Samyang AF 14mm f/2.8 FE - Sony E-mount

The Samyang AF 14mm f/2.8 FE is an ultra-wide-angle autofocus lens for Sony full-frame mirrorless systems. It provides a 113.9-degree angle of view, making it a popular choice for astrophotography, interiors, and landscapes. The optical design includes three aspherical and two low-dispersion elements to minimise distortion, which is common in such wide focal lengths. It features a built-in petal-shaped lens hood and a rear filter holder, as the bulbous front element precludes the use of standard screw-in filters. Used 14mm lenses require careful inspection of the prominent front element for scratches, as it cannot be protected by a standard UV filter. SDS checks the autofocus motor for smooth operation and ensures the lens communicates correctly with the camera body for in-camera corrections. The fixed hood should be checked for cracks or impact damage. Given the wide angle, optical centring is vital; SDS verifies that sharpness is uniform across the frame to rule out internal alignment issues.
