Samyang's compact AF 45mm f/1.8 for Sony FE — lightweight full-frame standard prime at budget price.
The Samyang AF 45mm f/1.8 FE is a compact autofocus standard prime for Sony full-frame E-mount, providing a slightly wider-than-50mm perspective. It offers full-frame coverage at f/1.8 in a remarkably small and affordable package.
Optically good — sharp from f/2.8 with acceptable performance at f/1.8. The 45mm focal length provides a natural, slightly wider perspective than 50mm. Stepping motor AF is quiet and adequately fast. Well-suited to both stills and video.
Sony FE mount with 49mm filter thread. Weighs just 162g — near-pancake. Full-frame coverage. No weather sealing. Minimum focus distance 45cm. 8 aperture blades. Also sold as Rokinon AF 45mm f/1.8.
Available used very cheaply — outstanding value. The Sony FE 50mm f/1.8 is the obvious competitor. The 45mm focal length may suit some shooters better than 50mm. Check for AF accuracy — some copies show inconsistency. A budget full-frame everyday lens for Sony.
