I'll post what I said too I suppose, I like what I wrote
Shanny, I jumped ship due to the worst customer service I've ever experienced. Let's just that part out of the way for starters.
Ok now that's been said, Nikon has been by far my favorite system to shoot with simply due to the bodies and terrific quality of glass. In my opinion, there's no bad Nikon glass. But, now I think that there is no such thing as bad glass. More on that in a bit. To be fair to Canon though, I never used a 1DsMarkIII. But then, the D700 is every bit the 1DsMarkIII minus the cost. Maybe if I would have sold the MarkIII and 5DII for a 1DsMarkIII, maybe I'd still be shooting Canon. Well maybe not, again it was the service.
I've used every gambit of body almost, almost every gambit of glass. When I look back at my Rebel XT shots and my current D700 shots, what's really changed is how I shoot and getting the most out of every shot. Give me back my Rebel XT and I will take good shots with it. Give me my D700 and I will take good shots with it. What Nikon has never done though, is let me down in their mechanical performance. I can't say the same for Canon.
That said, I'm bailing on DSLR shooting for a while to free up funds to get out of [SUBstantial] debt and since I have little kids, the shooting time is less. I've grabbed a Lumix-GF2 and when that comes in, I'll take good shots with that too. When I come back to DSLR's, which I will, I will shoot Nikon. Not because the picture is better, because they have worked every time. Had Canon not ever let me down it would be a harder decision. I can go better full frame with Nikon for cheaper though, and that would probably drive it. If I could get a 1DsMarkIII for the same price as a D700, I'd probably go Canon.
Admire your photographers for what and how they see their subjects. Admire them for mastering light and driving hundreds of miles to not get a keeper shot. Don't admire them for what they shoot with.]
