Nikon Nikkor 105mm f/2.5 AI Lens – Legendary Portrait Prime – Superb Optics

Description:
The Nikon Nikkor 105mm f/2.5 AI is a classic short telephoto lens, celebrated for its exceptional sharpness, creamy bokeh, and timeless rendering. This version features Nikon’s Automatic Indexing (AI) system, introduced in the late 1970s to improve metering compatibility with newer Nikon bodies.

Built on the Xenotar-type optical formula (5 elements in 4 groups), the AI version offers rich colour reproduction and flattering subject isolation—ideal for portraits, street photography, and fine art. Its reputation was cemented by Steve McCurry’s use of the 105mm to capture the iconic “Afghan Girl” image for National Geographic.

Condition:
This lens is in Excellent Condition. Optics are pristine—no haze, fungus, or scratches. Focus ring is smooth, aperture blades are snappy and oil-free. Barrel shows minimal wear. Includes front and rear caps. Note a Nikon filter is included, this needs a good clean, I have tried an initial clean but it needs time spending on it. The lens itself is fantastic.
