With the ultra-wide view of a 20mm lens, you're free to capture expansive landscapes and architecture, wedding parties, an entire band on stage, crowd shots and much more. Add low-light capabilities to that view, and the shooting possibilities are nearly endless.

Fixed-focal-length lenses seem to be flavour of the month right now, particularly with photographers looking for the best-quality optics to match the latest generation of high-resolution sensors. As such, the AF-S Nikkor 20mm f/1.8G ED should prove to be extremely popular.

The Nikon 20mm ƒ/2.8 AF-D has been waiting 20 years for a refresh; it's nice to see Nikon completing its prime lineup in the ƒ/1.8 configuration. The lens isn't exorbitantly expensive, and performs extremely well.
