I share Guy's preference for primes, it seems that quite a few of us prefer primes. I still mostly use my old Nikkors from 35 years ago. My lenses of choice are a 300mm, a 200mm f/4 (lighter and with the ISO capacity of the current d700, fast enough) 105mm, 55mm micro, and for wide I am using a 28mm which is sharpest at f/8. However I would be interested in the 24mm iterations as they seem to be as sharp as my other lenses. When the dust settles in the next six months I will also get a d800(uncertain if I want the d800 or the E, I suspect the E) But I foresee that camera being strictly a tripod mounted camera. Since I already do a lot of tripod work for me lack of VR in the times that I handhold things is never an issue. I either use flash or ridiculously high ISO's on the d700 (got to love that capability) I can see why for a lot of working guys the two cameras would just about cover most any situation.
I am looking forward to taking the new camera out for a test spin and see what I can wring out of it. I would love to have a camera out-resolve my lenses, I have never had that experience in 50 years of 8x10,4x5, 2 1/4 or 35mm work have I ever had a camera/film or now digital out resolve any lens as long as I used the optimal f/stop. Equally I have never had a lens that was optimally sharp at every f/stop. It is funny, as long as I can remember this one subject has been periodically the hot topic. Every time I get a new camera, the first thing I want to see is just how sharp is it really? It has to be genetic predisposition, those who become photographers need to smell the print and now pixel peep. ( And I am guilty, guilty, guilty.)
As an aside, my wife whispered to me in the dark one night recently, why don't you buy the new camera?
You might be surprised what kind of an effect that can have.
Though I wonder if it might work the same in reverse?
