Optical design

Great choice mainly for good light conditions Has 7 aperture blades, mid-grade lenses usually have this amount of blades. Having rounded blades provides out of focus circle shape closer to a circle.

Physical characteristics

Weights 450 grams so plan ahead, carry only if really necessary. With a lens filter diameter of 72 mm you are one step from the next standard filter size, buy step-up ring and bigger filter but you can chose from plenty options. 78 mm long, requires consideration if you want to carry in the camera bag.
