This Tokina atx-m 56mm f/1.4 Lens for Sony E-Mount features an angle of view approximately equal to 85mm lenses on full-frame sensor cameras. This lens is for amateur and professional photographers shooting portraits, street scenes, and low-light photos. The atx-m series is designed with low-dispersion glass elements that provide sharp focus, high contrast, and low distortion. The minimum aperture of f/1.4 allows for an extremely shallow depth of field and impressive low-light capability. This lightweight lens is ideal for travel, hiking, and exploring. The construction also allows for extremely fast but silent autofocus. The clickless aperture ring emulates a traditional film shooting experience, and the controls are smooth and functional without being cumbersome.
