Nikon 300 f/4 focus speed question

Discussion in 'Lens Lust' started by jklofft, May 30, 2007.

  1. I’m looking to add a 300mm lens to be collection. My primary use would be youth sports. I’ve got the 70-200 VR, but have found it to be a bit too short. I’ve added a 1.4TC, but when I’ve done that, the AF speed on my D200 seems to leave me with too many soft shots. I can’t be sure if the softness is due to the TC or the AF slightly missing. I know that the 300 f/2.8 VR (or Sigma 120-300) would be perfect, but given the more limited use, I can’t justify the cost.

    So, my main question is this: Is the focus of the 300 f/4 about as fast as the 70-200VR (without TC) on a D200? Thanks.

    Are you talking about the 300mm f/4 AF-S? The auto focus on that is very fast, but obviously wouldn't match a f/2.8 lens when it gets darker.
  3. Sorry, yes the AF-S model. I'd mostly be using it in hand-held situations with a shutterspeed at 1/500th or faster.

    I've only used it once but I found the AF to be very fast and very sharp in good light, my friend has since sold it and I haven't had a chance to compare to my Sigma 70-200mm f/2.8, but it seems just as fast or faster.
  5. I just bought a 300/4 AFS for similar reasons. It is sharp and the focus is VERY fast, at least on a par with the 70-200VR if not faster. I haven't tried shooting sports with it yet but I can't wait to try. It's a bit slower with a TC1.4e attached but still very sharp.

    I Don't Quite Agree

    I own a 300 f4 AFS and love the thing...and I do shoot lots of moving targets with it (mainly flying feathered creatures).

    That being said, there is no way it's as fast as the 70-200 either naked or with a TC14EII on it. (I used to own a 70-200 but no longer have the need for one)

    I've also shot kids soccer and a little bit of high school football with it and as long as you have your camera focus set up correctly, it works just fine.

    It is IMHO, every bit as sharp as the 70-200 and I also found it to be slightly more contrasty as well.
