Sirui Sniper Autofocus Lens 33mm black for Sony E-mount made of aluminum and carbon. 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 an almost silent autofocus experience. The 33mm lens features an ultra-fast aperture of F1.2 with shallow depth of field, high bokeh quality, and subject isolation. In low light conditions, there is no need to use an extremely high ISO value, allowing you to capture perfect night scenes. A short shutter speed enhances shooting efficiency and helps capture brilliant moments in time. ED glass and high refractive index glass are used to reduce the size of the lens. Includes a petal-shaped lens hood for the 33mm lens. The sturdy aluminum and carbon body makes the lens lightweight and durable.
