Viltrox's compact full-frame 50mm f/2 for Sony FE — tiny, affordable, and sharp for everyday shooting.
The Viltrox AF 50mm f/2 is a compact autofocus standard prime for Sony full-frame E-mount. It provides a standard perspective at f/2 in an incredibly compact and lightweight package, targeting everyday shooters who want a small walk-around lens.
Optically good — sharp from f/2.8 with acceptable performance at f/2. Stepping motor AF is quiet and adequately fast. Eye-detect AF works with compatible Sony bodies. The f/2 aperture provides decent subject separation and low-light capability.
Sony FE mount with 52mm filter thread. Approximately 175g — near-pancake. No weather sealing. Minimum focus distance 45cm. USB-C port for firmware updates. 9 rounded aperture blades. Full-frame coverage. Plastic barrel with metal mount.
Available used very cheaply. The Sony FE 50mm f/1.8 and Samyang AF 45mm f/1.8 are alternatives. Viltrox's value proposition is the compact size and low price. Check for firmware updates. An excellent budget everyday lens for Sony full-frame shooters.
