Viltrox AF 40mm F2.5 40mm
The f/2.5 aperture and STM motor deliver quiet autofocus and soft bokeh, supported by a 6-group,10-element optical formula for sharp imaging. A hardened aluminum mount and water- and smudge-repellent front coating lend weather-resistant handling, while the 0.34m minimum focus distance adds close-up versatility. It suits Nikon Z shooters who prioritize a walk-around 40mm prime for portraits and day-to-day shooting over an ultra-light travel lens.
