[Update]: These are now available to order.
But now they're looking to take on the likes of Zeiss, Canon, and Schneider with true cine lenses that can cover full-frame/Vista Vision (but for less money than those others).
The company is expected to announce next week a new set of primes by the name of XEEN, and they look to be a much higher end product than what it currently offers. It looks like the new set, when formally announced on August 10, will consist of three lenses: a 24mm, 50mm, and 85mm, all with a constant aperture of T/1.5. We've also got more info from another source that these will have metal bodies, consistent focus marks (with unified focus/apertures positions), unified 114mm front diameters, 11 bladed aperture, and much longer focus throws than the previous set of cine primes. Also it looks like they will weigh in around the 2.5 pounds or so each.
Cinescopophilia managed to get some early photos of the new XEEN lenses. Here's what we've got so far:
And here is a bit more information on Twitter:
It looks like the XEEN primes will be offered in all of the same mounting options as their other lenses, so you can expect an Canon EF mount, Nikon F, Sony E, and Micro Four Thirds. However, they're also going to offer a PL version, which is fantastic. No word on whether the optics of these are brand new, or whether they're just rehoused versions of their current lineup, but they will cover full-frame.
These lenses are expected to cost around $2500 each (though it's possible they could list for higher), which puts them well beyond the prices that Samyang/Rokinon are known for. However, they're still significantly less expensive than competing options like the Zeiss CP.2, Canon Cine primes, and Schneider Xenon primes, all of which cost $4,000 to $5,000 a pop.
Rokinon is the US name for the Samyang lens brand, distributed by Elite Brands here.
