I'm trying, honest I am. I'm trying like an addict trying to cold-turkey heroin. As great as the D800 is I just can't bring myself to give up the D3s. When the grand-kids are playing in the family room, ambient light, cute as a bug, I grab the D3s. Auto iso at 6400 max, CH, 24-70 at 5.6, grin at max-wide.
Tomorrow, I'll give it up tomorrow ... really ... I will. OK, well, maybe when the D4s is released.
