Slightly wider than the standard 50mm, this 40mm f/2.8 lens is designed for FX-format Nikon F-mount DSLRs, however can also be used with DX models where it provides a 60mm equivalent focal length.

Pancake form factor is slim and lightweight to make for an especially portable lens to suit everyday shooting.

Relatively bright f/2.8 maximum aperture affords control over depth of field and also helps to realize the compact overall size.

One aspherical element is located at the rear of the lens construction, and helps to minimize spherical aberrations and distortion for greater sharpness and clarity.

Individual glass elements are multi-coated to resist flare and ghosting for improved contrast and color fidelity.

A DC motor is used for quick and accurate autofocus performance, and a dedicated switch lets you quickly change from AF to MF control. A focus distance scale is also featured to aid with pre-focusing techniques.

Chrome-plated metal lens mount is durable and accurate for a secure fit with the camera body and gold-plated contacts help to ensure consistent communication between the lens and camera.

Six-blade diaphragm contributes to a smooth bokeh quality.

A micro-USB port is located on the front of the lens to allow for updating the lens's firmware.
