Nikon Nikkor-M 300mm f/9 lens in excellent condition. This is a compact large format lens with an image circle sufficient for 8x10" film. A classic Tessar design, this lens boasts impressive resolution and possibility for movements on 4x5". Mounted in a Copal 1 shutter, healthy throughout its range of speeds. Aperture is smooth and glass is free of issues. Good cosmetic condition with slight damage to the filter ring—a filter will mount alright but it is a bit stiff in places. Includes a #1 retaining flange.
