Overview

The Samyang 24mm F1.4 is a manual-focus prime known for good value and edge sharpness, but sample variation is a concern. Optical strengths include excellent coma and astigmatism control for astrophotography and strong corner sharpness stopped down. Weaknesses: soft wide open, especially at edges, with significant improvement by f/2.8. Build is solid on a metal chassis, but the focus ring could be smoother and aperture lacks intermediate stops. It suits landscape astrophotographers and those needing a fast wide-angle for tight spaces, but not for critical sharpness at f/1.4.
