Rokinon 300mm f/6.3 overview

  • 1Description

The Rokinon Reflex 300mm f/6.3 UMC CS Lens is a mirror lens designed specifically for use on DX-format Nikon F-mount DSLR cameras. The lens' Cassegrain design enables it to achieve a 450mm 35mm-equivalent focal length perspective within a compact and lightweight form factor 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 3.6'.

The mirror construction of the lens inherently works to reduce chromatic aberrations and a 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 DX-format Nikon F-mount DSLR cameras.
Catadioptric system with Cassegrain design helps to reduce the overall size of the lens while still providing a 35mm-equivalent focal length of 450mm.
A UMC coating has been applied to the lens elements to improve clarity, minimize reflections, and enhance overall image contrast.

    Rokinon 300mm f/6.3 reviews

    Reflex 300mm f/6.3 UMC CS Lens for Nikon F is rated 3.8 out of 5 by 4.
    Rated 3 out of 5 by from Nice, but Not for Me. The construction and manual focus operation of this little lens was very good (despite being all plastic, it operates well). However, I have returned the lens to B&H. After trying it out, I found that my ability to focus this lens on my Nikon D7100 was poor. I don't think this is a factor of this lens simply these current auto focus cameras lack the capacity to accurately manual focus a lens. There is no split screen focus aid that was present on manual focus cameras of the 1970s that I was familiar with. Some people do successfully use manual focus lenses on modern DSLRs, but I will not be doing this.

    Rated 4 out of 5 by from I would buy this product again Used for flower and wildlife photography. With Vivitar 2x converter, pictures are acceptably sharp though focusing must be precise. I have an old Nikon D70s. Lens and converter work fine with this camera.

    Rated 4 out of 5 by from Catadioptric lens for Nikon F mount Excellent lens, but very difficult to focus in the range near infinity which is my intention for using it. astro
