I'm starting to get frustrated with Nikon, for a few reasons... 1. Slower autofocus I've missed many shots because of it. No matter how many times I try to keep myself away from Canons, I'm always drawn towards their incredible autofocus speed. It's not just that the lenses have faster AF overall (even non-USM lenses are faster than Nikon's "fake" AF-S lenses), but the Canon bodies seem to initiate AF with zero lag, where Nikons have a very slight lag that makes a very big difference for shooting anything that movies. 2. Crappy warranty service Sure, the warranties are two years on bodies and five on lenses. But, what good is that if you have to be without your gear for three weeks or more (two, if you're lucky) at a time? I need a particular lens in two weeks, which is broken at the moment. Will I have it back in time from Nikon? Who knows!? From what I read, Canon's turn-around time is a week or less. 3. Quality control issues I have now had two lenses fail me a total of four times in less than a year. Seriously. Is this normal? For any brand? I'd be looking at a 40D setup. The main thing holding me back from switching is, obviously, the cost involved in doing such a thing and also to Canon's inferior handling. I could probably get used to the controls, but I'd have a niggling feeling that a D90 or D300 would be so much faster at adjusting important settings (WB/ISO/QUAL/AF/METER/DRV/etc). Just wanted to throw that out there.
