Overview

The Samyang 21mm F1.4 is a compact, manual-focus lens for APS-C mirrorless cameras, offering a fast aperture and good value. Optically, it delivers strong sharpness and contrast from f/1.4, but chromatic aberrations are a notable weakness, partly due to lacking electronic contacts for in-camera correction. Build quality is decent with a mix of metal and plastic, though not weather-sealed. The focus ring is smooth but can be accidentally turned, and the aperture ring is small. It suits photographers comfortable with manual focus who prioritize optical performance and compactness over autofocus and robust build.
