Full details
This guide is for filmmakers and content creators seeking to achieve a distinct cinematic look. The SIRUI Saturn 50mm T2.9 1.6x Anamorphic Lens for Canon RF delivers a wide, cinematic aspect ratio and unique bokeh with its 1.6x squeeze factor, creating a signature visual style. A potential consideration is the need for post-production de-squeezing to achieve the final 2.40:1 aspect ratio. Key features include full-frame coverage, lightweight carbon fibre construction, and neutral flares for creative control.

FAQs
What is an anamorphic lens and why use one?
An anamorphic lens compresses the image horizontally during recording. This allows for a wider field of view and creates distinctive visual characteristics like oval bokeh and horizontal flares. When de-squeezed in post-production, it results in a wider cinematic aspect ratio (like 2.40:1) than standard spherical lenses typically achieve.
What does '1.6x squeeze' mean?
The '1.6x' indicates the degree of horizontal compression applied by the lens. A 1.6x squeeze factor means the image is compressed by 1.6 times its normal width. This is a common factor for achieving a 2.40:1 aspect ratio when de-squeezed.
Does this lens have autofocus?
No, the SIRUI Saturn 50mm T2.9 1.6x Anamorphic Lens is a manual focus lens. You will need to manually adjust the focus using the focus ring on the lens.
What cameras is this lens compatible with?
This lens features the Canon RF mount and is designed for use with Canon EOS R series cameras that have an RF mount.
How do I achieve the final widescreen aspect ratio?
After shooting, you must import your footage into video editing software and apply a de-squeeze effect. For this 1.6x lens, you'll typically apply a 1.6x horizontal stretch to achieve the 2.40:1 aspect ratio.
What is focus breathing?
Focus breathing is the change in the lens's field of view as you adjust focus. Anamorphic lenses, including this one, can exhibit noticeable focus breathing. It's advisable to perform focus pulls smoothly and deliberately, or avoid critical focus changes during a shot if breathing is distracting.
Are the flares customizable?
The flares produced by this lens are described as neutral, meaning they do not have a strong color cast. This allows for greater flexibility in post-production to color grade the flares or apply specific stylistic effects.
Troubleshooting
Lens not mounting to camera
Ensure you are using a Canon RF mount camera. Check for obstructions in the lens mount or camera mount. Confirm the lens is aligned correctly before rotating.
Image appears stretched horizontally
This is expected behavior of an anamorphic lens before de-squeezing. Apply a 1.6x horizontal de-squeeze in your video editing software to correct the aspect ratio.
Soft focus or blurry images
Ensure the lens is properly focused using the manual focus ring. Check if the aperture is too wide (e.g., T2.9) for the desired depth of field. Clean the front and rear lens elements.
Excessive lens flare or ghosting
Use a lens hood if available and appropriate for the shooting situation. Control light sources to minimize direct flare. Note that some level of flare is characteristic of anamorphic lenses.
Pros and Cons
Pros
- Delivers a distinct cinematic look with 1.6x anamorphic properties.
- Full-frame coverage offers versatility across compatible camera systems.
- Lightweight and durable carbon fibre build for portability.
- Neutral flares allow for creative post-production control.
- Achieves a wide 2.40:1 aspect ratio after de-squeezing.
Cons
- Requires de-squeezing in post-production, adding an extra step to the workflow.
- Anamorphic bokeh and flares might not suit every project's aesthetic.
- Focus breathing can be noticeable during focus pulls.
Setup, Compatibility & Care
Compatibility:
This lens is designed specifically for Canon RF mount cameras. Ensure your camera body is compatible with RF mount lenses.
Setup:
- Mounting: Align the lens's mounting index with the corresponding index on the Canon RF camera body.
- Gently insert the lens into the mount and rotate it clockwise until it clicks into place.
- Focusing: The lens features manual focus. Use the focus ring to achieve sharp focus. Note that anamorphic lenses often exhibit focus breathing; plan your focus pulls accordingly.
- De-Squeezing: In post-production, you will need to de-squeeze the footage. Most editing software (e.g., Adobe Premiere Pro, Final Cut Pro, DaVinci Resolve) has settings to apply an anamorphic de-squeeze effect, typically a 1.6x horizontal stretch, to achieve the correct aspect ratio (e.g., 2.40:1).
Care:
- Cleaning: Use a soft lens brush to remove dust. For fingerprints or smudges, use a microfiber lens cloth and lens cleaning solution. Avoid touching the lens elements directly.
- Storage: Store the lens in its protective case in a cool, dry place when not in use. Protect it from extreme temperatures and humidity.
- Handling: Always handle the lens by its body, avoiding excessive force on the focus ring or aperture ring.
