Can the SIRUI 24mm Anamorphic Cinema Lens produce a cinematic portrait with a blurry background?

You need a subject at least 0.6m away to achieve this effect, so start by marking your closest focal point to ensure the subject remains sharp.

The SIRUI 24mm anamorphic lens creates oval bokeh and 2.4:1 aspect ratios

This lens uses an anamorphic element to squeeze the horizontal field of view 1.33 times, creating a 2.4:1 aspect ratio and a distinct oval bokeh—the out-of-focus highlights that appear as elongated ovals rather than circles. While many buyers assume a wide-angle lens cannot isolate a subject, the F2.8 opening allows for a manageable depth of field. Note that the lens does not state a specific physical stop or “sweet spot” to avoid corner vignetting, so you should check your specific framing to ensure the corners of your portrait remain clear.

What to Check Before Buying the SIRUI 24mm Anamorphic

Because anamorphic glass behaves differently than standard glass, verify these technical details for your specific shooting environment before purchasing:

For common technical questions, see the SIRUI 24mm Anamorphic FAQ section.

• Confirm your camera sensor supports a 2.4:1 aspect ratio to avoid heavy cropping or letterboxing in your final export.
• Check your lighting setup to see if you need a matte box or filter thread to manage the blue light streaks and flares characteristic of this lens.
• Verify that your shooting space allows for the 5.04 x 2.91 x 2.91 inch dimensions of the lens housing.
• Ensure your camera body is compatible with the EF-M mount, as this is the mechanical connection method for the lens.

Comparing the SIRUI 24mm Anamorphic to Other Options

The SIRUI 24mm Anamorphic is a specialized piece of glass—a lens that stretches the image horizontally to create a wide, cinematic look—designed for those prioritizing the anamorphic aesthetic over extreme low-light performance. Because it sits at an F2.8 aperture, it provides enough depth of field for vlogs or architectural shots, but it may not be the right choice for high-end commercial work requiring very shallow depth of field in dim environments. If you need to shoot in extremely low light or require a wider maximum opening than F2.8, you should look at lenses with a lower f-number.

To see how it stacks up against rivals, view the SIRUI 24mm Anamorphic comparison guide.

If you primarily need to record wide-angle vlogs or capture architectural shots with a cinematic squeeze, the SIRUI 24mm Anamorphic is a strong choice. However, if your goal is to shoot in very low light or requires a much shallower depth of field than F2.8 provides, you should consider a lens with a wider maximum aperture.
