When I scan the list of Nikon prime lenses, esp. 50 f/1.4, 85 f/1.8, 135 f/2, I see none of them have the ultrasonic AF-S focusing system. In fact, none of Nikon's primes lenses do. Does that mean that none of the Nikon primes will focus as fast or accurately as Canon's 85 f/1.8 or 135L?
I'm mainly interested in sports photography.
