Summary

The NIKKOR Z 40mm f/2 from Nikon is an ultra-compact, lightweight prime lens designed for Z-mount full-frame and DX-format mirrorless cameras. Bridging the gap between the classic 35mm wide-angle and 50mm standard focal lengths, its 40mm perspective delivers a natural, candid view closely matching human sight. This versatile focal length makes it an ideal walkaround companion for street photography, environmental portraits, travel documentation, spontaneous snapshots, and dynamic video blogging where unobtrusive gear is essential.

Boasting a bright f/2 maximum aperture, the lens excels in available-light situations while granting refined control over depth of field for pleasant subject separation. Its 9-blade rounded electromagnetic diaphragm produces smooth, pleasing out-of-focus highlights and creamy background bokeh. Optically, it employs 6 elements arranged in 4 groups, featuring two aspherical elements to effectively suppress spherical aberrations, field curvature, and coma, yielding impressive sharpness, contrast, and color fidelity across the entire frame.

Autofocus is driven by a swift and whisper-quiet stepping motor (STM) with an internal focusing (IF) mechanism, ensuring that the overall barrel length remains constant during operation. Video shooters will appreciate the suppression of focus breathing and smooth exposure transitions. A customizable control ring allows tactile adjustments for manual focus, aperture, exposure compensation, or ISO directly from the lens barrel. Weighing a mere 170 grams (6.0 oz) and engineered with dust and drip resistance, it is a quintessential grab-and-go prime for creators on the move.
