This last Saturday I shot a local football passing league tournament and had a blast. I shot the first game with the 300 f/2.8 and then changed to my 70-200 f/2.8 with the 1.4x for the next two games. I then put back on the 300 and forced myself to shoot the remaining three games with to give it a work out and become familuer with it.
These first shots are with the 70-200.
These last shots were taken with the 300 f/2.8
I just have to say I love this lens (300). It's fast and the pictures come out very sharp.
