I purchased this lens from a forum member less than a month ago to shoot my son's last Jr High basketball tournament of the year;
Exposure Time 1/180s (0.0056)
Aperture F/2.0
ISO Equivalent 800
Also took a shot at my first HighKey photo;
Exposure Time 1/180s (0.0056)
Aperture F/8.0
ISO Equivalent 400
A portrait of a friend's daughter;
Exposure Time 1/200s (0.0050)
Aperture F/4.0
ISO Equivalent 400
I had competition from an aspiring young photographer at the games;
Exposure Time 1/160s (0.0063)
Aperture F/2.8
ISO Equivalent 400
How can I not be happy with the results of this lens.
