Overview

The Samyang AF 14mm F2.8 RF (also Rokinon) is a lightweight, weather-sealed ultra-wide prime for Canon RF mount, offering a dramatic 113.9° angle of view at an affordable ~$700. Optically, it shows heavy barrel distortion (~3.8%) and high vignetting at f/2.8, typical for its class. Build quality is good with metal construction and internal focusing, but the front element prevents filter use and the lens cap feels cheap. Autofocus is quick and quiet. It suits budget-conscious landscape, architecture, and real estate photographers seeking an ultra-wide autofocus option, though its future on RF is uncertain.
