Nikon AF NIKKOR 50mm f/1.4 D Autofocus Lens {52}

Nikon's proven 50mm f/1.4D, the F-mount standard bearer.

The AF NIKKOR 50mm f/1.4D is one of the most straightforward lenses Nikon ever made, and that's a compliment. Seven elements in six groups, a 46-degree angle of view, and a maximum aperture of f/1.4 add up to a lens that works in light that stops most zooms cold. At 8.1 oz and just 1.7 inches long, it disappears on a camera body in a way that a fast zoom never will.

The D-type designation means this lens communicates distance information to the camera body, giving Nikon's matrix metering and flash systems more data to work with. Minimum focus sits at 1.5 ft, which gets you close enough for tight headshots or product details without a dedicated macro. The 52mm filter thread is a standard size with decades of accessory support behind it.

On full-frame bodies, this focal length renders with no distortion to speak of, making it a reliable choice when straight lines need to stay straight. At f/1.4, you're pulling in enough light to shoot by a single window or under street lamps without reaching for a flash. For the price point at which these trade hands on the used market, the optical performance-to-cost ratio is hard to argue with.

Who It's For

Nikon F-mount shooters building a first prime kit will find the f/1.4 aperture earns its keep during indoor events, concerts, and any available-light situation where a slower lens would force a compromise on ISO. Portrait photographers working full-length or environmental shots get a natural field of view that doesn't distort at close distances. Street photographers value the compact 1.7-inch profile for working discreetly. Film shooters using F-mount bodies get full mechanical aperture coupling and reliable autofocus on any body with a focus motor.

FAQ

What bodies can autofocus with this lens?

AF works on all F-mount DSLRs except the D40, D60, D3000, and D5000. On those bodies, you'll focus manually. Film SLRs with F-mount and AF capability will also work, though older mechanical bodies won't trigger autofocus.

How does the D-type designation affect metering and flash?

D-type lenses transmit distance information to the camera, which Nikon's matrix metering and i-TTL flash systems use to calculate exposure more accurately. You lose that distance data on non-D lenses, which can soften flash and metering performance in edge cases.

Is this lens truly distortion-free?

On full-frame bodies, rectilinear distortion is negligible to the point of not affecting straight lines in real-world shooting. On DX bodies, the narrower angle of view means even minor distortion becomes harder to detect.

Can you do close-up work with 1.5 ft minimum focus?

At 1.5 feet, you can frame tight headshots and product details without a macro lens, though you won't achieve true 1:1 macro magnification. For reproduction work at life-size scales, you'd want a dedicated macro lens.

Why does weight and size matter with a 50mm?

At 8.1 ounces, this lens doesn't fatigue your wrist or throw off camera balance the way a fast zoom does. It stays on the camera in situations where you'd swap a heavier lens for something lighter, which means you actually shoot it.

How much light does f/1.4 actually pull in compared to f/2.8?

f/1.4 gathers roughly 4 times the light of f/2.8, which translates to two full stops of shutter speed or ISO you can trade away. In street work or available-light portraits, that's the difference between 1/60 at ISO 1600 and 1/250 at ISO 400.

Are there autofocus speed concerns with this older design?

Autofocus will be noticeably slower than modern motors, but it's not hunting or unreliable. If you're shooting fast film speeds or video that demands snappy AF, you'll notice the lag. For stills and manual focus, it's a non-issue.
