So I've been debating between Nikon and Canon since the beginning when I bought the Canon 7D. At the time, it was basically better camera body with the Nikon vs better fast prime lenses with Canon. I had thought that the fast lenses together with the new EOS DSLR and it's new and improved AF system, I would have a pretty solid setup. 7 months later, after trying various techniques, settings, having the camera calibrated, having the lens calibrated, praying, jumping, hopping ... whatever... the camera still manages to mis-focus about 25% of the time. Mis-focusing on STILL subjects. Recently, I was able to try a friend's D3 (okay, a friend of a friend's) and was just amazed at how accurate the focusing was even in dim lighting. So last week, I decided to sell off my Canon gear and make the jump to Nikon. The end result? A D700 along with a 50/1.4G lens. So far, everything looks good. Literally. Focus is accurate, albeit a bit slower than Canon. Consistency is good. So far a happy camper. The added advantage of a full-frame sensor is also a plus. Now all that's left is for Nikon to give us some nice prime lenses. AFS 35/1.4, AFS 85/1.4 !!!
