Excellent Close Up Performance: the closest focusing distance is about 0.22m, the maximum magnification is about 0.1 times, it supports close up, and with F1.4 large aperture blur effect, the subject is prominent. With the 13mm super wide angle, you can easily create visually stunning photos and videos. Excellent High Resolution Performance: 11 groups of 14 optical structure design, 2 aspherical lenses, optimized distortion performance and off axis optical aberration, so that the lens maintains high definition performance in the entire imaging range. 4 ED, low dispersion, lenses can effectively improve magnification chromatic aberration, reduce radial glare, accurately display point light sources, and ensure excellent contrast and accurate color reproduction at various aperture values. Video Optimized Design: AF 13mm F1.4 Z is optimized for video shooting, internal focus design, slight breathing effect, and support for eye controlled focusing, suitable for micro movies, vlogs, scenery time lapse, event shooting, architectural photography, wedding scenes and other video shooting Scenes. Extremely Fast and Accurate Autofocus: The combination of internal focus and STM and screw type stepping motor is used to achieve fast, accurate and quiet autofocus through the optimization and adaptation of the camera's autofocus algorithm, and to track the subject quickly and sensitively. Take control of dynamic photo and video with ease. Super Wide Angle: F1.4 large aperture soft focus, 13mm super wide angle visual impact, electronic aperture, internal focus, lens length unchanged. Accurate metal structure, sturdy and durable all metal lens body structure, to ensure the assembly accuracy and durability of the lens, and brass metal mount, closely fit the body.
