The Samyang AF 14mm f2.8 RF is a premium ultra-wide-angle prime lens engineered for Canon RF-mount full-frame mirrorless cameras. As the first third-party autofocus lens for Canon's RF system, it delivers a dramatic 113.9-degree field of view with fast, quiet autofocus performance and weather-sealed construction ideal for landscapes, architecture, astrophotography and creative wide-angle work. The compact 9.5cm design and 484g weight make it highly portable without sacrificing build quality or optical performance. Advanced optics featuring 14 elements in 10 groups (including 3 aspherical elements, 1 high-reflective element and 2 extra-low dispersion elements) with Ultra Multi-layer Coating deliver sharp, detail-rich images with minimal distortion and chromatic aberration. Internal focusing and the integrated AF/MF switch offer precise control for both photography and video, whilst the rear filter holder accepts gelatin filters for creative effects.
