Nikon AF-S NIKKOR 50mm f/1.8 G Autofocus Lens {58}

Nikon's 50mm f/1.8G: the proven standard prime for F-mount shooters.

At 185g and 2.1 inches long, this lens disappears on a camera body. The 50mm focal length sits at a 47-degree angle of view on full-frame FX bodies, close enough to natural human perspective that compositions read as honest than compressed or exaggerated. On DX crop bodies the field narrows to 31°30', making it an useful short portrait focal length without buying a second lens.

The 7-element, 6-group optical design includes one aspherical element that controls spherical aberration and coma at wide apertures, the kinds of issues that typically plague fast primes wide open. Nikon's Super Integrated Coating addresses flare and ghosting, which matters when shooting against windows, streetlights, or backlit subjects. The f/1.8 maximum aperture pulls in enough light to work at reasonable ISOs in dim interiors and gives you meaningful depth-of-field control for subject separation.

The Silent Wave Motor drives autofocus quickly and quietly, with a M/A switch that lets you grab the focus ring for manual override without flipping into a separate mode. For the price point this lens sits at, the combination of optical correction, AF performance, and build puts it well ahead of legacy 50mm options that lack internal focus motors entirely.

Who It's For

Street photographers working in mixed or low light will appreciate the f/1.8 aperture and silent AF, which won't draw attention during candid shooting. Portrait photographers on DX bodies get an effective 75mm-equivalent reach with enough subject separation at f/1.8 to isolate faces from cluttered backgrounds. Documentary and travel shooters benefit from the 185g weight and 58mm filter thread, which fits common filter systems. New F-mount shooters building a first kit will find the 50mm focal length forces compositional discipline that zoom lenses rarely teach.

FAQ

How does this 50mm perform on crop-sensor DX bodies?

On DX the 31°30' field of view gives you a short portrait length without buying a second lens. The f/1.8 aperture still delivers meaningful subject separation and low-light capability.

What does the aspherical element actually correct?

It controls spherical aberration and coma at wide apertures, the optical flaws that typically plague fast primes wide open. Shoot f/1.8 and expect sharp, clean rendering across the frame.

Can you manually focus without switching modes?

Yes. The M/A switch lets you grab the focus ring and override autofocus on the fly without flipping into a separate MF mode. Silent Wave Motor autofocus resumes when you release the ring.

Is this lens compact enough for travel?

At 185g and 2.1 inches it practically disappears on a camera body. You're carrying a premium standard prime without the bulk of heavier alternatives.

What does Super Integrated Coating do?

It suppresses flare and ghosting when shooting backlit subjects or into direct light sources. Contrast and color stay accurate in high-contrast scenes.

How close does it focus?

45 cm (1.48 feet) minimum focus distance gives you enough working room for tight portraits without buying macro gear.

Why 50mm over a kit zoom?

The f/1.8 aperture pulls in significantly more light than a kit lens and gives you genuine depth-of-field control. The fixed focal length forces intentional composition instead of lazy zooming.
