I bought this lens after shooting a typhoon day with A09 because it's fast and cheap, which made it the first prime of mine. This is among the sharpest of Nikon, the image quality made me switch to prime... Put aside the cheap construction of this lens (the focus ring is uneven with my copy), the cons of this lens lies in its bokeh and its rather cold color rendition. The light spot in the background is far from circle due to its non-circular aperture, and it's not nice. This lens weighs only 155g.
