Product Information

Full details

The SIRUI 40mm T1.8 1.33X S35 Autofocus Anamorphic Lens is designed for filmmakers and photographers seeking to achieve a cinematic widescreen look with the distinctive aesthetic of anamorphic lenses. Its key benefit is the combination of autofocus capabilities with a fast T1.8 aperture, enabling creative shots in low light and precise focus control. A potential caveat is the need for specific post-production workflows to de-squeeze the 1.33x image, and understanding the lens's characteristics for optimal results.

Extended Product Information

FAQs

What is the purpose of the 1.33x squeeze factor?

The 1.33x squeeze factor is a key characteristic of anamorphic lenses. It horizontally compresses the image onto the camera sensor, allowing for a wider field of view (2.35:1 aspect ratio) when the footage is de-squeezed in post-production. This creates the distinctive cinematic widescreen look.

Can I use this lens for still photography?

Yes, the SIRUI 40mm T1.8 lens can be used for still photography. It offers manual focus control and the option for clicked aperture settings, making it suitable for a wide range of photographic applications, including portraits and landscapes, with the unique anamorphic aesthetic.

How do I choose between the blue and neutral flare options?

The neutral flare provides a more subtle light streak effect, generally suitable for a wider range of scenes. The blue flare offers a more pronounced blue-tinted streak, often used for specific stylistic choices in sci-fi, mystery, or dramatic scenes to enhance the mood.

What is the difference between this autofocus lens and manual anamorphic lenses?

The primary difference is the inclusion of an autofocus system. Manual anamorphic lenses require precise manual focusing, often needing a focus puller for smooth transitions. This autofocus version simplifies focus control, making it more accessible for single operators and faster-paced shooting scenarios.

How do I handle the 'B-Ware' condition mentioned?

B-Ware indicates an item that is fully functional and has passed technical inspection, but may have minor cosmetic imperfections or damaged original packaging. It comes with a 2-year warranty, similar to new items, but is not eligible for other discount promotions.

What is the minimum focusing distance?

The product information does not specify the minimum focusing distance. For precise measurements, refer to the official SIRUI product specifications or user manual.

Which camera models are best suited for this lens?

The lens is compatible with cameras featuring E, X, Z, and MFT mounts. Its S35 format coverage makes it ideal for Super 35mm sensors, but it can also be used on full-frame cameras with a crop factor or vignetting depending on the specific camera and shooting mode.

Troubleshooting

Autofocus is slow or inaccurate.

Ensure the lens is set to 'AF' mode. Check for and install the latest firmware update for your specific camera mount. Clean the camera's lens mount contacts.

Image appears stretched or distorted.

This is the characteristic effect of an anamorphic lens. You will need to de-squeeze the footage in post-production software (e.g., Premiere Pro, DaVinci Resolve) to achieve the correct 2.35:1 aspect ratio. Ensure your software settings are configured for 1.33x de-squeezing.

Lens aperture is not changing.

Verify that the click/de-click switch is in the desired position. If using the de-click mode, ensure your camera's exposure settings are correctly configured. If the issue persists, check for firmware updates or contact support.

No communication between lens and camera.

Ensure the lens is properly seated on the camera mount. Clean the electronic contacts on both the lens and camera mount. Try updating the lens firmware.

Blurry images even at correct focus distance.

Check for smudges or dust on the front lens element. Ensure the focus ring is set correctly or that autofocus is functioning as intended. Verify that the camera's shutter speed is appropriate for the lighting conditions.

Pros and Cons

Pros

Provides autofocus for easier subject tracking and run-and-gun shooting.
Achieves a true cinematic 2.35:1 aspect ratio with a 1.33x squeeze factor.
Fast T1.8 aperture excels in low-light conditions and creates shallow depth of field.
Offers creative flare options (blue/neutral) for unique visual styles.
Compact and lightweight design enhances portability and usability on various rigs.
High-quality optics minimize aberrations for a clean, cinematic image.

Cons

Requires post-production de-squeezing to achieve the intended aspect ratio.
Autofocus performance may vary depending on camera body and firmware.
The unique bokeh at T1.8 may not suit all shooting styles.
While compact, anamorphic lenses can be more complex to use than spherical equivalents.
Specific firmware updates may be required for optimal performance with certain camera mounts.

Setup, Compatibility & Care Instructions

Compatibility: This lens is available for various camera mounts including Sony E, Fujifilm X, Nikon Z, and Micro Four Thirds (MFT). Ensure you select the correct mount for your camera system. Check for firmware updates via the Type-C port to ensure optimal performance with your specific camera, especially for autofocus functions. The lens features a standard 77mm filter thread and an 80mm front outer diameter, making it compatible with most standard matte boxes.

Setup:

Mount the lens carefully onto your camera body, aligning the mount indicators.
For autofocus operation, ensure the AF/MF switch on the lens is set to 'AF'.
If using manual focus, switch to 'MF' and utilize the focus ring.
The aperture can be controlled via the de-click/click switch. For video, use the de-click (stepless) option; for stills, the click option provides tactile feedback.
For custom function buttons (like AFL on some mounts), refer to your camera's manual for setup.

Care:

Cleaning: Use a soft, lint-free microfiber cloth to clean the lens elements. For stubborn smudges, use a lens cleaning solution sparingly on the cloth, never directly on the lens. Avoid touching the glass with your fingers.
Storage: Store the lens in its protective case when not in use. Keep it away from extreme temperatures, humidity, and dust. Always attach the front and rear lens caps.
Firmware Updates: Periodically check the SIRUI website for firmware updates. Connect the lens to your computer via its Type-C port and follow the provided instructions to install updates. This is crucial for maintaining autofocus performance and compatibility.
