Night Walker 55mm – SIRUI Night Walker Series cine lenses come in S35 coverage. The Night Walker 55mm is equivalent to a 77mm full frame lens, suitable for close-ups, portrait filming. Note: The frame is Super35 mode, and there may be dark corners when used on a full-frame camera. When using a full-frame lens, the camera mode needs to be adjusted to APSC/S35 mode to get better footage. Or you could choose SIRUI VP-1 T1.4 cine lens, it is a full frame lens with E/L/RF/Z mounts.
Low-light monster: Enjoy superb low-light capabilities and profound depth of field control. The T1.2 aperture allows for drastic ISO reduction in extremely dark environments, reduces noise, captures tranquil night scenes, and produces exquisite bokeh, achieving perfect sharpness, minimal focus breathing, and well-controlled aberrations.
Excellent Close Focus Distance: At a close focus distance of 0.6m, this lens lets you get deep into the details of your subject, opening up the world of macro photography with impeccable precision and clarity.
Ultra-long 270° focus travel: NightWalker series cinema lenses have a 270° focus travel, which provides more precise focus control to maximize accuracy. This is essential for movie shooting that requires precise control of focus.
Well-constructed and Lightweight: The solid aluminum cine housing makes it durable and light. The minimum weight of each single lens is only about 500 grams, which can usher in a new era of lightweight fast aperture lenses. The gear ring is damped smoothly and uses the same gear design to support follow focus operation, ensuring that there is no need to re-install the stabilizer and follow focus or readjust them when using the same series of cine lenses during shooting.
