Nikon Micro-Nikkor 105mm f/2.8 Ai-S - Nikon F Mount

The Micro-Nikkor 105mm f/2.8 Ai-S is a manual focus macro lens providing a 1:2 reproduction ratio, which can be extended to 1:1 with the PN-11 extension tube. It is prized for its exceptional sharpness and flat field of focus, making it a reliable tool for copy work and detailed product photography. The all-metal construction and long focus throw allow for precise manual adjustments. Used units are checked for the 'creeping' of the focus barrel, as the heavy optical cell can sometimes cause the lens to extend under its own weight if the damping has worn. SDS inspects the aperture blades for oil—a common issue on older manual Nikkors—and ensures the glass is free from the 'balsam separation' sometimes found in older telephoto designs.
