Input:
I love how perfect this lens is for photographing and even filming sports. I am not a fan of the auto focus mechanism, but otherwise it is perfect. The zoom is deep enough for all kinds of fields/ action shots. It's small enough to not weigh down a neck strap or bag, but does everything I need it to do.
