The Tokina atx-m 33mm F1.4 E - a fast fixed focal length lens for Sony E-mount mirrorless cameras. The lens with an angle of view of approx. 50mm in full frame (standard angle) was developed to serve as a versatile optical device for amateur or semi-professional photographers to capture snapshots, landscapes and environmental portraits. At 33mm, the actual angle of view is 45.7°, which is the closest to a conventional standard full-frame lens that many photographers have become accustomed to. A special optical design formula with an SD (low-dispersion) glass element ensures excellent optical performance and corrects for aberrations. The lens has a precise, responsive AF system that communicates fully with the camera body. The ST-M focus motor ensures quiet and fast focusing.
