Sirui Sniper Autofocus Lens 23mm silver for Nikon Z mount. If your camera supports eye-AF functionality, it makes focusing on the human eye easier, even when the subject is moving quickly. During video recording, the subject is continuously recognized and tracked, contributing to smooth and high-quality production. The STM motor design offers an almost silent autofocus experience. The 23mm lens features an ultra-fast aperture of F1.2 with a shallow depth of field, high bokeh quality, and subject isolation. The reduction of light usage in low-light conditions eliminates the need for extremely high ISO settings, allowing you to shoot perfect night scenes. A short shutter speed enhances shooting efficiency and helps capture brilliant moments in time. The lenses are made of high refractive index glass to reduce the size of the lens. Includes a petal-shaped lens hood for the 23mm lens. The premium lens body made of strong aluminum alloy makes the lens robust and lightweight, weighing only 380g.
