The sequel to the successful 11-16mm Tokina zoom lens, the parfocal 11-20mm is just as compact and durable with 4 more millimeters of focal length. It's state-of-the-art design significantly reduces chromatic aberrations while offering stunning image quality even at an ultra wide angle of view. With S35 sensor coverage, standard 0.8 mod gears on all three axes, and a weight of 2.4 lbs, this is another great lens option for gimbal work.
