Rented for one day. In my opinion the best portrait lens for canon for shooting outdoors. A slightly longer focal length than the 85mm that everyone is used to adds some flair to the photo. The bokeh is chic, aperture and FR allows the object being shot to stand out just anywhere, even in the crowd, bushes, and generally anywhere. Autofocus works with this lens just fine out of 200 frames, it inaccurately hit somewhere around 10-20. It probably makes no sense to take a crop. Unless it will be possible to shoot large birds.
