The Nikon Nikkor M 300mm f/9 is a compact large format lens with a 325mm image circle and 57-degree coverage, covering 8x10in with limited movements. At just 290g with a 52mm filter thread, the M series prioritises compactness and light weight. It is an extraordinarily lightweight 300mm option, popular among hikers and backpackers who photograph with 4x5in or 8x10in. The minimum aperture of f/128 provides extreme depth of field when needed.
