Sony FE 50mm f/1.8 Lens
Compact Full-Frame Normal Prime for Sony E-Mount – Bright f/1.8 Maximum Aperture, Classic Double-Gauss Optical Design with Aspherical Element, DC Actuator Autofocus Motor, Circular 7-Blade Diaphragm, Durable Metal Bayonet Mount, Lightweight Walk-Around Profile, Includes Front & Rear Lens Caps (Excellent Condition)

The Sony FE 50mm f/1.8 is an essential, ultra-lightweight normal-length prime lens engineered for full-frame Sony E-mount mirrorless cameras (also fully compatible with APS-C bodies, providing a 75mm equivalent short-telephoto field of view). Serving as a classic, versatile standard prime for portraiture, street photography, documentary stills, low-light indoor shooting, and everyday walk-around capture, it balances optical performance with an exceptionally compact, portable footprint.

The optical construction features 6 elements in 5 groups arranged in a proven double-gauss configuration, incorporating one precision aspherical element to correct spherical aberrations, astigmatism, coma, and field curvature for sharp, consistent edge-to-edge imaging. Its fast f/1.8 maximum aperture excels in dim ambient light and offers selective focus control with shallow depth of field, complemented by a rounded 7-blade circular diaphragm for smooth background bokeh. Autofocus is driven by a responsive DC actuator motor designed for quiet, accurate focusing in both photo and video applications. The lens is built with a solid metal bayonet mount, a tactile ribbed manual focusing ring, and a standard 49mm front filter thread.
