I love this lens. I also have the FA43, FA77 and DA*16-50, and have had the FA50, DA*50-135 and DA 70 in the past (lenses to which it is often compared), but this lens has made it on my camera more often than any.
The rounded blades really do make for really smooth bokeh--everybody talks about wide open performance when they compare it to the FA50, but once you start stopping down the contest is over.
I paid more than I would have today. But I think it's worth every penny. Never any issue with SDM. Maybe a little more audible than the 16-50.
