Samyang 7747 (SMY-7747, SMY/7747, SMY 7747, SMY_7747, smy-7747) Reflex 300mm f/6.3 UMC CS Lens for Canon EF
A uniquely compact telephoto option, this Reflex 300mm f/6.3 UMC CS Lens from Samyang is a mirror lens specifically designed for APS-C-format Canon EF mount DSLR cameras. Its Cassegrain design enables it to achieve a 480mm 35mm-equivalent focal length perspective within a sleek and lightweight lens design that is significantly smaller than a traditional 300mm lens.
An Ultra Multi Coating (UMC) has been applied to the eight-element-in-eight-groups lens construction, in order to minimize surface reflections and ghosting for more contrast-rich imagery. Additionally, the reflex lens design also helps to nearly eliminate chromatic aberrations for greater clarity and color accuracy around subject edges. It features a fixed f/6.3 aperture and manually focuses as closely as 3.6'.
