Sirui Sniper autofocus lens 23mm white Sony E-mount made of aluminium. - If your camera supports the eye AF function, this makes it easier to focus on the human eye, even if the subject is moving quickly. When recording video, the subject is always recognised and tracked, which contributes to a smooth and high-quality production. - STM motor design brings you a pretty autofocus experience. Closer, but quieter. - The 23mm has an ultra-fast F1.2 aperture with shallow depth of field, high bokeh quality and subject isolation. - Reducing the use of light in low light conditions means there is no need to use an extremely high ISO value, allowing you to shoot perfect night scenes. A fast shutter speed improves shooting efficiency while helping to capture brilliant moments in time. The lenses are made of high refractive index glass to reduce the lens size. - Includes petal-shaped lens hood for the 23 mm lens Premium lens body - The strong ceramic coating makes the lens robust and lightweight. As a result, it weighs only 380gr Technical details: Item dimensions 12 x 8 x 8 cm Brand name SIRUI Built-in components 11 elements in 10 groups Maximum focal length 23 millimetres Minimum focal length 23 millimetres Manufacturer designation 23AS12E-W Scope of delivery: Sirui Sniper 23mm lens white E-mount connection Etui.
