Samyang af 14mm f 2 8 vs sony fe 14mm f 1 8 gm?

The Sony FE 14mm f/1.8 GM is the brighter lens. At f/1.8 it gathers about a stop and a half more light than the Samyang's f/2.8, which matters for night skies, interiors and anything handheld in dim light. On APS-C it also gives more background blur, about what f/2.7 gives on full frame.

The Samyang AF 14mm f/2.8 is the choice if you shoot Canon RF, because it's the only one of the two that fits that mount. It also fits Sony E. Its f/2.8 is plenty for landscapes and architecture, where you usually stop down anyway. The focal length converter explains how aperture and sensor size change depth of field.

Neither lens is stabilised, so for static subjects you'll rely on shutter speed.
