Mount!

From an IRC discussion: I'm veeeeeeerry close to supplementing my Sigma fixation with something more conventional, either a Nikon D3 or Canon (not sure; probably 1Ds Mk III) full-frame DSLR with x lenses of which one is a tilt-shift 24mm. Both Canon and Nikon have almost identically priced TS lenses of similar spec, so it really is a case of choosing a mount and sticking with it.

The D3 really has my attention; I've seen the results and know the higher ISO speeds are useful. But I'm curious about what my friends are using and how much lens demonstrating/sharing and the like may be possible.
