The Viltrox AF 40mm f/2.5 is a fixed focal length lens with autofocus and Full Frame coverage. Its 40 mm focal length is suitable for street, still-life, and portrait photography. The f/2.5 aperture helps blur the background and produce clear images in low-light conditions.
The built-in STM stepping motor supports autofocus and focus tracking, as well as eye and face autofocus. The internal optical construction comprises 10 elements in 6 groups, including one ED lens, three high-refractive-index lenses, and one aspherical lens. A multilayer nano coating and a water-repellent, anti-smudge coating on the front lens complete its design.
