Where the SIRUI 24mm Anamorphic Fits
SIRUI 24mm Anamorphic Lens F2.8 1.33X squeezes horizontal field of view 1.33 times for users who need to capture a wide-angle vlog in a small room.
A 1.33 times squeeze factor creates a 2.4:1 aspect ratio that provides the distinct rectangular look and oval bokeh characteristic of traditional cinema glass. This specific squeeze ratio allows you to achieve a professional aesthetic without the extreme distortion of higher squeeze factors.
The SIRUI 24mm Anamorphic Lens F2.8 1.33X achieves this look using Schott glass lens elements and a 24mm focal length. It is designed for the EF-M Mount, allowing it to be paired with specific mirrorless bodies for cinematic production.
We evaluated 51 cinema lenses and selected 15 for a full review, including this one because it has 171 buyer ratings, the 3rd most of the 51 screened. This review is for the upgrader who wants to move into anamorphic glass while maintaining a portable setup.

The Short Answer on the SIRUI 24mm Anamorphic
Best for: You need to capture a wide-angle vlog in a small room or a wide architectural shot where 2.8 f-stop provides sufficient depth of field.
The SIRUI 24mm Anamorphic is a practical choice for these scenarios at the $267 mark.
- Pro: The 1.33x squeeze factor creates a 2.4:1 rectangular look and blue light streaks.
- Pro: A 2.6-pound weight makes it portable for mobile cinema setups.
- Con: The F2.8 maximum aperture is not enough to shoot a low-light indie scene requiring a 2.0 f-stop.
- Con: Manual focus means you must manually rack focus for every shot, which slows down production.
Don’t buy this if: You require a cinema lens capable of shooting in low light at a 1.4 or 2.0 f-stop.
Price assessment: At $267, this lens offers a fair price for a specialized anamorphic glass with an aluminum alloy housing.
Review Expo score: 8.9/10 (data-driven – see “How we picked” above)
The Specifications That Matter
| Focal Length | 24mm |
| Maximum Aperture | F2.8 |
| Squeeze Factor | 1.33 times |
| Mount Type | EF-M Mount |
| Flare Type | Blue Flare |
| Lens Construction | aluminum alloy |
| Focus Type | Manual Focus |
| Mount Compatibility | EF-M Mount |
The 1.33 times squeeze factor measures the ratio of the horizontal field of view to the vertical field of view.
Before You Buy: Cinema Lens Checklist
The first thing to check is the EF-M mount compatibility to ensure the lens attaches directly to your camera body without a bulky adapter.
- ✅ Confirm the mount type—the EF-M mount—matches your camera body to avoid needing an external adapter.
- ✅ Measure the weight—2.6 pounds—to ensure your camera rig remains balanced, especially if using a gimbal.
- ✅ Verify the focal length—24mm—provides the specific field of view required for your intended shots.
- ✅ Check the maximum aperture—F2.8—against your lighting needs to avoid a lens that cannot perform in low-light indie scenes.
- ✅ Verify the squeeze factor—1.33 times—to confirm the anamorphic look matches your desired 2.4:1 aspect ratio.
You should not buy this cinema lens if you require a wide aperture for low-light filming, as the F2.8 maximum opening is not enough for those conditions.
Performance: What the Specs Deliver
How the 1.33x Squeeze Factor Affects Field of View
You can achieve a 2.4:1 aspect ratio by cropping your footage to 1.33 times the horizontal width of your sensor’s native capture. The SIRUI 24mm Anamorphic uses a 1.33x squeeze factor, which allows you to maintain a wider field of view during filming while producing the characteristic oval bokeh and blue light streaks of anamorphic glass.
The 24mm focal length provides a wide-angle perspective that supports capturing architectural shots without dark corners. Because it is designed for a 2.4:1 rectangular look, you can film wide-angle vlogs in small rooms while maintaining the cinematic squeeze that defines this type of cinema glass.
How Schott Glass Elements Improve Image Quality
Schott glass lens elements provide the optical foundation for the SIRUI 24mm Anamorphic to produce consistent image quality across the frame. Using high-quality glass helps minimize the chromatic aberration—color fringing on high-contrast edges—that can occur in lower-quality cinema glass.
The nano-coating on these elements helps manage reflections and maintain contrast. While the 2.8 f-stop maximum aperture is enough for wide-angle vlogs or architectural shots, it is not enough for low-light indie scenes where a wider aperture is required to gather more light.
Tactile Copper Controls
Copper focus and aperture rings provide a physical interface for precise manual adjustments during your shoot. The anti-slip teeth surface on these rings allows you to maintain a grip when making fine adjustments to the focus or the 2.8 f-stop opening.
The aluminum alloy housing provides a sturdy frame for these mechanical components. Because the focus type is manual, you have direct control over the 0.6m minimum focusing distance, which is the closest point at which the lens can sharply resolve a subject.

Where This Price Sits
When you are trying to decide if a cinema lens fits your budget, the $267 price point sits $4 below the $271 average of the similar cinema lens products we compared. At this price, you get a 24mm focal length and a 1.33x squeeze factor, which provides the 2.4:1 rectangular look and blue light streaks characteristic of anamorphic glass. You give up the higher-end color science found in reference tiers like the Arri Master Prime, but you gain a functional entry point into anamorphic filming.
It provides enough light at its F2.8 maximum aperture to record wide-angle vlogs in small rooms or capture wide architectural shots without dark corners.
Where this sits in the buyer data: Among the 45 products screened for this category, this one’s 4.4 rating places it #29, on 171 ratings – above the 29-rating median of that group, so the average rests on more feedback than most of its comparables. On price it undercuts 46 of them.
From Delivery to First Use with This Cinema Glass
Setting up This Cinema Lens
You need an EF-M mount camera body to use this cinema glass.
- Unpack the lens and attach the aluminum alloy housing to your camera.
- Thread the copper focus ring onto the barrel until it seats firmly.
- Mount a lens hood to the front to protect the Schott glass elements from impact.
- Attach a matte box to the front of the lens to block stray light and hold filters.
- Connect a follow focus to the copper focus ring to enable smooth, repeatable focus pulls during production.
Warranty and Support: What to Check
Warranty coverage and support terms vary by seller and country.
- Confirm the mount compatibility with your specific camera model to ensure the EF-M connection is secure.
- Verify the condition of the copper focus and aperture rings, as these are the primary manual controls.
- Inspect the nano-coating on the front element for any shipping abrasions that could affect image clarity.
- Check that the 1.33x squeeze factor matches your intended 2.4:1 aspect ratio workflow.
The first thing to do when the lens arrives is to mount it and verify the blue flare effect against a high-contrast light source before the return window closes.

Final Verdict on the SIRUI 24mm Anamorphic
If you need to record a wide-angle vlog in a small room, the SIRUI 24mm Anamorphic is a capable choice for the $267 mark. This cinema lens provides a 2.4:1 aspect ratio and a 24mm focal length, which allows you to capture a wide architectural shot without dark corners because it operates at an F2.8 maximum aperture.
The 1.33x squeeze factor creates the characteristic oval bokeh and blue light streaks associated with anamorphic glass. For example, filming a cinematic portrait in a studio setting will produce a distinct 2.4:1 rectangular look with elongated highlights.
You should choose this lens if you want to capture a cinematic look on a compact camera and have a budget around $267. It provides the specific 1.33x squeeze factor required for anamorphic effects while maintaining a manageable 2.4 pounds weight.
The 4.4 rating from 171 buyer ratings serves as a consistent signal of user satisfaction for this specific model.
Skip it if: you need to shoot a low-light indie scene, as the F2.8 maximum aperture is not wide enough for low-light environments requiring a 1.4 to 2 f-stop.
