Nikon 50mm f/1.8 NIKKOR AIS (Pancake) Manual Focus Lens

Nikon 50mm f/1.8 NIKKOR AI-S “Pancake” Lens
The Nikon 50mm f/1.8 AI-S (Late Version) is one of the most sought-after manual focus primes in the Nikkor lineup. Often referred to as the “Pancake” lens due to its incredibly slim profile, this version is significantly more compact than its predecessors, measuring just 1 inch in length. It is the ultimate “walk-around” lens, offering a perfect blend of portability and the legendary sharpness associated with Nikon’s 50mm optics.

Ultra-Compact “Pancake” Design
Sleek Profile: At only 1 inch deep, this late-model AI-S version is approximately 30% shorter than the earlier 1.5-inch model. It transforms any Nikon SLR or mirrorless body (via adapter) into a streamlined, pocketable setup.

Modernized Build: Unlike earlier versions, this late AI-S model features a refined, clean design without the “rabbit ear” meter claw, making it smoother to handle and store in small camera bags.

Versatile Performance: With an aperture range of f/1.8 to f/22, this lens is an exceptional choice for street photography, candid portraits, landscapes, and travel.

Optical and Mechanical Excellence
Fast f/1.8 Aperture: The bright maximum aperture provides excellent low-light capability and beautiful background separation (bokeh), making it a versatile tool for any lighting condition.

Tactile Manual Focus: Features the smooth, precise dampening that defines the Nikon AI-S series, focusing down to 2 feet (0.6m) for intimate detail shots.

Teleconverter Compatibility: For those needing extra reach, this lens can be paired with the Nikon TC-201 or TC-14A teleconverters.

Condition & Maintenance
Functional Status: This lens is in good working order. The focus ring turns smoothly, and the aperture blades are clean and responsive.

Optical Note: There is some minor internal dust present, which is common for vintage optics of this age and typically does not impact image quality or contrast.

Accessory Options: This lens is compatible with the optional HR-1 rubber screw-in hood or the HS-11 snap-on hood to further reduce flare and protect the front element.
