Nikon Z 40mm f/2

£249/$297 A compact but very capable prime

Filling a gap between Nikon’s f/1.8 S-line 35mm and 50mm Z-mount lenses, the Z 40mm f/2 has a fittingly compact and lightweight build. The design is simple, based on six optical elements arranged in four groups, with no ED (Extra-low Dispersion) glass. There’s no auto/manual focus switch, no optical VR and a genuine Nikon lens hood isn’t available.

That may sound disappointing but the lens functions well as a compact standard prime, with a useful focal length for street shooting on a fullframe camera and a longer 60mm effective length on a DX body. Handling is refined with an electronically coupled, customizable MF ring, and the stepping motor-based AF system is nippy for stills along with smooth, near silent focus transitions for video.

Performance

As with its sibling Z 28mm f/2.8 lens, also on test, the 40mm punches above its weight in terms of performance. Sharpness is impressive while bokeh is smooth and remains good when stopping down a little, helped by a well-rounded nine-blade diaphragm.

N-photo verdict

This lens is compact and lightweight yet delivers excellent image quality at a bargain price.
