Rokinon 10mm f/2.8 ED AS NCS CS Lens for Canon EF Mount Review

The Rokinon 10mm f/2.8 ED AS NCS CS is a manual-focus ultra-wide-angle lens designed for Canon APS-C cameras, delivering a 16mm equivalent field of view. It occupies a budget-friendly niche in the ultra-wide category, appealing to landscape, architecture, and astrophotography shooters who want dramatic perspective without the premium price tag of autofocus alternatives. The optical formula includes one extra-low dispersion element and two aspherical elements to control aberrations, plus a nano coating system to reduce flare and ghosting.

The manual-focus-only design keeps the price down but demands more from the shooter, especially in fast-paced or low-light situations where autofocus would be valuable. At f/2.8, it offers decent speed for an ultra-wide, though it won't match faster primes in challenging light. For Canon EF-mount shooters on a budget who prioritize focal length over convenience and are comfortable with manual focusing, the Rokinon 10mm presents a compelling entry into ultra-wide photography.
