Sirui Sniper Autofocus Lens 23mm in White for Fuji X-Mount with Ceramic Coating. 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 always recognized and tracked, contributing to smooth and high-quality production. The STM motor design provides a quiet autofocus experience. The 23mm lens features an ultra-fast aperture of F1.2 with 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 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 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 and strong ceramic coating make the lens robust and lightweight, weighing only 380 g.
