Quote: Sounds good. What sport is your 'match'?
My 'normal' sport is football (the one with a round ball), but this year I shot a couple of matches of American football as well. It's a small sport in our small country, but from a photographer's point of view I found it interesting.
These ones were taken with Nikon D750 and Nikkor 70-200 VRII, some also with added Nikon 1.7x TC.
If I remember right, all of these were shot wide open, aperture being either 2.8 or 4.8 depending wether or not the TC was used.
A 70-200 lens is still too short to cover the pitch as well as I'd like, and I'm currently concidering my options. The latest addition to the list (Sigma, Tamron...) was of course the new Nikkor 200-500, which seems very interesting. I'm waiting eagerly for some test results, comparisons and pictures to show up online. And for historic reasons I'm also interested how the Pentax 150-450 fares against the others.
Weather sealing is one important point in this concideration. With the mentioned lenses, Sigma Sport is the only one which offers that option. Pentax is already out of the question when regarding sports shooting because I've already invested quite much into the Nikon system which offers vastly better AF.
For the record: coming from K-5 to D750 the AF system is from another world. I haven't calculated any persentages but the amount of in-focus images is up significantly. The focus tracking is simply amazing, whereas with the K-5 (and the old version of the Tamron 70-200) I had no chance of using the AF-C at all.
