You may recall, Rokinon/Samyang announced their new super wide-angle full-frame 20mm T1.9 Cine DS prime and 20mm f/1.8 stills version back in the Summer, and now they are shipping worldwide. The 20mm focal length sits in between the highly popular 14mm T3.1 ultra-wide (which for some, including me, is way too wide when used on a Sony A7sII for example; plus on the 14mm you can’t use screw-on filters because its so damn wide and the petal shaped hood isn’t threaded) and the 24mm T1.5 Cine DS lens.
The new Rokinon 20mm T1.9 Cine DS super-wide angle lens is priced at $799 at B&H and in stock. The 20mm T1.9 is available in Canon EF, Sony E, Micro Four Thirds, and Nikon F mounts. In Europe, Rokinon lenses are sold under the Samyang and Walimex names, but nonetheless are the exact same lenses.
The lens features a 94.8° diagonal extreme eld of view making it ideal for a variety of situations including both stills images and videos of landscapes, interiors, architecture, documentary and low-budget narrative productions.
The fast T1.9 maximum aperture is a huge bonus making shooting in low-light environments much more manageable, plus you can even get that sweet looking “bokeh” at such wide aperture despite the wider FOV.

Both versions of the lens (cine and stills) feature 13 elements in 12 groups and utilise 2 Aspherical and 3 Extra-Low Dispersion elements to minimize aberration, reduce unnecessary light dispersion and deliver high resolution corner to corner.
The Ultra Multi Coating (UMC) optimizes light transmission and minimizes ghosting artifacts. The non-rotating front lens design enables the easy use of polarizing filters or ND filters. The 77mm native filter thread is a major benefit to filmmakers as this is a very popular size of ND, VariND and Polarizing filters.
I own a Genus Eclipse Variable ND and a few Hoya Pro NDs and Polarizing filters all 77mm – they fit natively on my Canon EF 24-105mm f4.0 IS zoom, which lives permanently on my Sony FS5, and now that Rokinon have gone with a 77mm native filter thread on the 20mm T1.9 makes their proposition even that much more appealing.
