About Rokinon

Rokinon is a brand known for manufacturing camera lenses and other optical equipment. It is part of the Samyang Optics Company, which is a South Korean optical equipment manufacturer. Rokinon lenses are often praised for their affordability and good optical quality, making them a popular choice among photographers and videographers, especially those on a budget.

We believe that this new 135mm F2.0 ED UMC lens will give you a special photographic experience. The 135m F2.0 ED UMC lens completes an optical system based on superior optical technologies, and maintains excellent resolution by adopting a high refractive low dispersive lens and an UMC (Ultra Multi Coating).

Advantages of the 135mm F2.0 ED UMC

1. 35mm full-frame image size.
2. It compensates for aberrations by using a high refractive low dispersive lens and high-class optical glass, and at the fully opened position, produces a high resolution and a high contrast at the center of the lens as well as around the periphery.
3. Allows precision focus control with smooth operation. 
4. Coating design by controlling ghosting as much as possible and reproducing vivid color images.
5. Produces smooth focusing using the aperture design, which comes due to a circular shape with its 9 diaphragm blades.
6. Easy to use for shooting animals, still life, and close shots with its shortest shooting distance of 0.8m, despite its angle of view of 18°.

The 135mm F2.0 ED UMC lens for photo shooting is designed with its mount. You can mount the lens directly onto the camera without using an additional adaptor.
