I really enjoy how it is neutral about the out of focus areas. For a close-up, such as the one attached, I prefer shooting at f/5.6 or f/8, but here the lens did really well at f/2. Still nothing massively distracting about the background.
I enjoy this lens a lot, and often it's the only lens I bring when I'm out photographing.
