I have a D90 with the kit lens AF S DX VR 18-200. So far, I was also very pleased with this all-around lens. However, I am now on holiday to USA (New York) and drove in to take pictures of the street canyons and the landscape in the area well, I've been looking for a wide-angle. Here I found the Sigma lens. First time for processing. The lens has a very good feel and is very well made. The only difference from my Nikon lens: the approach we zoom in Nikon made with the front adjustment, whereas this is done in Sigma to the rear adjustment. Otherwise the objective of the use and the settings is very similar to that of Nikon. Autofocus using HSM works very well. The light intensity (F 3.8) still allows a good result even with diffuse light conditions. The lens works perfectly with the Nikon D90. The supplied pouch protects the lens and with press and I have also brought my purely 18-200 lens, so I had to take only one lens case. The bag also has a strap for hanging on a belt, also very practical. In practice, I have the lens for photos of houses in the narrow street battles of New York used to be able to still take pictures at close range, the entire building can. In addition, it was even when shooting on the entire skyline of great help, simply because a better picture of the landscape can be shown. I can due to its build quality and image Results only recommend this lens.
