Nikon Nikkor 100mm f/2.8 Series E Ai-S - Nikon F Mount

The Nikon Series E 100mm f/2.8 is a compact short-telephoto prime lens originally designed as a lightweight alternative to the standard Nikkor range. Despite its 'budget' origins, it is highly regarded for its sharpness and pleasant bokeh, making it an excellent choice for portraiture and street photography. It features an Ai-S mount, allowing for aperture indexing on compatible Nikon film and digital SLR bodies. When inspecting a used Series E 100mm, check the focus ring for smooth operation, as the grease can occasionally dry out or become stiff over time. The optical construction is simple, but ensure there is no internal haze or fungal growth. SDS checks the aperture blades for oil contamination and verifies that the mounting flange shows no excessive wear or misalignment.
