I think we can confidently declare that Canon have risen to the challenge of asserting their status as Numero Uno in relation to Nikon and Sony.
The 5D MkII hasn't got everything, however. I don't see auto ISO in relation to a specified aperture and shutter speed. The lack of such a feature has sometimes got me into trouble when, for example, I'm trekking along a mountain track with camera in 'aperture priority' mode, and a Tibetan horseman races around the corner.
I've got no time to change ISO to accommodate a higher shutter speed and the opportunity for a sharp shot is missed.
I shall appreciate the HD video a lot. I've often wondered why manufacturers of DSLRs have not included such a feature.
In these times of impending recession and financial turmoil, I think Canon have positioned themselves well. This camera will sell like hot cakes.
