Rokinon 14mm f/2.8 ED AS IF UMC Lens for Sony E-Mount

The Rokinon 14mm f/2.8 ED AS IF UMC Lens for Sony E-Mount is an ultra-wide-angle prime lens compatible with both full-frame and APS-C Sony E-mount mirrorless cameras, delivering a dramatic 115.7-degree angle of view on full-frame bodies (93.9 degrees on APS-C, equivalent to approximately 21mm in 35mm terms). It’s well suited to landscape, architectural, and astrophotography work where photographers want to capture sweeping, expansive scenes.

Optically, the lens is built from 14 elements in 10 groups, including two ED (Extra-low Dispersion) elements, one hybrid aspherical element, and one glass aspherical element, working together to minimize chromatic aberration, coma, and distortion, particularly in the corners where ultra-wide primes often struggle. Rokinon’s UMC (Ultra Multi-Coating) is applied across the lens elements to maintain even light transmission while reducing ghosting and flare. The bright f/2.8 maximum aperture is well suited to low-light shooting, including night photography, while also enabling shallow depth of field for selective focus.

As a fully manual lens, both focus and aperture are controlled directly on the lens barrel using an Internal Focusing (IF) system, with a soft, wide focus operation area for precise manual control. The lens has a minimum focusing distance of approximately 11 in. (28cm), and a built-in petal-type lens hood is included to help minimize flare; the lens has no front filter thread, though some listings note a rear gelatin filter slot.

Build quality centers on a robust, all-metal housing with a matte finish to reduce unwanted reflections during outdoor shoots. The lens measures approximately 3.4 in. (87mm) in maximum diameter by 3.78-4.82 in. (96-112.4mm) in length (figures vary slightly by source), and weighs approximately 485-575g depending on specific listing. It ships with a front lens cap, rear lens cap, and lens pouch, backed by a limited 1-year warranty.

As a full-frame-compatible lens, the Rokinon 14mm f/2.8 ED AS IF UMC delivers its full ultra-wide angle of view on Sony full-frame E-mount bodies while remaining compatible with Sony APS-C E-mount cameras at a narrower, 21mm-equivalent effective focal length.
