Compact Prime for Nikon F-Mount

The AF NIKKOR 50mm f/1.8D is a fixed focal-length lens built for Nikon F-mount cameras. It covers both FX and DX formats as well as 35mm film bodies. The fast f/1.8 maximum aperture suits portrait, travel and general photography where shallow depth of field and low-light capability are priorities.

Aperture Ring and Autofocus Limits

The lens offers a maximum aperture of f/1.8 and stops down to f/22 with a seven-blade diaphragm. An aperture ring provides manual control during Live View or video work. Autofocus relies on a camera body with a built-in focus motor; bodies without that motor will only support manual focus.

Lightweight Build and Filter Thread

Weighing approximately 155g, the lens uses a 52mm screw-on filter thread and measures 50mm in focal length. Its six-element, five-group construction includes Super Integrated Coating to reduce flare. The compact barrel and D-type distance encoding make it a practical everyday carry for compatible Nikon SLR and DSLR systems.

Questions about this item

Should I pick this 50mm f/1.8D or look for a different focal length?

The 50mm focal length matches the classic normal perspective on FX and 35mm film, while on DX it gives a 31.30-degree angle of view equivalent to a short telephoto.

How does the f/1.8 maximum aperture behave on an actual camera?

At f/1.8 the lens gathers ample light for dusk, dawn and dim interiors without flash, and the seven-blade diaphragm produces smooth background blur at close range.

What does the Nikon F mount limit in everyday use?

The F mount works on FX, DX and 35mm film bodies, but autofocus requires a camera with a built-in focus motor; on bodies without that motor you must focus manually.
