Manual focus lensmaker Samyang has announced its next APS-C lens over Facebook (login required), in the form of a 16mm f/2 lens.
The details are still a bit on the thin side at this point. As you can see in the reveal image, it's a 16mm f/2.0 with 13 elements in 11 groups, and 2 aspherical lenses and it'll take 77mm filters. In the Facebook post, Samyang Asia also released some other information, saying
The 16mm focus length with rectilinear imaging system ensure extra wide angle of view amounting to 83.1 degrees (for Nikon version and 79.5 for Canon). The big aperture opening of F2.0 ensure photographers able to use it for low light environment like night street shooting. The weight of the lens is just about 571g, as a result this lens will be a attractive carry on for architecture and landscape shooting. Please share with your friends.
With a 16mm focal length, it will have roughly the same field of view as a 24mm lens on a full-frame camera. Samyang hasn't officially announced the price or availability, but in the Facebook discussion, the company comments that it's "Expected end of June or mid of July."
What's especially curious is the mount situation for this camera. It's slated to be released for "Canon, Nikon AE, Sony A, Pentax, Canon M, Fuji X, Sony NEX, MFT & 4/3 & Samsung NX."
