Viltrox AF 40mm F/2.5 Lens
The Viltrox AF 40 mm f/2.5 FE is a compact, full-frame prime lens designed for Sony E‑mount mirrorless cameras. Despite its small size, it features a fairly bright f/2.5 maximum aperture that makes it suited for general-purpose use — street photography, travel, portraits, and everyday shooting.
Its optical formula includes 10 elements in 6 groups, with one ED (extra‑low dispersion) element, three HR (high‑refractive) elements, and one aspherical element — designed to deliver sharpness and control aberrations while keeping the lens lightweight. Autofocus is handled by a quiet STM (stepper) motor, making it suitable for both still photography and video. The lens uses internal focusing, so its physical length doesn’t change when focusing.
Its minimum focus distance is 0.34 m (34 cm), giving a maximum magnification of ~0.14×. The 7‑blade diaphragm helps deliver pleasant out-of-focus rendering. On the physical side, the lens is very light — around 167 g according to Viltrox’s site. The front filter thread is 52 mm, making it compatible with commonly available filters.
