Product Description

The Viltrox AF40mmf/2.5 FE is a compact, full-frame autofocus prime designed for Sony Emount cameras, offering a practical and lightweight option for everyday photography and video. With a fast f/2.5 aperture and a 40mm focal length, it provides a perspective slightly wider than a classic 50mm, making it well suited for environmental portraits, street scenes, and walkaround use. Its 10-element-in-6-group optical design includes one ED, one aspherical, and three high-refractive elements, complemented by nano multi-layer coatings that reduce flare and aberrations. Focusing is driven by a quiet STM motor for smooth performance, and the lens supports firmware updates via USB-C. Weighing just 167g and featuring weather-resistant build and a 52mm filter thread, its a versatile go-to that punches above its weight in quality and portability.
