Rokinon 300mm f/6.3 overview

  • 1Description

The black Rokinon Reflex 300mm f/6.3 ED UMC CS Lens is a mirror lens designed specifically for use on Canon EF-M mount mirrorless cameras. The lens' Cassegrain design enables it to achieve a 480mm 35mm-equivalent focal length perspective within a compact and lightweight lens design that is significantly smaller than a traditional 300mm lens. It features a fixed f/6.3 aperture and utilizes manual focus operation for focusing as closely as 2.95'.

One extra-low dispersion element and the inherent mirror construction of the lens work to eliminate chromatic aberrations while providing notable image sharpness and clarity. Furthermore, the UMC (Ultra Multi Coated) coating has been applied to reduce surface reflections, lens flare, and ghosting while also contributing to improved overall contrast.

Mirror lens designed specifically for Canon EF-M mount mirrorless cameras.
Catadioptric system with Cassegrain design helps to reduce the overall size of the lens while still providing a 35mm-equivalent focal length of 480mm.
One extra-low dispersion element and a UMC coating are integrated into the lens construction to improve sharpness and clarity as well as enhance the overall image contrast.

    Rokinon 300mm f/6.3 reviews

    Reflex 300mm f/6.3 ED UMC CS Lens for Canon EF-M Mount (Black) is rated 3.0 out of 5 by 1.
    Rated 3 out of 5 by from Fun but tricky Having failed to read the PDF manual, I failed to see the significance of the C.Fn IV/7 . In order for this lens to function this must be enabled. Actually, even the manual may not make this clear. Failing a Canon lens, this is an OK shortstop. Handheld is iffy as the bounce in even calm hands is considerable. The magnified live view is helpful but exacerbates the appearance of shake. Manual focus is automatically set. The single aperture is odd as well. Basically this is a fun toy that is likely to remain so.
