Most of my photography has been of relatively stationary subjects, where I just use single-servo AF and either focus & recompose or move the single focus point to where in the frame I want the subject, or largely-individual sports like triathlon. But I’ve struggled getting sharp shots in team sports photography with a large number of moving people in frame.

If I try using continuous autofocus, it often focuses on the wrong subject or the background or seemingly nothing at all. If I try falling back on the techniques that work in other contexts, I usually just can’t get the shot off at the right time.

I don’t really understand the different autofocus options on my camera. I was mostly using what it calls “3D”, but I also briefly tried “group-area”. I don’t really understand how group-area differs from d9 or even 3D. And my camera’s manual doesn’t clear things up for me. I spent a little while in manual autofocus with a fairly closed aperture, by using autofocus and then switching to manual and leaving it untouched; but this only worked when play stayed roughly the same distance from the camera for a while, so didn’t really scale well.

Separate from the focus question, I spent the afternoon shooting at 1/1600. I’m not completely sure if this is fast enough, and maybe some of the blur in my photos is actually better explained by camera shake (shooting at 200 mm on a 1.5x crop sensor) or movement of the subjects. I suspect it’s probably not relevant, but I thought I’d mention it just in case.

What’s the best advice for how to get sharp shots in team sports photography?

    Shutter speed is only half the equation. What’s your aperture set to? If you shoot wife-open (lowest f number) on a fast lens (e.g. f/1.4), the area that is in focus will be too shallow, and the camera’s AF will have trouble locking onto fast moving subjects. Step it down to f/4-f/8 to get more of the area in focus,and get the shutter even faster to 1/4000 or even 1/8000 to freeze the motion. Of course if you’re shooting indoors that would require cranking up the ISO to compensate, which may introduce noise. It’s a matter of finding the right balance.

      So, ideally I’d like to keep the aperture wide precisely because I want the low depth-of-field. As it happens my lens isn’t a very fast one (55–200 mm f/4.0–5.6), and a fair few of my photos were stopped down to around f/6–8 anyway, especially the ones where I had switched to manual, but the reason I was asking for assistance on how to nail the focus is to help get the sharpest subject I can and be able to keep a nice soft background.
