by "faster AF" does it mean how fast and accurate the AF system takes to focus on the right subject? Because I just thought, if a "faster" AF system actually drives the screw mechanism faster than older AF software can...
I guess, boiled down, there are two main factors. Firstly the AF speed of the lens itself, i.e. how long it takes to go from MFD to infinity focus, and points in between. Secondly, the capability of the camera body to judge and aquire proper AF. My current thinking is that they are both important, but the Camera body is the most important. I feel this way because when I had my D700, bacially any lens I tried on the D700 accurately aquired focus as or more quickly than any lens I tried on my K20D / K-5. With the D700, I basically left it on AF.C all the time. Even when shooting my favorite lens on the D700, the Tokina 35 macro, the AF.c performance was as fast as I could want it to be.
Now, I am not slamming Pentax. I actually only own only a Pentax body right now. Pentax has a lot going for it. But because of the AF performance to a greater extent, and the availability of FF bodies to a lesser extent, I will end up being a dual system, Nikon and Pentax, shooter. I had been planning on waiting until later in the year to make a decision on my next camera body, but the D800 is really calling my name.
