Re: Busting the Lens dictates Focus Speed Myth

In simple terms there are two things that affect the focus speed and this from my experience

1/. type of focus drive

2/. camera type - same  lens on a 10D is way slower than on a 1D going back a few years. The higher quality cameras appear to have better drivers.

My experience is 10D, 40D and then the 7D. I have discussed focus speed of the 50 1.4 with a pro and said his was blindingly fast where as on the 10D it was very slow.
