Daniel Gangur has done a review on the Samyang XP 50mm f/1.2 lens (known in the USA as the Rokinon SP 50mm f/1.2 lens). Gangur put this new and ultra-fast, manual focus, medium-length prime through its paces to see just how the lens stacks up in the current Samyang XP (Rokinon SP in the USA) lineup. To summarize, Gangur believes that the lens will hit a sweet spot as an ultra-fast prime that will appeal to portrait photographers and those looking for a general, high-quality 50mm lens. Astrophotography is also another area this lens will see a lot of use on Ganger’s camera, as it performs incredibly well with little coma, fringing, or astigmatism wide open.
The Samyang XP 50mm f/1.2 is a manual focus lens that isn’t fully manual exposure. The lens will control aperture via the camera body and has a chip to relay EXIF data and give focus confirmation. For those that haven’t used a lens that confirms focus, as you rack the focus, the camera auto focus points will confirm when holding your auto focus button and when the area you are focusing to becomes sharp. It’s a neat blend of manual and auto focus without the additional weight of a motor or the cost to keep this lens more affordable.

Gangur gives a great rundown of different advantages of the lens through street portraits, vignetting tests, and an astrophotography comparison, thus showing this 50mm will exceed some photographers’ hopes and may be a great alternative to Canon’s EF 50mm f/1.2L lens. If you’re looking at price-to-performance and have a Canon EOS 5DS or Canon EOS 5DS R, this is a fast prime that can resolve the images that you’re creating to the highest degree.
