I'm on the case. Thanks for the info.

This photo from an Under-11s soccer match was shot with my Nikon D600 and Nikon 80-200 f./2.8 using the 3D Auto-focus mode.

Details: Raw; Manual mode (1/500s, f.6.7); Auto-ISO (180); cropped to A4 aspect ration in Lightroom.

The picture shows my grandson (in blue with the ball) reacting to the referee's whistle having just been caught offside.

You can see that the focus is not where I would have wanted it. Straightforward user-error. Wrong choice of AF mode.

But the body language of my grandson's team-mate ensures it's a keeper!

I agree. Thanks for the advice.

Mrs LBWR works for the University of Birmingham and the educational discount brought the price down to £60.
