Nikon Nikkor AI-S 135mm f/2.8 Lens

The Nikon Nikkor AI-S 135mm f/2.8 is a manual focus prime lens built around the Nikon F mount, designed to cover a full-frame image circle. Operating at a fixed focal length of 135mm, it falls squarely in telephoto territory, making it a natural choice for shooters who want subject separation and compression at a fixed perspective. The maximum aperture of f/2.8 gives you meaningful light-gathering capability, which translates to usable shutter speeds in lower-light conditions and the ability to push background separation depending on your shooting distance.

At 430g, the lens sits in a weight class that remains manageable for extended handheld use without feeling insubstantial. Focus is entirely manual, so there are no autofocus motors or electronic communication to worry about — what you get is a straightforward, mechanical lens experience. The 52mm filter thread is a common size, meaning compatible filters are widely available and generally affordable.

With a Nikon F mount, this lens is physically compatible with a broad range of Nikon F-mount bodies, both film and digital, though adapter use on mirrorless systems will depend on the specific body and adapter combination. No image stabilization is present, so steady technique or adequate shutter speed matters.
