I guess you can tell from my signature which camp I'm in. The first SLR I ever picked up was a Nikkormat FtN, followed closely by a Nikon F-FtN. Unfortunately, neither of them were mine and I suffered through a succession of cameras before winding up with an F2, a 55/1.2 and an 18'/2.8. I was doing a lot of concerts and nightclub shooting at the time and the system worked for me. Got married, the first child was on the way, the guitar paid the rent one month and the F2 the next two...
Last year, an old friend called up and offered me a D7' and a couple of lenses at closet-cleaning prices so I bit. It's been downhill from there. After getting the D2'' I was amazed at the great MF glass available for a proverbial song, so I picked up on a few nice pieces. And the zooms were amazing! Nothing like the old 43-86 everybody used to laugh at! Anyway, after having learned more about the new cameras and what they can do, I'd honestly have to say it would be a hard decision for me to choose objectively between Nikon and Canon. Both make great gear, Canon has more choices in glass but I guess I'm a Nikon person by heritage and pretty brand-loyal. I could nit-pick if I wanted but I'm sure you Canon users have your own set of minor griefs and we both have great glass and great bodies so what's the fuss? Either beats pushing Tri-X to 12'' any day.....
Ian, we should get together and play "gear-swap" for a day. By the time the Petit LeMans rolls around again, I plan to be there with a D3 and a 2''-4''VR, it might make for an interesting weekend!
