The Samyang 14mm F2.8 for Sony E-mount is an ultra-wide-angle manual-focus lens designed for full-frame mirrorless cameras. It is commonly used for landscape, architecture, interior, and astrophotography due to its extremely wide field of view and bright f/2.8 aperture, which performs well in low-light and night sky conditions. The lens delivers good center sharpness, solid contrast, and controlled distortion for its focal class, especially when stopped down slightly. As a fully manual lens, it requires manual focusing and exposure control, but it is appreciated for its lightweight design and affordable access to an ultra-wide perspective on Sony E-mount systems.
