Compared to a traditional 50mm APS-C lens, the new SIRUI 50mm F1.8 camera lens produces a cinematic 2.4:1 video with a 33% increase of the horizontal field of view. This effectively changes the FOV to be equivalent to an APS-C 37.5mm lens.


The F1.8 anamorphic lens delivers the smooth horizontal brushed and backlighting effects. And with a simple turn of the aperture ring, it will optimise the depth of view and oval bokeh effect.

Quality Compact Fit

Built with aircraft aluminium alloy during a high precision CNC process, this high-quality, durable portable anamorphic lens only weighs approximately 560g and is ready to fit onto a selection of lens mounts.

Compatible with APS-C cameras

Available in three mounts: X-mount, E-mount and M4/3 mount. The lens can attach to most APS-C cameras and select full-frame cameras.
