SIRUI 50mm Anamorphic Lens captures low light at f/1.8 aperture

This lens uses 11 glass elements to produce a 2.4:1 cinema format, which creates the horizontal sci-fi reflections and oval bokeh typical of anamorphic glass. Because it captures light at f/1.8, it meets the requirements for filming low-light indie scenes, cinematic portraits, or high-end commercials where a wide opening is necessary. We selected this lens for our comparison because it offers a wide 33% field of view compared to standard 50mm glass while maintaining a compact 106.6 mm length. For cinema work, low-light performance is critical because anamorphic flares and bokeh effects are most striking when the sensor receives enough light to render these optical artifacts clearly without excessive noise.

You can see how the SIRUI 50mm Anamorphic performs in various shooting scenarios.

Review our final thoughts in the SIRUI 50mm Anamorphic final verdict.

• Verify your camera body supports the MFT, m4/3, or Micro Four Third Mount to ensure a secure mechanical connection.
• Calculate your required de-squeeze—the process of stretching the image horizontally to fill a standard frame—based on the lens’s specific squeeze ratio.
• Check your rig’s physical clearance to ensure the 61.7 mm focus ring and 106.6 mm body length fit your camera cage or accessories.
• Note that the lens uses manual focus, meaning you must be able to turn the ring 143° to find your subject.
