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 an autofocus full-frame prime for Sony FE-mount, providing a standard 50mm perspective at f/2. STM (stepping motor) autofocus. Thirteen elements in 9 groups including ED and HR elements. Nine rounded aperture blades. 58mm filter thread. At 205g it is very lightweight. Approximately 0.51m MFD.
The optical design uses 13 elements in 9 groups (3 ED + 4 HR + 1 aspherical elements). Nine rounded aperture blades. The 58mm filter thread. At 205g the lens is very lightweight for a full-frame prime. Minimum focus distance of approximately 0.51m. STM autofocus — quiet, suited to video. f/2 maximum aperture. Full-frame coverage.
The 205g weight at 50mm f/2 positions the Viltrox AF 50mm as a lightweight standard prime alternative to heavier f/1.4 and f/1.8 options for Sony FE: at 205g it is substantially lighter than the Sony FE 50mm f/1.4 GM (~516g) and comparable to Sony's own FE 50mm f/2.5 G (~174g) with one stop wider aperture. The STM motor provides quiet, smooth focus suitable for video recording.
On the used market the Viltrox AF 50mm f/2 FE is affordable as a compact full-frame standard prime. Condition checks: STM AF response, 58mm front element for marks. Compatible with all Sony FE-mount full-frame and APS-C E-mount bodies.
