As Photokina kicks off in Cologne, Germany, Canon has announced the December release of its smallest full-frame camera – the EOS 6D.

The 6D, whose details had been leaked well in advance of today's announcement, features a 20.2-megapixel CMOS sensor, a sensitivity range of ISO 100 to ISO 25,600 that is expendable to ISO 50 to ISO 102,400, and a new 11-point autofocus system.

Designed for "serious photography enthusiasts" the EOS 6D has a compact body similar to the EOS 60D and has become the entry point into Canon's full-frame lineup.

The camera has Wifi and GPS technology built in to make it easier for photographers to share their images as they shoot. "Images can be wirelessly transferred to external storage devices, uploaded to Facebook and YouTube, or printed wirelessly using a Canon Wifi-enabled printer," says Canon. "By wirelessly connecting to a smartphone, photographers can also control the camera remotely, adjusting shooting settings and focus before triggering the shutter remotely and viewing the captured image."

The EOS 6D measures 144.5 x 110.5 x 71.2mm, weighs 770g, and has a three-inch Clear View LCD screen, which features an enhanced anti-glare design.

Available from December, the EOS 6D will retail at £1800 (body only) and at £2520 with the EF 24-105mm f/4 L IS USM lens.

The launch comes less than a week after Nikon unveiled its own entry-level full-frame DSLR – the D600. However, Nikon's model will retail from 18 September instead of December for Canon's EOS 6D.
