The Canon EOS 650D (known as the Kiss X6i in Japan and the Rebel T4i in the Americas) is an 18.0 megapixel digital single-lens reflex camera (DSLR), announced by Canon on 8 June 2012. It is the successor to the EOS 600D/Kiss X5/Rebel T3i and was later superseded by the EOS 700D/Kiss X7i/Rebel T5i. Sales began on 15 June 2012. At introduction, recommended retail prices for the body were US$849.99, £699.99 (including VAT), and €839.99 (including VAT).
Features
The 650D is the first Canon DSLR that has continuous autofocus in video 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 650D. DPReview noted that the Hybrid AF system was similar to the focusing system of the Nikon 1 mirrorless cameras.
The 650D 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 9Â points are cross-type, as opposed to only the central point in the 600D. The central point is also dual cross-type (i.e., also sensitive to diagonal lines) at f/2.8. The EOS 650D is built with two new shooting modes designed for inexperienced photographers. The Handheld Night Scene mode and the HDR backlight mode. The Handheld Night Scene mode reduces the risk of blur while taking nighttime shots without a tripod while the HDR backlight mode uses Canon's patented multishot system to combine three images into one, balancing both foreground and background exposure. 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 (25Â Hz) and 30p (29.97Â Hz) with drop frame timing
- 720p HD video recording at 50p (50 Hz) and 60p (59.94Â Hz)
- 480p ED video recording at 50p (50Â Hz) and 60p (59.94Â Hz)
- 5.0 frames per second continuous shooting
- ISO sensitivity 100â€"12800 (expandable to 25600)
- 3.0-inch Clear View II LCD touchscreen with 1.04-megapixel resolution
- 9-point autofocus system, all cross-type
- 63-zone color sensitive metering system
- Built-in Speedlite transmitter
- The camera is compatible with Canon's latest radio-controlled flashes, but the built-in transmitter is infrared-only.
- Popup flash
- Built-in stereo microphone
- 3.5mm microphone jack for external microphones or recorders
One feature of the 600D missing from the 650D is the former's 3â€"10× digital zoom capability when shooting 1080p video.
Ergonomics
The 650D has roughly the same dimensions as the 600D, and apart from the touchscreen has largely the same physical controls as previous xxxD models. One notable difference is that the two-position power switch of the 600D is replaced with a three-position switch on the 650D, with the added position used to activate the video shooting mode.
Speed
The DIGIC 5 processor, used for the first time in a consumer-level Canon DSLR, allows for a significant increase in continuous shooting from the 600D of 5.0 frames per second, up from 3.7 frames per second. The 650D is also the first Canon DSLR to support the UHS-I bus . The 650D's autofocus during live view mode is approximately two times faster than the 600D.
