Nikon NIKKOR Z 40mm f/2 (SE)

The NIKKOR Z 40mm f/2 (SE) is a compact prime for Nikon Z full-frame cameras, introduced in 2022. Its special-edition exterior has a traditional design. The moderately wide view suits street photography, travel and everyday scenes. It can show a person with some surroundings, depending on where you stand.

The single focal length is the main trade-off. You frame by stepping closer or farther rather than zooming. In return, the lens stays small and light. The f/2 aperture also gathers more light for dim rooms and evening streets. It suits anyone who wants one unobtrusive lens for daily use.

The lens weighs 6 oz (170 g) and measures 1.79 in (45.5 mm) long and 2.81 in (71.5 mm) across. Its short body takes little space in a small bag. Allow room for caps and the hood during transport. Screw-in filters must match the 52mm front thread.

On full frame, 40mm gives a moderately wide view for people, street corners and interiors. How much fits depends on your position and the scene. Moving closer makes the subject larger, but also changes perspective. Near features become larger relative to the background, so check the relationships before taking the picture.

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

Closest focus is 1 ft (29 cm), measured from the sensor, with 0.17x maximum magnification. This range can help with flowers, meals and small objects. Leave room for light ahead of the lens, and check that the camera does not shade the subject. Nine blades shape the aperture as it closes.

The body is designed to resist dust and moisture. Use cover in persistent rain and protect the open mount during lens changes. 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 your own hold. Support helps with long exposures of still scenes, but a person can continue to move.

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

The six-element, four-group design includes two aspherical elements. 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 moves elements without changing the barrel length, so the lens stays the same size as you focus.
