I had a Nikkor Zoom 24-120. After taking photos (in Yosemite) with both the Nikkor Zoom 24-120mm and the Contax 2,8/25mm, I immediately sold the Nikkor. Not even close! So I was wondering how you might think the Leica 21-35mm would compare with the Nikkor 24-120mm and the Contax 2,8/25mm? Do you think that it would be better than the Nikkor?
