@king1: if naa ka plan mo shift boss, dont waste ur time if money is not a big issue para nimo...im sure happy rapud ghapon ka watever system imo mapilian/upgrade, just the fact that a strong force is pulling u to the darkside...i was once on ur shoes boss...(been a canon user before...invested a lot of L lenses,with 2 bodies 5dmk2 and 40D)...pero pag shift nako sa nikon (im using D700 and D3s right now), been happier with the contrast,high ISO, AF,etc.
just an honest opinion...but still u cant go wrong with the two
buy what ur urge dictates u...in the end, ikaw ra ghapon mo gamit...
