Now I photograph a lot of outdoor portrais (whole body and face) This objective proved to be a good helper I was always happy with the photos my customers at maximum aperture (f2.8), the people are very well isolated the focus is working a little slow and noisy but that should hardly disturb a the sharpness is good there is in my lens and no front or back focus also the weight of the processing and handling leaves a good impression However, this lens has a little weakness for backlit subjects on by and large, I am very pleased especially with the value
