SIRUI Astra Series 50mm, 75mm&100mm T1.8 1.33X Full-frame Anamorphic Cine Lens Kit (E Mount, Neutral
The SIRUI Astra Series 50mm, 75mm & 100mm T1.8 1.33X Full-frame Anamorphic Cine Lens Kit (E Mount, Neutral Flare) captures detailed shots on mirrorless cameras with full-frame and APS-C sensors. The three prime lenses with 50, 75 and 100 mm focal lengths use a Sony E-mount and are perfect for both professional and amateur work. The T1.8 aperture makes it easier to work in low-light conditions and creates significant separation between the subject and the background. The optical system includes an aspherical element, which reduces the overall size of the lens barrel while suppressing unwanted image distortion. Three-phase protection prevents dust, dirt and raindrops from getting inside the internal components when working in adverse weather.

Aperture
A T1.8 aperture makes it easy to work in low-light environments and provides scope for creative work with depth of field. An aperture adjustable up to T22 gives you control over the depth of field in every shot. Users can shoot without increasing the ISO, which prevents significant digital noise. The optical system delivers consistent results when shooting and photographing in a variety of lighting conditions.
Fast STM focusing
The autofocus uses a quiet and smooth STM stepping motor to maintain clean audio recording directly to the camera. A switch on the body allows you to quickly switch between automatic and manual focus modes without having to go through the camera menu. This focusing system is suitable for shooting dynamic videos as well as creating static portraits. The motor responds quickly and accurately tracks moving subjects in the frame.
Aperture control for video and photos
The aperture control ring offers a choice between a smooth, clickless action for video and a stepped, clicking action for photography. An aperture lock prevents the control ring from being accidentally turned when handling or carrying the equipment. The quiet, clickless action is suitable for smooth exposure changes directly during a scene. This allows users to react subtly to changing light conditions without any distracting audio in the video recording.
Integration into video systems
The unified placement of the gear rings makes it easy to change optics on gimbals, drones and camera cages without having to readjust accessories. Identical colour rendering simplifies post-production and colour matching of individual shots from different focal lengths. Users do not have to recalibrate follow-focus systems when changing lenses.
Accessory compatibility
The front of the barrel has a 67mm filter thread and an outer diameter of 72mm. The customisable FN button lets you assign selected functions according to the individual needs of the camera operator or photographer for faster control. The lens is fully compatible with commonly available filters and LiDAR focusing systems. A built-in dual scale in metres and feet facilitates precise manual focusing and distance control.
