1Ds Mark II

This is a camera...aside from 4fps instead of 8.5fps, this camera out performs the 1D MkII N which is a excellent model as well. Gives the ability to make the camera into your own professional shooter, with use of enormous amount of customable settings. I own the 1D MkII N as well and use it for super fast shooting(8.5fps) but this is my main tool with double the MBs at 16.7, and color and IQ exquiste....

I've had my 1Ds Mark II for a couple of years and have had excellent service from it. It will read an write to every data card I've tried. Read and write are fast. Focusing is fast. Viewfinder is very bright. It requires the best Canon L lenses in order to make use of the high resolution sensor.

I've had the 1DS MKII for 2 years, and it has been a real pleasure to use, it's been bumped around the Yorkshire Dales, dropped on rocks a number of times but just keeps on going, been back to Canon once for a service.
Image quality is amazing, low noise at high ISO, bright viewfinder, intuitive controls (except mirror lock-up)
Highly recommended, best DSLR on the market.

Rubbish!!! had mine back to manufacturer several times, due to data transfer problems, and lost data. Selling up and going to Nikon
