Rokinon Releases a 20mm f1.8 For Full Frame Cameras

Today, Rokinon announced a new 20mm f1.8 lens for photographers along with the same lens in a cinema version. It’s going to be available in pretty much every mount made, and feature seven aperture blades, a minimum focusing distance of under one meter,  and a 77mm filter thread.

More details from the just released press release are after the jump.

(New York, New York) December 27, 2016 – New and available for immediate delivery are both the Rokinon Digital Photo 20mm F1.8 and Rokinon Cine DS 20mm T1.9 Full Frame Super Wide Angle lenses.

Covering the full frame perspective of 20mm and a fast aperture design, these high value prime lenses were designed to fill the gap between the highly popular 14mm and 24mm focal lengths of Rokinon Digital Photo and Cine DS lens systems.


By virtue of a 94.8° diagonal extreme field of view, they are ideal for producing unique images and videos of landscapes, interiors, architecture, the night sky, and everyday shooting. Their bright F1.8 and T1.9 apertures allow high quality imaging in difficult lighting conditions. They can create beautiful background defocus effects with a shallow depth of field and deliver more light for easier focusing. And the 7.9in / 0.20m minimum focusing distance adds additional versatility.


The optical design of both the Digital Photo and Cine DS versions feature 13 elements in 12 groups and utilize two Aspherical and three Extra-Low Dispersion elements to minimize aberration, reduce unnecessary light dispersion, and deliver high resolution corner to corner. Ultra Multi Coating (UMC) is employed to optimize light transmission and minimize glare and ghost. The non-rotating front lens design enables the easy use of polarizing filters and the included petal type hood.


The Rokinon Digital Photo 20mm F1.8 is available in mounts to: Canon, Nikon AE, Sony E, Micro 4/3, Pentax K, and Fuji X. The Rokinon Cine DS 20mm T1.9 8 is available in mounts to: Canon, Nikon, Sony E, and Micro 4/3.
