Super Wide-Angle Prime. The Rokinon SP 10mm f/3.5 provides a 130° angle of view on full-frame Canon EF-mount cameras and a 104° angle of view on APS-C cameras, where it’ll also give you a 16mm equivalent focal length. It’s great for interior, landscape, and architectural photography.

Advanced Optics. The eleven-group/eighteen-element optical formula incorporates three aspherical elements, three extra-low dispersion elements, and one high-refractive index element to help prevent color fringing, distortions, and aberrations, all while retaining sharpness, clarity, and color accuracy at any aperture or focus distance. The Ultra Multi-Coating and built-in hood control ghosting and flare, even when working in bright, direct light.

Manual Focus. The manual-focus design allows for precision adjustments, and lets you work with subjects as close as eleven inches away.

High-Quality Build. This lens’s aluminum-alloy construction is both lightweight and tough, meaning that you can work under adverse conditions without worry. The built-in petal-shaped hood helps protect the lens from unwanted light.
