The Nikon Nikkor M 200mm f/8 is a compact large format lens with a 210mm image circle and 55-degree coverage. At just 180g with a 52mm filter thread, the M designation indicates a compact design optimised for minimal weight. It covers 4x5in with some movements and is one of the lightest lenses at this focal length. The slower f/8 aperture is the trade-off for its remarkably small size, making it ideal for backpacking.
