I bought it because I will use it for both my film and digital bodies. For ultra wide angles I use it with film (Nikon N-80) and for more traditional wide angle shots with my Nikon D-200. This is one of three lenses that I take with me on vacation in the mountain states. The rest are Nikkor 28-85mm and Nikkor 70-300mm with 2X Tamron SP Doubler. Not having Photoshop or anything like that yet, I wanted to be able to take very wide shots without gluing them together.
