Rokinon 10mm F/2.8 ED AS NCS CS (Manual Focus) Lens For Canon Mirrorless EF-M Mount Review

The Rokinon 10mm f/2.8 ED AS NCS CS is a compact ultra-wide manual focus lens designed for Canon's EF-M mirrorless mount. With a 10mm focal length on APS-C sensors (equivalent to roughly 16mm full-frame), it offers dramatic perspective for landscapes, interiors, and creative shooting. The f/2.8 aperture is reasonably bright for a wide prime at this price point, and the ED glass elements aim to control chromatic aberration.

This is a manual-focus-only lens, which suits deliberate shooting styles but requires patience and practice, especially at wide apertures. Rokinon's budget optics typically sacrifice autofocus and electronic communication for affordability, making them a practical choice for hobbyists and creators who don't mind manual control. At 173 dollars MSRP, it sits in the entry tier for ultra-wides, and the used bargain condition listing suggests an even lower entry cost. Build quality and edge sharpness are typically acceptable but not exceptional in this segment.
