It is a fairly sharp lens, a bit of distortion (optical and chromatic) though. Build quality is ok. Price is pretty good.
Optical distortion (also called pin cushion or barrel distortion) will make straight lines at the edge of the frame appear curved.
Chromatic abberation will put a faint colored edge (usually purple, red or green) at edged where there is a lot of contrast. For instance, a dark car against the bright sky.
In general use this is a good lens but not for professional use.
