Excellent lens... Respectable at 1.8, but really good at 2.2...
Good build and better than expected AF... feel like ring USM most of the time for me even though its not..
The build is good enough for sure, and the bokeh is nice with the 8-blade aperture design.
I was going to get the nifty fifty, but for $225, I get another full stop of sharpness, better build, better bokeh.
Very happy with this lens.....
