An ultrafast telephoto prime designed for APS-C-format FUJIFILM X-mount mirrorless cameras, the black Sniper 75mm f/1.2 Autofocus Lens from Sirui delivers speedy performance with eye-tracking autofocus as well as a 112.5mm full-frame equivalence. Smooth focusing adjustments can be made with the 360-degree focusing ring on the lens barrel. The lens's optical design incorporates a 15-bladed diaphragm and four high-refractive glass elements, which together provide contrast-rich imagery and smooth bokeh. The STM motor within the lens minimizes focus breathing and creates quieter autofocus, which greatly benefits video applications. Firmware updates can be downloaded via the USB-C port located on the lens mount.
