Viltrox AF 40mm f/2.5 FE 40mm
The 40mm focal length on full-frame offers a distinctive perspective between standard 35mm and 50mm primes, and the bright f/2.5 aperture pairs with a compact, lightweight build. Its STM stepping motor delivers fast, quiet autofocus, while one ED and three HR elements control optical aberrations for crisp results. This lens suits portrait photographers and everyday Sony E-mount shooters who want an affordable prime with a unique, versatile field of view.
