Samyang originally displayed a prototype 10mm prime lens at Photokina 2012 with a few details. They recently announced the official development of their new 10mm f/2.8 prime lens. If you’re not familiar with the Samyang line of lenses, they’re a very confusing bunch which shares it’s designs with different branding such as Rokinon, Bower, Vivitar, etc. Rokinon offers their photo lenses in a cinema variety that feature 32-pitch focus and iris gears as well as a smooth, click-less aperture and T-stop markings instead of f-stop. Needless to say, this new 10mm will make it’s way into a Rokinon Cine Prime flavor soon enough. There are quite a few interesting details about this lens.
First, and possibly most important, it’s designed for APS-C and Super 35 format cameras similar to their 16mm T2.2 lens recently released. This is a shift away from their early lenses including the 8mm T3.8, 24mm T1.5, 35mm T1.5, and 85mm T1.5 which were all designed to cover a 35mm full-fame (24×36) sensor. It’s not difficult to assume why Samyang decided to go this route. There’s a huge demand in the APS-C DSLR and mirrorless market at the moment and designing a such a wide angle lens to cover a full frame sensor would require a much larger, more expensive lens. Speaking of design, let’s get to some of the details of this new lens.
The 10mm will be a rectilinear lens which means that you won’t have the fisheye style of the 8mm and only minimal geometric distortion throughout the field. It’ll have a respectable maximum aperture of f/2.8 (likely a T3 for the cine-version), comprised of 14 elements in 10 groups including two aspherical elements and a single extra-low dispersion element. A removable hood has been incorporated which I’m sure was a request from many users after the 14mm was produced with it’s fixed sunshade. The lens will also have a few new tricks from Samyang such as their Nano Crystal Anti-Reflection Coating System which is simply fancy talk for coatings that reduce flares and keep the T-stop decent. The lens will produce a very nice 109.5° field of view on APS-C sensors with a minimum focus of about 10″. Other than that, you can expect the usual from Samyang and Rokinon – a plastic housing to keep manufacturing costs down and a wide range of mount options including Canon EF & M, Nikon F, Sony A & E, Pentax, Samsung NX, and Fuji X mount. Pretty much everything EXCEPT PL. …But who cares. If you’re using a PL mount camera, you should be using something a bit more reliable than a Samyang lens anyway.
