Samyang MF 14mm f/2.8 RF Review

The Samyang MF 14mm f/2.8 RF is an ultra-wide manual focus prime designed for Canon's RF mount mirrorless cameras. At 14mm with a 113.9-degree angle of view, it occupies a classic focal length for landscapes, architecture, and astrophotography. Samyang has equipped the lens with a solid optical formula including three aspherical elements, two ED glass elements, and one high reflective lens across 14 elements in 10 groups, which suggests serious attention to controlling distortion and aberrations at this extreme width.

At 484 grams and 95mm long, it's reasonably compact for an ultra-wide, and the addition of weather sealing is a welcome feature at this price point. The rear filter holder system is typical for ultra-wides where front threads would be impractical. At $499, it sits in affordable territory for RF-mount glass, offering a manual focus option for shooters who prize precise control and don't need autofocus for their wide-angle work. It's a straightforward choice for Canon RF shooters seeking ultra-wide coverage without the premium price of native autofocus alternatives.
