I just got my D300 too! after buying 50D in Sept, selling it in oct, and finally got my favourite nikon D300. Of course not going to jump ship this time, why i changed camp is because 1. I grow up a Nikon fan, 2. canon image quality sucks.
But after testing the 51 point AF i was slightly disappointed. After test many times, i realised that the 51 point autofocus speed is slower than using single point, am i wrong? Cos when I used my canon 50D with 17-85 IS USM lens, the focus speed is the same whether I used the a single point or the 9 point autofocus. And the focus will be locked almost immediately under normal indoor florocent light. I tested using the D90 18-105mm AF-S ED VR DX lens.
So, am i facing this alone? or am i expecting too much? ;p Or i thought i should be, since it by right should be better than Canon. Afterall, D300 scored 9.5 for performance in DPreview while 50D only scored 9.0. Or is it the lens that is the limiting factor? But if that is the case, still there shouldn't be any difference between single point and 51/21/9 point.
But generally still love my new toy. just that maybe next time I will need to use single point focus more often.
Lol, like you suggested its 9 AF points on the canon versus 51 AF points on the nikon. If you are using the 51 point auto auto focus(yes 2 auto cus its the auto mode of the auto focus), the camera has information from 51 AF points to process, so the camera thinks where to AF first(which is the intial lag time) then it focuses.
Also Canon's AF is faster than Nikon's but i feel that the 3D auto focusing on the nikons'(d90 and above) are really good and the 51 points of AF offers alot of flexibility (ESP when the AF points cover 50% of the view finder).
If you really need brute AF speed, AF on a line or a something like the side of a persons hand or what ever, and use single point AF, it will auto focus very quickily
