No no, but see the guy with who i talked about Nikon stuff, had Canon 1D mkIII before he changed it to Nikon D3 - because he realised that there is some software problem with 1D. He did normal test photos, so he saw the difference. He was using something like 4 different copies of 1D mkIII, every has the same issue. And i feel the need for maximum sharpness

Really.
I did some photos last time with 1D also. And i also realised today that what he told is right.
Of course situation changes all the time, there are new models each year, but i'm looking on how it is in
this moment, because i need to buy a camera
now, not in next 12 months or so. So i am interested into the best choice for now

I really don't wanted to change the system, but i started to think deeper about technical details & possibilities of both C & N. Still, i do not have too much of the Canon equipment, so it will not be really much "pain" for me. I just heard too much opinions about new Nikon cameras, and comparing this to everything what Canon makes nowadays (50D, 5DmkII) i see some bigger postives on Nikon side. Still i have to meet with my friend who have D3 to play with this camera, and see if i even like the Nikon's feeling.
But, first of all, let's compare 'pro' models from both Canon & Nikon. I leave D3 because it's too expensive anyways for me (i don't have any Nikon lens so it should be necessary to buy also the lens, so with D3 it will be horrendous money).
Canon 1D mkIII - cropped sensor, problems with sharpness, even mkIIN is sharper. 10fps, VERY good AF, ISO up to 3200 (useful).
$3,800Canon 5D mkII - Full frame, average AF (in darker places - can be really bad), sharp images but depends on lenses, because this body have too much MPix, very slow burst. And for god's sake - why HD movies??
$3,000Nikon D700 - Full frame(!), very good AF (but in darker places can be a little bit slower), useful ISO up to 2000, 8fps(!), very sharp images(!).
$2,500 with battery-grip. (+ some two Sigma's or Tamron's which give me the range of 15/16mm to 200mm for the beginning. It would everything cost the same as the body only of 1D mkIII).
D3 is nearly the same as D700, but bigger & heavier, sensor is VERY similiar. And it have two CF card slots instead of one slot in D700. And cost similiar to 1D mkIII ($3,800 body only).
