Product Information

Full details

The SIRUI Venus 150mm T2.9 1.6x Anamorphic Lens is designed for filmmakers seeking a distinct cinematic look on full-frame Sony E-Mount cameras. Its primary benefit is the ability to capture a 2.8:1 widescreen aspect ratio with characteristic anamorphic flares and bokeh, but users must be comfortable with manual focus operations. This lens is part of a larger series, offering consistent color science and advanced features for high-end video production.

FAQs

What does '1.6x anamorphic' mean?

A 1.6x anamorphic lens squeezes a wider field of view horizontally onto the camera sensor. When de-squeezed in post-production or during playback, it creates a wider aspect ratio (2.8:1 from a 1.6x squeeze on a full-frame sensor) with characteristic oval bokeh and horizontal light streaks.

Is this lens suitable for still photography?

While designed for video, the lens can be used for still photography. However, the anamorphic characteristics and manual focus might make it less ideal for fast-paced still photography compared to a dedicated stills lens.

Can I achieve a 2x anamorphic look with this lens?

Yes, by combining the SIRUI Venus 150mm T2.9 1.6x lens with the optional SIRUI 1.25x adapter, you can achieve a 2x squeeze for an even more pronounced anamorphic effect.

What is the minimum focusing distance?

The minimum focusing distance is 1.9 feet (0.58 meters).

How does this lens compare to other SIRUI Venus anamorphic lenses?

The SIRUI Venus series includes lenses with different focal lengths (e.g., 35mm, 50mm, 75mm, 100mm, 135mm) and squeeze factors. This 150mm lens offers a longer focal length for tighter shots while maintaining consistent color science and anamorphic characteristics across the series.

Do I need special software to de-squeeze the footage?

Most modern video editing software (e.g., Adobe Premiere Pro, Final Cut Pro, DaVinci Resolve) can handle de-squeezing anamorphic footage. You typically need to set the footage interpretation to the correct aspect ratio or apply an anamorphic de-squeeze effect.

What is the filter thread size?

The lens has a filter thread size of M82x0.75.

Troubleshooting

Lens is not recognized by the camera.

Ensure the lens is securely mounted. Check if the camera's firmware is up to date. If using an adapter, ensure it is compatible and properly installed.

Focus is soft or inaccurate.

Practice manual focusing techniques. Use the camera's focus peaking or magnification tools. Ensure the lens is correctly seated on the mount and that you are focusing on the subject at the correct distance.

Image appears vignetted or dark around the edges.

Confirm that the lens is being used on a full-frame camera body. If on an APS-C or Super35 sensor, some vignetting is expected. Check if the aperture is set too wide for the lighting conditions.

Anamorphic artifacts (flares, oval bokeh) are too strong or undesirable.

Control light sources to manage flares. Experiment with different aperture settings; smaller apertures (higher f-numbers) can alter bokeh shape. Consider post-production adjustments to mitigate unwanted artifacts.

Pros and Cons

Pros

Achieves a true cinematic widescreen aspect ratio (2.8:1) with full-frame sensors.
Produces distinct anamorphic visual characteristics like oval bokeh and horizontal flares.
Fast T2.9 aperture is beneficial for low-light and achieving shallow depth of field.
Full-frame coverage ensures maximum image quality and compatibility with modern cameras.
Part of a series, allowing for consistent color and style across multiple focal lengths.
Supports high-resolution video formats like 8K.

Cons

Requires manual focus, which may not suit all users or shooting styles.
Anamorphic artifacts (flares, distortion) might require specific post-production handling.
The 1.6x squeeze might necessitate de-squeezing in post-production, depending on the workflow.
Larger and heavier than standard spherical lenses.
While part of a set, the 150mm focal length is specific and might not be the most versatile for all scenarios.

Setup, Compatibility & Care

Setup:

Ensure your camera body has a compatible Sony E-Mount.
Align the lens mounting index with the corresponding index on the camera body.
Gently rotate the lens clockwise until it clicks into place.
To attach filters, screw an M82x0.75 filter into the front of the lens.
For focusing, use the manual focus ring on the lens barrel. The lens features a 153° rotation angle for smooth focus transitions.

Compatibility:

Mount: Sony E-Mount. This lens is also available in RF, L, and Z mounts for broader system compatibility.
Sensor Size: Designed for Full-Frame sensors. It can be used on APS-C or Super35 sensors, but coverage will be reduced, and the aspect ratio effect will differ.

Care:

Cleaning: Use a soft, lint-free microfiber cloth to clean the lens elements. For stubborn smudges, a lens cleaning solution can be applied sparingly to the cloth, not directly to the lens.
Storage: Store the lens in its protective case or a padded camera bag when not in use. Avoid exposing it to extreme temperatures, dust, or moisture.
Handling: Always handle the lens by its body, not by the focus ring, to prevent accidental adjustments or damage. Use a tripod or support for stability, especially during long exposures or video recording.
