Sirui Sniper Autofocus Lens 23mm White Nikon Z-Mount Connection. 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 constantly recognized and tracked, contributing to smooth and high-quality production. The STM motor design provides a pleasant autofocus experience—closer, yet quieter. The 23mm features an ultra-fast aperture of F1.2 with shallow depth of field, high bokeh quality, and subject isolation. Reducing light usage in low-light conditions eliminates the need for extremely high ISO values, allowing you to capture perfect night scenes. A short shutter speed enhances shooting efficiency and helps capture brilliant moments in time. The lenses are made from 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 and strong ceramic coating make the lens robust and lightweight, weighing only 380g.
