The Canon EOS 650D, known as the Kiss X6i in Japan or the Rebel T4i in the Americas, is an 18.0 megapixels digital single-lens reflex camera (DSLR), announced by Canon on June 8, 2012. It is the successor of the EOS 600D/Kiss X5/Rebel T3i and is the predecessor of the EOS 700D/Kiss X7i/Rebel T5i. Sales began on June 15, 2012. At introduction, recommended retail prices for the body were US$849.99,£699.99 (including VAT), and €839.99 (including VAT).
The 650D is the first Canon DSLR that has continuous autofocus in video mode and live view, which Canon calls "Hybrid CMOS 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 CMOS 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 CMOS 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 9 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.
