Product Information

Full details

The Sirui Saturn T2.9 1.6x Anamorphic Lens Kit is designed for filmmakers seeking a compact, lightweight, full-frame anamorphic solution. Its key benefit is achieving a cinematic widescreen aspect ratio with distinctive anamorphic flares and bokeh in a portable package. A potential caveat is its fixed focal lengths, requiring lens changes for different perspectives.

FAQs

What aspect ratio does this lens produce?

With a 1.6x squeeze factor, the lens produces a 2.4:1 aspect ratio on 3:2 sensors and a 2.8:1 aspect ratio on 16:9 sensors after de-squeezing in post-production.

Is this lens suitable for full-frame cameras?

Yes, the Sirui Saturn T2.9 1.6x Anamorphic Lens is designed for full-frame sensors.

How do I de-squeeze the footage?

You will need to apply a de-squeeze effect in your video editing software. Most professional NLEs (Non-Linear Editors) like DaVinci Resolve or Adobe Premiere Pro have built-in settings for anamorphic lenses, or you can use third-party plugins.

Can I use this lens on an APS-C or Super35 camera?

Yes, the lens can be used on smaller sensor formats. However, the field of view will be narrower, and the resulting aspect ratio may differ.

What is the difference between the 'Neutral Flare' and 'Blue Flare' versions?

The 'Neutral Flare' version produces more natural-looking flares that mimic classic anamorphic lenses, while the 'Blue Flare' version is optimized to create distinct, often vibrant blue horizontal flares, popular in sci-fi and modern cinematic styles.

How much does the lens kit weigh?

The lens is designed to be very lightweight, weighing under 500g.

Are the focus and aperture gears standardized for follow focus systems?

Yes, the Saturn Series lenses feature consistent gear positions for both focus and aperture, making them compatible with standard cinema follow focus accessories.

Troubleshooting

Lens does not mount to camera.

Verify that the lens mount type (e.g., L-Mount) matches your camera body. Ensure there are no obstructions or damage to the mount on either the lens or the camera. Clean both mounts gently.

Image appears 'squashed' or distorted.

This is expected anamorphic behavior. The image needs to be de-squeezed in your video editing software. Apply the appropriate de-squeeze setting for a 1.6x anamorphic lens to achieve the correct aspect ratio.

Flares or bokeh are not as expected.

Anamorphic effects are heavily influenced by the light source. Ensure you are shooting with strong light sources entering the lens at an angle. Different light sources and angles will produce varied flare patterns.

Focus breathing is noticeable.

While designed to minimize focus shift, some degree of focus breathing may still occur, especially during large focus pulls. Try to keep focus adjustments smooth and deliberate. For critical focus, consider using a focus puller.

Pros and Cons

Pros

  • Extremely lightweight and compact for easy handling and mobility.
  • Achieves a desirable 1.6x anamorphic widescreen look.
  • Produces pleasing oval bokeh and characteristic anamorphic flares.
  • Consistent gear placement for quick lens changes.
  • Matched color science across the lens set.
  • Designed to minimize common anamorphic optical issues like focus shift.

Cons

  • Fixed focal lengths mean lens swaps are required for different shots.
  • Requires de-squeezing in post-production to achieve the final aspect ratio.
  • As with many anamorphic lenses, sharpness may be reduced at the extreme edges of the frame.
  • The T2.9 aperture is moderate; low-light performance might be limited compared to faster lenses.

Setup, Compatibility & Care

Compatibility: This lens kit is available in various mounts, including the specified L-Mount. Ensure your camera body is compatible with the chosen lens mount. The kit is designed for full-frame sensors but can also be used on APS-C or Super35 sensors, which will affect the resulting field of view and aspect ratio.

Setup: Mount the lens securely onto your camera body following the standard lens mounting procedure for your camera system. Attach any necessary accessories, such as follow focus units, to the lens's geared rings. Remember that footage will require de-squeezing in post-production software (e.g., Adobe Premiere Pro, DaVinci Resolve) to achieve the intended widescreen aspect ratio.

Care: Store the lens in a protective case when not in use. Avoid touching the lens elements directly. Clean lens elements using a dedicated lens cleaning solution and a microfiber cloth, wiping gently in a circular motion from the center outwards. Protect the lens from extreme temperatures, moisture, and dust. When cleaning the carbon fiber barrel, use a dry or slightly damp microfiber cloth.
