Yes, I would recommend this to a friend

Fast / Accurate Auto-Focus; Fast Shutter Speed; Good Image Quality; Good Image Stabilization; High ISO Performance; Quiet; Tilt /Swivel LCD

Short Battery Life; Small LCD Screen

Almost the same menus as 1DIII, which I have used for some time and like. Requires more care as the detail of the image is so high. Just got back from a week in Death Valley for flowers, shots look wonderful. Colors are very good. Data size get large in a hurry, I download to my laptop everyday.

Best user interface; Good Battery Life; Great Resolution; Weather proof

The EOS-1Ds Mark III is the seventh Canon professional EOS-1D series digital SLR, although only the third of the 's' suffix sub-category which indicates a full frame sensor. Three years since the last EOS-1Ds, the Mark II, the Mark III pushes digital SLR resolution over the twenty megapixel barrier...

Significant upgrade to the Mark II that improves almost every area of performance without 'reinventing the wheel, Better ISO button placement, new joystick, new AF point selection method, ISO in the viewfinder; all help faster more intuitive operation and mean you less often have to take your eye

How many people are going to spend £5,500 on a camera? Even more importantly, how many enthusiast photographers rather than pros, will fork out that amount of money and justify it to their partners? Probably not too many, but Canon's flagship DSLR is still worth looking at for a number of reasons.
