Canon EOS 5D Mark II
Price: £1,340/AU$3,600/US$2,200 (body only), 21.1MP, HD video: 1080p
Now that the Canon EOS 5D Mk III has been introduced, the Canon EOS 5D Mk II can be bought for a bargain price.
So if you've always wanted to experience shooting with a full-frame camera then there's no better introduction than this superb camera. (Note, it takes EF lenses only, not EF-S).

Canon EOS 6D
Price: £1,650/AU$2,300/US$1,800, 20.2MP, HD video: 1080p
Wi-Fi technology is slowly appearing in compact cameras and CSCs, but the Canon 6D is the first DSLR to feature it built in, along with GPS features. A 20.2 megapixel full frame CMOS sensor combined with a Digic 5 processor enables a native sensitivity range of ISO 100-25600, which is great for low light and landscape work, but can be extended to ISO 50-102400 if necessary.
There's no doubt where the 20.2MP Canon EOS 6D is aimed. With some professional features stripped, you're left with a camera finely tuned to the needs of the enthusiast, capable of taking photos rich in colour and tone.

Canon EOS 5D Mark III
Price: £2,340/AU$3,600/US$3,500 (body only), 22.3MP, HD video: 1080p
While it might not have the headline-grabbing 36MP pixel count of the Nikon D800, Canon's latest full-frame camera has lots to offer enthusiast photographers. For a start it has the same 61-point wide-area autofocus system as the flagship Canon EOS-1DX. This is a big improvement on the Canon EOS 5D Mark II, which has nine user selectable AF points and six assist points, giving a total of 15.
We also really like the 5D Mark III's in-camera HDR system that can record all three bracketed images (in raw and JPEG) format as well as the merged image.

Canon EOS 1D X
Price: £4,850/AU$7,300/US$6,800 (body only), 18.1MP, HD video: 1080p
The 18.1MP full-frame sensor can churn out images at 12fps (14fps in High Speed mode) and offers other mind-bending features such as extended sensitivity up to ISO 204,800 and a 61-point autofocus system. The Canon EOS 1D X is suited for us by professional photographers working in the studio, out in the field or a mix of both. A true workhorse. (Note: it takes EF lenses only, it's not EF-S compatible).
