Today Tokina announced a brand new series of lenses for Sony E-mount called Firin. The first lens in the series is the 20mm f/2.0, a super-wide ultra-fast manual prime. Both compact and lightweight, it is a perfect match for Sony’s A7 bodies.
The lens promises excellent optical performance with reduced aberrations and high resolution/contrast thanks to its two all-glass precision molded aspherical elements with 3 Super-Low Dispersion (SD) glass lens elements. It has the ability to encode and transmit aperture, distance and optical data to the camera body, and comes with a wide manual focus ring, de-clicking aperture ring and depth of field index bar on the barrel.
Although a release date hasn’t been officially stated, it is suspected that the lens will arrive in early 2017.
