Stick,

Since you're gunning both the 1DS and 1DMK3, is there much of a difference in IQ. Or is it akin to picking gnats out of pepper? I'm assuming for wildlife and action shots the 1DMK3 would be the huckleberry due to the faster FR and crop factor?

Any preference as to the BIG brick 24-70mm or 24-105mm?

Obliged.
