I went to the West Virginia - Ole Miss basketball game at the WVU Coliseum on Dec 23. I had some far away seats, two rows from the back of the upper level. But even at that distance (with the shots cropped to make up for the fairly short 135mm), the DA* 50-135 really came through. I've never gotten indoor sports shots like this before with my slow telezooms.
I was sitting about 175 feet away from mid-court.
Tip-off: 1/400s, f/3.2, ISO 400, 135mm
Wellington Smith finishing a dunk: 1/400 sec, f/3.2, ISO 800, 135mm
Wellington Smith for three: 1/400s, f/3.2, ISO 400, 135mm
"Truck" Bryant fighting hard: 1/400s, f/3.2, ISO 400, 123mm
