Samyang 10mm f/2.8 ED AS NCS CS Review

The Samyang 10mm f/2.8 ED AS NCS CS is an ultra-wide manual focus lens designed for APS-C and Micro Four Thirds mirrorless cameras. At 10mm, it delivers a dramatically expansive field of view well suited to landscape, architecture, and interior work, and the fast f/2.8 aperture provides flexibility in lower light compared to many kit zooms. The ED (Extra-low Dispersion) glass and aspherical elements aim to control aberrations across the frame, while the NCS (Nano Coating System) helps reduce flare and ghosting.

Priced around $330, the lens occupies the budget end of the ultra-wide prime segment, appealing to enthusiasts who want wide-angle reach without the cost of first-party options. Manual focus only means it's best suited to deliberate, stationary subjects rather than fast-moving scenes. Build quality and optical performance at this price point typically favor sharpness in the center over edge-to-edge consistency, and vignetting and distortion are common trade-offs in ultra-wide designs. It's a straightforward choice for creators prioritizing angle of view and aperture over autofocus convenience.
