Just wondering, I am thinking more and more from my experience shooting basketball under the hoop that my 50/1.8 may be faster focusing than my 17-55AF-S and definitely faster than the 70-200 This is on a D2H Anybody care to comment on this? I am thinking the brighter viewfinder, the larger glass, perhaps this allows faster focusing? (at least when coupled with the powerful CAM 2000 of the D body)? This is not a scientific opinion, just one that is slowly forming as I shoot more events, anybody else have an opinion on this? Anyway I ponder this out loud as I think about "upgrading" the 70-200 with an 85/1.4 Incidentally I use a 50/1.8 and I find it very quick and VERY accurate to focus (I was shooting at f/2.2 which can be brutal on DOF and it was really onthe money with focusing), is the 1.4 version faster?
