Product Information
Full details
The SIRUI Venus 5-Lens Set for Sony E-mount is designed for professional filmmakers and videographers seeking a distinct cinematic look. Its primary benefit is the creation of sharp images with unique cinematic bokeh and blue streak effects, thanks to the 1.6x horizontal squeeze. A potential caveat is the learning curve associated with achieving the desired anamorphic aesthetic and managing the specific lens characteristics. This comprehensive kit includes five prime lenses (35mm, 50mm, 75mm, 100mm, and 150mm) with full-frame coverage, offering a uniform build and look for seamless workflow.

FAQs
What is the primary advantage of the 1.6x squeeze factor?
The 1.6x squeeze factor allows you to capture a wider field of view horizontally, enabling you to achieve a cinematic widescreen aspect ratio (like 2.35:1) when de-squeezed in post-production. It also contributes to the characteristic oval bokeh and anamorphic flares.
Can I use these lenses on a Sony APS-C camera?
Yes, these lenses are designed for full-frame coverage, meaning they will work on Sony APS-C E-mount cameras. However, please note that the effective focal length will be cropped due to the smaller sensor size.
Is the anamorphic de-squeeze done in-camera?
No, the de-squeeze process is typically done in post-production editing software. You will need to select the appropriate de-squeeze setting for your footage to display it in the correct aspect ratio.
How do I achieve a 2x anamorphic squeeze effect?
A 2x anamorphic squeeze effect can be achieved by using the optional 1.25x adapter, which, when combined with the lens's native 1.6x squeeze, results in an overall 2x horizontal squeeze.
Are these lenses autofocus?
No, the SIRUI Venus 5-Lens Set features manual focus only. This allows for precise control over focus pulling, which is often preferred in professional filmmaking.
What is the purpose of the blue streak effect?
The blue streak effect is a stylistic signature of anamorphic lenses, creating prominent blue flares when bright light sources are in the frame. It's a visual element used to enhance the cinematic quality and mood of the footage.
How durable is the included hard-shell case?
The hard-shell case is designed for robust protection, offering a durable exterior to safeguard the lenses from impacts, dust, and moisture during travel and storage.
Troubleshooting
Lens does not mount to camera
Verify that you are using a Sony E-mount camera. Ensure the red mounting dots on the lens and camera align correctly. Check for any debris on the lens mount or camera mount that might be obstructing the connection.
Images appear distorted or stretched incorrectly
This is the intended anamorphic effect. If you require a standard aspect ratio, you will need to de-squeeze the footage in post-production software. Consult your editing software's documentation for anamorphic de-squeeze settings.
Focus is soft or not sharp
Ensure the focus ring is set to manual focus. Carefully adjust the focus ring while observing your camera's display or using focus peaking if available. Confirm that the subject is within the lens's depth of field and that the lens is properly mounted.
Blue flares are too intense or not present
The intensity of flares depends on the light source. Position the light source to create the desired flare effect. If flares are absent, ensure the light is hitting the front element appropriately. For very intense flares, consider using ND filters to control exposure without affecting the light source's characteristics.

- Includes a protective hard-shell case for portability.
Cons
- Anamorphic effect may require a learning curve for optimal use.
- Blue streak flares are a stylistic choice and may not suit all projects.
- The 1.6x squeeze might require specific post-production workflows for correct aspect ratio.

- Requires adapter for 2x anamorphic squeeze, adding to cost and complexity.
Setup, Compatibility & Care
Compatibility: The SIRUI Venus 5-Lens Kit is specifically designed for cameras with the Sony E-mount. Ensure your camera model has this mount for proper physical and electronic compatibility. The lenses provide full-frame coverage, meaning they are suitable for both full-frame and APS-C Sony E-mount cameras, though the effective focal length will change on APS-C bodies.
Setup: Mounting the lenses is as simple as aligning the lens's red dot with the corresponding mark on the camera body and rotating until it clicks into place. Adjusting focus and aperture is done manually via the physical rings on each lens. For the 2x anamorphic squeeze effect, an optional 1.25x adapter needs to be purchased and fitted.
Care:
- Cleaning: Always use a lens cleaning kit specifically designed for optics. Start with a blower brush to remove loose dust, then use a microfiber cloth for gentle wiping. For stubborn smudges, use a lens cleaning solution sparingly on the cloth, not directly on the lens.
- Storage: When not in use, store the lenses in the provided hard-shell case. Ensure each lens is securely seated to prevent them from knocking against each other. Avoid exposure to extreme temperatures, humidity, or direct sunlight for prolonged periods.
- Handling: Mount and dismount lenses carefully by gripping the lens body, not the focus or aperture rings. Be mindful of the front element, as it is the most exposed part of the lens.
