The Sirui Night Walker 55mm is a fixed-focal-length, manual focus cine lens for S35 and APS-C cameras. It has a maximum aperture of T1.2, which allows shooting in low light without extremely high ISO. On an S35/APS-C frame, 55mm is equivalent to a 77mm full frame lens, suited to close-ups and portraits.
The lens has 11 elements in 10 groups, including aspherical, ED and high refractive index glass, which keeps focus breathing minimal and distortion controlled. It has 12 aperture blades and a stepless aperture ring for smooth operation. The body is aluminum alloy.
The lens is sharp at its maximum aperture and produces pleasing bokeh with a clear subject. The Night Walker series is compatible with Sony, Fuji, Canon and other cameras.
