Last week I added a new lens to my collection, and at the same time traded in an old lens. The lens which I traded was the Nikkor 18-105mm for the Signa 17-50mm, the 18-105 was a good walk around lens. I got a lot of good shots with it, but I didn't think there was any point in keeping the Nikkor when Sigma covered half of its range and my 55-200 covered the rest.
Due to my hours and the distance that I travel to work, I haven't fully tested the lens. I've done a few night shots on my way home from work, and I'm very happy with the quality of the images. But one thing that is strange about the lens, well it's strange for me, and that is. To zoom in and out you have to go from left to right, while with my other lens you go from right to left.
