Nikon D700 cameras are on eBay at Â£1700ish. Gentlemen....start your wallets! My D40 let me down for the first time ever in flashless, low light, hand held the other day (cue the 70-200mm f2.8 Nikkor) . I anticipate a lot of this kind of photography in the future, so a camera that effortlessly copes with much higher ISO without discernible noise, and gives the full benefit of wide angle sounds the way ahead. Anybody got three grand I can borrow? Dave. P.S. Clueless mincing pansy Canon users need not make flippant remarks (you know who you are). How much do you have to pay for full frame?
