When I was traveling with the D7000, I had briefly the UWW Lens Sigma 10-20mm 4-5.6 in use, but I was with the lens never really warm, because it was how I had predicted: The extreme wide angle is optically not just a finger exercise for lens manufacturers. What clouded the joy were chromatic aberration, distortion and strong distortion. I stayed away after a while the UWW-range. Only after purchasing the D600 germinated in me again the desire to take pictures with such lens landscapes. I Belas and tried many things out. I toyed with the idea, one or two prime lenses to buy, but this rejected due to lack of quality and versatility. It ultimately remained only the Nikkor 14-24mm 2.8G Nikkor 16-35mm and 4G in the race. For the 14-24mm its enormous sharpness spoke already at full aperture that also an unusual exemption offered potential, but was the 16-35mm versatile filter friendly, smaller, lighter and cheaper UNMD by the VR even in low light a Garrant for sharp images, so it was awarded the contract. After I experimented a lot and was able to complete a broader deployment in Turkey, I can only say: Breathtaking! No CAs, distortion and distortion are hardly worth mentioning and resolved quickly in Lightroom in 16 / 35mm, the sharpness, the colors and contrasts are phenomenal for landscape photography and the lens covers wide angle basically from incomparably thorough. The VR allowed me to produce at up to a quarter of a second from the hand-sharp images and the processing and handling of speaking just for himself. On top of that the lens is sealed against dust and moisture and filter capable, so she could finish the search for the best possible solution to Wide grandiose way for me. Strong buy recommendation, the 16-35mm 4G will give you many, many years a faithful companion be.
