VILTROX AF 35mm F1.8 II EVO is a full-frame prime lens for Sony FE‑mount cameras. Its 35mm focal length and 63° angle of view deliver a versatile perspective for street photography, environmental portraits, travel, and everyday scenes.  Weighing approximately 355g with a 58mm filter thread, the lens balances portability and performance for all‑day use.  The F1.8 aperture performs well in low light with smooth bokeh from a 9‑blade diaphragm. APO (apochromatic) optical construction of 13 elements in 9 groups (2 ED, 2 HR, 1 UA aspherical) effectively suppresses chromatic aberration, with purple and green fringing nearly invisible. HD Nano multi‑coating reduces flare and ghosting. The STM motor delivers fast, quiet autofocus with face/eye detection. Minimum focusing distance is 0.43m (17 inches). A USB‑C port is provided for firmware updates.
