The folks from B&H had a little run through with Schneider Optics and their Xenon 18mm & Cine-Xenar III 14mm lenses at NAB 2014.
At NAB 2014, Schneider Optics introduces two new wide, fast cine lenses, the Xenon 18mm T2.4 full-frame lens (available in EF, F, and PL mounts) and the Super 35-format Cine-Xenar III 14mm T2.2 lens (PL and EF versions). See the test footage at the end of the video.
