(Refurbished Excellent) Rokinon 10mm f/2.8 ED AS NCS CS - E-mount Camera Lens

The Rokinon 10 mm f/2.8 ED AS NCS CS (Sony E-mount) is a specialized ultra-wide-angle prime lens designed for APS-C format mirrorless cameras, providing a dramatic 109.5° angle of view ideal for landscape, architecture, interiors, astrophotography, and creative wide shots. It offers an effective focal length of roughly 15 mm on APS-C sensors, giving you expansive perspectives that are hard to achieve with standard lenses.

Optical Performance & Build

Wide f/2.8 aperture: A bright max aperture that helps in low-light conditions and offers more control over depth of field.

ED & aspherical elements: One extra-low dispersion (ED) and two aspherical elements (AS) minimize chromatic aberrations and distortion, producing sharp, clear images.

Nano Coating System (NCS): Reduces flare and ghosting for improved contrast and color fidelity, especially in backlit scenes.

Manual focus: Precision focus control by hand lets you dial in exact focus — ideal for landscapes, architecture, and video projects.

Who It’s For

This lens is best if you want expansive ultra-wide views and creative low-light capability on an APS-C Sony E-mount body (like Sony α6000/α5000 series). Since it’s fully manual focus and aperture control, it fits photographers and videographers who enjoy hands-on shooting and compositions where autofocus isn’t critical.
