Nikon NIKKOR Z 40mm F/2

The NIKKOR Z 40mm f/2 is a compact prime introduced in 2021 for Nikon Z full-frame cameras. Its moderately wide view suits street photography, travel and everyday scenes. A person can appear with their surroundings, depending on where you stand. The short barrel takes little space in a small kit.

The main choice is whether one focal length fits the way you work. There is no zoom to change framing from a fixed position. Before an event, check whether the view covers your planned subjects and the available space. Walls, tables and barriers can limit movement.

The lens weighs 6 oz (170 g) and measures 1.79 in (45.5 mm) long and 2.76 in (70 mm) across. These dimensions describe the standard version. Allow space for caps and the hood when packing it beside a camera body.

A screw-in filter attaches directly to the 52mm thread, so any polariser or ND filter must match that size. The physical specification scores 64/100.

On full frame, 40mm gives a moderately wide view for people, streets and interiors. Moving closer makes the subject larger, but also changes perspective. Near features become larger relative to the background. Choose position for those relationships, then check the borders for distractions.

The f/2 maximum aperture admits more light than a smaller opening. At a given shutter speed, it can allow a lower ISO in dim restaurants or evening streets. A close subject can have a soft background when there is enough space behind it. Stop down when more depth of field is needed.

Closest focus is 1 ft (29 cm), measured from the sensor, and maximum magnification is 0.17x. This range can help with meals, flowers and objects on a table. The minimum distance is not the clearance in front of the glass. Leave room for light and check that the camera does not shade the subject.

The body is designed to resist dust and moisture. Use cover in persistent rain and protect the open mount when changing lenses. Dry the exterior before storage after working in damp surroundings.

There is no image stabilisation in the lens. A camera with body stabilisation can help with shake. Choose a shutter speed for subject movement as well as the steadiness of your hold. Firm support helps with long exposures of still scenes.

Remove loose particles before wiping the front glass. Check for marks when photographing towards a bright lamp or window. Keep both ends capped during transport.

Two aspherical elements are included in the six-element, four-group design. Their shaped surfaces help correct distortion and spherical aberration. Distortion can make straight doorframes or building edges appear curved. These design features do not establish measured image quality on their own.

Internal focusing keeps the external length unchanged as focus adjusts. Check focus again when the subject or camera moves, particularly at close distances with a wide aperture.
