The Canon EOS 800D is Canon's update to the 750D. The camera features a new 24mp APS-C CMOS sensor, ISO25600, 6fps continuous shooting, Full HD, 60fps video recording, with built-in Wi-Fi, NFC, and Bluetooth. The 750D will remain on the market.
Introduced with the 77D and 800D is a new Canon EF-S 18-55mm f/4-5.6 IS STM lens, that is an ultra compact kit lens, that Canon say is the World's smallest non-retractable kit lens. The lens offers up to 4-stops of Image Stabilisation (IS), with improved optics, and a size that is just 61.8mm long. When used with the new lens, the camera is said to offer the World's fastest focus for APS-C ILC cameras at 0.03s (when using the viewfinder). The new lens will also be available on its own, as well as part of a kit.
A new bluetooth remote, BR-E1, has been announced, offering an AF and separate shutter button, letting you remotely control the 77D or 800D. The remote is not currently compatible with any other Canon cameras, and has a 5m+ range.
There is a microphone socket on the side, a flash hot-shoe on top, plus a built-in pop-up flash. The 3inch vari-angle touch-screen can be tilted forwards so that it can be used as a selfie screen, and the built-in guide can be switched on and off. You can watch a video, below, showing the new guide mode, as well as the options available.
