Nikon AF NIKKOR 50mm f/1.4D Lens

Nikon AF NIKKOR 50mm f/1.4D Lens
Classic Compact Normal Prime – Ultra-Bright f/1.4 Aperture, Super Integrated Coating & Tactile Aperture Ring
The Nikon AF NIKKOR 50mm f/1.4D is a time-tested, high-performance normal-length prime lens engineered for full-frame FX-format Nikon F-mount DSLRs (and DX-format crop models, where it provides a short-telephoto 75mm equivalent portrait perspective). Renowned for its compact profile and razor-sharp rendering, this versatile lens closely mirrors the natural field of view of the human eye. It is an enduring favorite for low-light street photography, environmental portraits, travel documentation, and everyday snapshots.

The hallmark of this D-type prime is its ultra-bright f/1.4 maximum aperture. This fast opening acts as a massive light funnel, letting creators maintain fast handheld shutter speeds in dimly lit ambient environments while granting deep, selective control over shallow depth of field. Built with an independent, physical manual aperture selection ring, an anti-reflective Super Integrated Coating to maximize frame contrast, and a mechanical screw-drive autofocus coupling, this legendary pocketable prime brings reliable professional utility to compatible Nikon bodies.

Key Features & Optical Performance
Natural Normal-Length Perspective: Formulated natively for full-frame FX-format Nikon F-mount cameras to deliver a standard 50mm view. It doubles as an excellent portrait lens on DX-format camera bodies, yielding a 75mm equivalent focal length.

Ultra-Fast f/1.4 Low-Light Aperture: Provides exceptional light-gathering capabilities to pull clean exposures from available ambient light, while enabling dramatic subject isolation with a razor-thin depth-of-field window.

Super Integrated Coating (SIC): Applied to individual internal elements to minimize surface reflections, lens flare, and ghosting artifacts, maintaining rich image contrast and strict color accuracy when framing near intense light sources.

Mechanical D-Type Autofocus Coupling: Driven by the camera body’s built-in AF motor to deliver quick, precise focus locks. This traditional mechanical link also passes precise subject-to-camera distance data to the body for optimized matrix metering calculations.

Tactile Manual Aperture Selection Ring: Features an independent physical aperture ring on the lens barrel, allowing for seamless manual exposure management on older film bodies or quick parameter tracking.

Rounded 7-Blade Diaphragm Iris: Incorporates a seven-blade circular aperture mechanism to produce a smooth, soft out-of-focus background quality and circular bokeh highlights when operating at wide openings.

Mechanical Autofocus Compatibility Warning
Important Compatibility Note: This lens relies on a traditional mechanical mechanical screw-drive system and does not contain an internal focus motor.

Full Autofocus Support: Autofocus is fully operational only when mounted on select pro-sumer and professional Nikon DSLRs equipped with a built-in AF motor (e.g., Nikon D7000-series, D90, D200, D300-series, D500, D600-series, D700, D750, D780, D800-series, D3, D4, D5, D6, etc.).

Manual Focus Only: Autofocus is not supported when used on entry-level DSLRs that lack an internal drive motor, such as the D3000-series, D5000-series, D40, D40X, and D60. On these camera bodies, the lens will function in Manual Focus only.
