The 120mm Nikkor-SW is a member of the SW series, which feature wide coverage power and large image circles for their focal lengths. Covering power can be extended to a whopping 105°/106° by stopping the lens down to f/22. All of the SW series lenses deliver high contrast and resolution, reduced flare and excellent color rendition, thanks to Nikon's Integrated Coating and strict control of aberrations.
The 120mm f/8.0 SW is a great moderately wide angle lens for 4x5 use, with an extreme amount of shift available to cameras that can deliver it. It also makes for a classic wide angle lens for 5x7 cameras.
