Product Information
Full details
The SIRUI Saturn 50mm T2.9 1.6x Anamorphic Lens for Sony E-Mount is designed for creators seeking a distinct cinematic look with its full-frame coverage and neutral flares. Its lightweight carbon fiber construction makes it ideal for handheld, gimbal, or drone use, offering a 1.6x squeeze factor for characteristic oval bokeh and horizontal field of view compression. While it provides a professional aesthetic, users should be aware that anamorphic lenses require post-production de-squeezing to achieve the correct aspect ratio.

FAQs
What is the benefit of the 1.6x squeeze factor?
The 1.6x squeeze factor is key to achieving the characteristic anamorphic look, producing oval bokeh, cinematic widescreen aspect ratios (like 2.4:1), and horizontal lens flares. It allows you to capture more horizontal information than a standard spherical lens of the same focal length.
Do I need special software to edit footage from this lens?
Yes, you will need editing software that supports de-squeezing anamorphic footage. Most professional editing suites (e.g., Adobe Premiere Pro, Final Cut Pro, DaVinci Resolve) have settings to correct the aspect ratio of 1.6x anamorphic footage.
Is this lens suitable for low-light videography?
With a T2.9 aperture, it offers good light-gathering capabilities for low-light situations, especially when combined with the wider field of view provided by the anamorphic format.
What does 'neutral flare' mean?
Neutral flares are less stylized and appear as softer, more subtle streaks or glows when light sources hit the lens directly. This contrasts with blue flares, which are more pronounced and common in anamorphic lenses, offering a different aesthetic choice.
How does the carbon fiber construction benefit me?
The carbon fiber front barrel significantly reduces the lens's weight. This makes it easier to handle for extended periods, mount on gimbals, drones, or handheld rigs without causing undue strain or affecting stabilization performance.
Can I use this lens on non-Sony E-Mount cameras?
This specific variant is designed for Sony E-Mount. SIRUI offers the Saturn series in other mounts (L-Mount, Z-Mount, X-Mount), so you would need to acquire the version with the appropriate mount for your camera system.
What is the equivalent field of view on a full-frame sensor?
On a full-frame sensor with a 3:2 aspect ratio, the horizontal field of view is equivalent to approximately a 47mm spherical lens. For a 16:9 aspect ratio, it's equivalent to about a 22mm spherical lens.
Troubleshooting
Image appears stretched or distorted horizontally.
This is expected before de-squeezing. Ensure your editing software or camera's monitoring settings are configured to de-squeeze the 1.6x anamorphic image to the correct aspect ratio (e.g., 2.4:1).
Lens does not seem to mount correctly.
Verify that you are using the correct mount for your camera. Ensure the alignment dots on the lens and camera body match, and twist the lens firmly until it clicks into place. Do not force the lens.
Focus is consistently soft.
Check that the focus ring is set correctly and that you are achieving accurate focus. Use magnification on your camera's live view or an external monitor to confirm critical focus, especially with shallow depth of field.
Internal elements appear dusty or have condensation.
Condensation may occur if the lens is moved between significantly different temperature environments. Allow the lens to acclimate to the room temperature for several hours in its case before removing it. For internal dust, professional cleaning may be required.
Pros and Cons
Pros
- Delivers a distinct cinematic look with anamorphic bokeh and flares.
- Lightweight carbon fiber build enhances portability and usability on gimbals/drones.
- Full-frame coverage provides flexibility with various camera bodies.
- Consistent gear placement across the Saturn series simplifies multi-lens setups.
- Neutral flares offer a professional, less distracting aesthetic.
Cons
- Requires de-squeezing in post-production to correct the image aspect ratio.
- 1.6x squeeze might be less pronounced than higher squeeze factors for some desired looks.
- Lens hood is not typically included and may be necessary for flare control in bright conditions.
- Limited depth of field at wider apertures can require careful focus pulling.
Setup, Compatibility & Care
Setup:
- Attach the lens to your Sony E-Mount camera body by aligning the red or white dot on the lens with the corresponding dot on the camera mount.
- Twist the lens clockwise until it locks into place.
- Ensure the aperture ring is set to your desired setting. The lens features a de-click mechanism for smooth aperture adjustments.
- Set your camera to manual focus mode.
- Configure your camera's recording settings or monitor display to de-squeeze the image for a correct aspect ratio (e.g., set aspect ratio in monitor to 1.6x or 2.4:1).
Compatibility:
This specific variant is designed for Sony E-Mount cameras.
Care:
- Cleaning: Use a soft-bristled brush or compressed air to remove loose dust from the lens elements. For smudges, use a lens cleaning solution with a microfiber cloth, wiping in a circular motion from the center outwards.
- Storage: Store the lens in its protective bag or a padded camera bag when not in use to prevent dust and physical damage.
- Environment: Avoid extreme temperatures and humidity. Protect the lens from direct water exposure.
- Handling: Always handle the lens by its body, not the front element or lens hood.
