I got my objective today and can only say - WOW! Maybe I caught a very sharp part, but it just does not remain a point for criticism. Max. That's just no special macro lens. The SDM AF is awesome and fast! (I had a Canon USM L 24-105 with a Canon 40D and was equivalent to one-but also much higher price!) Vigiettierungen are absolutely minimal, sharpness and bokeh are really convincing! I highly recommend this lens ...
