Description — Nikon 105mm f/2.5
The Nikon Nikkor AI-S 105mm f/2.5 is a prime telephoto lens built for the Nikon F mount, with full frame coverage and a maximum aperture of f/2.5. Operating at a fixed 105mm focal length, it falls into the telephoto range and is a deliberate, single-purpose optical tool. Focus is manual only, putting full control in the photographer's hands.
The lens weighs 435 grams and accepts 52mm screw-in filters, keeping it practical for everyday use. There is no image stabilization, consistent with its manual, traditional character. Designed for full frame coverage, it works without compromise on full frame Nikon bodies using the long-established Nikon F mount.
For photographers who prefer working with manual glass and a fixed perspective, this 105mm prime offers a straightforward, no-distraction shooting experience.
