Part of Sirui's inaugural set of autofocus lenses designed for APS-C cameras, this black, Sony E-mount Sniper 23mm f/1.2 Autofocus Lens is an ultrafast prime with shallow depth of field and high-quality bokeh that produces sharp, in-focus imagery with clear subject isolation. The quick and accurate autofocus supports eye and object tracking, even when the subject is in motion, benefiting photographers and videographers alike. The STM motor ensures a quiet autofocus experience with minimal focus breathing, another crucial benefit for videographers. Formatted for cameras with APS-C-size sensors, the 35mm full-frame equivalence is appropriate for street photography, travel, indoor architecture, and wider scenes. The lens features high refractive elements that contribute to the unit's reduced size while enhancing optical performance and minimizing flare and ghosting. The 11-blade aperture diaphragm design contributes to the lens' soft, appealing bokeh.
