The Nikkor 28mm f/3.5 AI lens provides a field of view of 42 mm on a Nikon DX SLR. All the characteristics of a wide angle lens, such as plenty of depth-of-field, are nevertheless preserved. The f/3.5 maximum aperture is a bit slow but on the plus side performance is good even wide open and impressive when stopped down. The advantage of using it on a crop sensor is that you are experiencing only the centre performance and not much of the fuzzy edges. It's interesting and fun to use a lens which for all practical purposes behaves like something between 35mm and 50mm lenses on a full frame camera.
