The Tokina atx-m 33mm f/1.4 X Lens for Sony E is a 50mm-equivalent prime lens designed for Sony E-mount mirrorless cameras. Featuring standard angle of view approximately equal to 50mm lenses with full-frame sensor cameras, this lens is for shooting landscapes, street scenes, and close-up 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 1.4 allows for extremely shallow depth of field and impressive low light capability. This lightweight (less than a pound) lens is ideal for travel and hiking as well. The construction also allows for extremely fast but silent auto focus. A clickless aperture ring emulates a traditional film shooting experience and the controls are smooth and functional without being cumbersome. With a minimum focus distance of 15.7", the close-up possibilities are almost endless, including food, small products and jewelry.
