Nikon 135mm f/3.5 NIKKOR AI Manual Focus Lens Review

The Nikon 135mm f/3.5 NIKKOR AI is a legacy manual focus telephoto lens from Nikon's pre-autofocus era. Introduced in the late 1970s, it was designed for Nikon's AI (Aperture Indexing) mount cameras and can be adapted to modern Nikon DSLRs and mirrorless bodies with varying degrees of functionality. At 135mm, it offers a moderate telephoto field of view useful for portraits, detail work, and selective framing. The f/3.5 maximum aperture is modest by today's standards but typical for compact telephoto primes of its generation.

This particular copy is sold as a bargain-grade used unit, meaning visible cosmetic wear and possible optical imperfections. At $58, it's priced for budget-conscious shooters experimenting with vintage glass or seeking an affordable entry into manual focus telephoto shooting. Build quality is all-metal, and the lens is compact and relatively light. Image quality varies by copy condition, but clean examples can deliver sharp results stopped down, though wide-open performance is usually softer and contrast lower than modern optics. It lacks coatings and correction technologies found in contemporary lenses, so expect flare and chromatic aberration in challenging light.
