    I was wondering which lens focuses faster. I am going to shoot a triathlon race and I have the nikon 70-200 VR and also have access to the 300 f/4 the latest edition and was wondering which one focuses faster or are they the same?

    I could bring both but I was planning on bringing my 14-24, 24-70, 70-200, and a flash in my bag..I could bring a bigger bag and lug around the 300 but I prefer not too..

    On my D2x and D300 they are pretty much equal. The 70-200 should have a slight advantage in that there is 1 stop more light hitting the AF sensor and AF sensors work better the more light they get. Another consideration might be the size of the subject in the VF, if it's small (like it would be at smaller focal lengths) the af sensor will have more trouble locking onto a smaller target.
     
  3. 70-200 VR. It's a 2.8 and AFS should AF faster. It sure does against my 200-400 f/4.

    Thanks..I'll just stick with my 70-200..And Johnathan f/2..I went for your advise on one of my post to get a 70-200 f/2.8...
     
  5. I actually gave practical advice? That's a first! :biggrin:

    Congrates on the lens. The 70-200 VR is the best lens to own in my opinion. I use it more than any of my lenses. In fact, it's probably made me the most money throughout it's life time. Mine is so beat up though, I've dropped it 3 times and parts of the barrel are warn to the bare metal! Glass is clean and sharp, I love my 70-200 VR!
