One of the most surprising announcements from NAB this year came from filter maker NiSi, who decided to release a set of cinema prime lenses. No, that's not a typo. And Cinema 5D's Nino Leitner was at NAB to see the lenses in person and ask the NiSi rep some questions about the lineup.

The NiSi F3 Cinema Prime lenses cover focal lengths from 25 to 100mm—25mm T2.1, 35mm T2.0, 50mm T2.0, 75mm T2.0, and 100mm T2.0—and give video shooters yet another set of relatively affordable options in a market that is quickly becoming crowded. So the main question Leitner asked was: what makes these special?

The answer is two fold. First, Nisi boasts of the artistic properties of the lenses, which produce flaring with "a lot of character" while maintaining great center resolution. And second, the lenses feature an interchangeable mount; users can swap between Sony E, Canon EF, and PL mounts using a set of standard Allen keys that can be ordered alongside the lenses.
