Canon has confirmed that the new Canon EOS-1D X will be going on sale at the end of April 2012. The Canon EOS-1D X will be the new flagship professional model.

We caught up with the Canon EOS-1D X when it was announced back in October 2011. It offers an 18-megapixel full frame sensor, with an ISO range that runs from 100 to 204800, 61 focus points and a new 100,000 pixel RGB metering sensor. 

It will feature dual Digic 5+ processors, offer full HD video capture and features a 3.2-inch display around the back, as well as an Ethernet connection to speed up photographer's workflows. It will cost £5299.

However, while the EOS-1D X occupies the top spot of Canon's full-frame DSLR range, rumours of the "other" full frame model won't stay quiet.

The latest reports suggest that the Canon EOS 5D Mk III will be announced on 2 March 2012, perhaps to be shown at the Focus on Imaging 2012 photography show in the UK.

Rumoured specs for the new model include a 22-megapixel sensor, the same 61-point focusing system and display. Of course, the 5D Mk III is a more compact body, as the battery grip is a separate accessory.
