I bought this lens to use on my D700 after reading various internet testing. His most: excellent dive, good control of chromatic aberrations and surprisingly good build quality for this price. The objective is relatively heavy and gives a solid feel. In addition, it is significantly more compact than the 14-24 and can easily be carried away on a trip. The absence of AF can be compensated by the Exposed Pad on the viewfinder or using the LiveView mode. His only weakness: his mustache distortion is visible if horizontal or vertical lines in the frame. Fortunately, it is very well corrected PTlens (whose license costs only $ 25). In conclusion, an excellent deal.
