get better performance from the regular (60D based) PDAF sensor with current EF/EF-S glass.
But the key technologies are now all in place for Canon's widely expected entry into the CSC (mirrorless) market expected later this year.
