The first Canon EOS 650 was a 35mm single-lens reflex camera introduced in 1987 to celebrate Canon’s 50th anniversary. It was the first EOS (Electro-Optical System) to support autofocus and to use the then-new EF lens mount. Twenty-five years later, its descendent the EOS 650D succeeds it by becoming the first Canon EOS model ever to feature a dual AF system and to offer touchscreen capability. Armed with a new hybrid CMOS sensor, the DSLR is capable of both contrast and phase detection autofocusing. Using a super fast Digic 5 processor belonging to Canon’s more expensive models and its 18MP Hybrid CMOS sensor, the 650D allows you to make full HD 1080p video recordings while maintaining constant autofocus tracking. This translates into sharper stills as well. The new 3” Vari-angle Clear View LCD II touch screen supports simple multi-touch gestures such as pinching and swiping. You can even select AF points in Live View mode for tracking faces and objects, and refine image settings using Quick Control. The camera will be available from June 15 and will cost about £800 GBP (approximately $1,235 USD) kitted with the standard EF-S 18-55mm f/3.5-5.6 IS II lens. In the U.S., the Canon EOS 650D is also known as the Rebel T4i.
