Product Information
Full details
This SIRUI Jupiter Macro Cine Prime Lens Set is designed for professional videographers and filmmakers using full-frame cameras with Canon EF mounts. It offers exceptional sharpness for detailed macro shots, a fast T2 aperture for low-light performance and shallow depth of field, and consistent handling across the three included focal lengths (24mm, 35mm, 50mm). A key caveat is its specialized nature, best suited for projects requiring high-quality close-up cinematography rather than general-purpose shooting. The set boasts 8K resolution readiness, minimal focus breathing, and a uniform design for seamless lens changes.

FAQs
What is the minimum focus distance for these lenses?
The minimum focus distance for all three lenses (24mm, 35mm, 50mm) in the SIRUI Jupiter Macro Cine Prime Set is 0.24 meters (approximately 0.79 feet).
Can these lenses be used on mirrorless cameras?
Yes, they can be used on mirrorless cameras with the appropriate EF-to-your-camera-mount adapter. Ensure the adapter is designed for full-frame sensors if applicable.
What does 'focus breathing' mean and how is it handled?
Focus breathing is the change in field of view when adjusting focus. These lenses are engineered to minimize this effect, providing smoother focus transitions for cinematic use. However, extremely rapid focus pulls may still show minor changes.
How do the T-stops differ from F-stops?
T-stops (Transmission stops) measure the actual amount of light transmitted through the lens, accounting for light loss within the lens elements. F-stops are a theoretical calculation. T-stops are considered more accurate for consistent exposure in cinematography.
Are filters compatible with these lenses?
Yes, each lens in the set features a 92mm filter thread on the front, allowing for the use of standard filters.
What is included in the lens set?
The set includes the SIRUI Jupiter 24mm T2, 35mm T2, and 50mm T2 Macro Cine full-frame lenses, along with three lens caps, three lens back caps, and a protective hard carrying case.
Can I buy individual lenses from this set?
The product information provided indicates a set is offered. Individual lens availability may vary, but the set is designed for users needing the full range for cohesive projects.
Troubleshooting
Lens not focusing smoothly
Ensure the lens is correctly mounted to the camera and that no adapters are causing misalignment. Check if the focus ring is obstructed or damaged. For manual focus, ensure it's set to the desired focal point.
Image is consistently soft or blurry
Verify that the correct aperture (T-stop) is selected. Ensure the lens is clean and free of dust or smudges on the elements. Confirm that the camera's focus is accurately set to the subject, especially when using manual focus.
Focus breathing is noticeable
While the lenses minimize breathing, extreme focus pulls may still exhibit some. Practice smoother, slower focus transitions. For critical shots, consider using a geared follow focus system for more precise control.
Difficulties changing lenses quickly
Familiarize yourself with the uniform gear positions. Ensure lens caps and body caps are easily accessible. Practice the lens-swapping procedure to become more efficient.

Setup, Compatibility & Care
Setup: This lens set is designed for Canon EF mount cameras. Ensure your camera body has a compatible Canon EF mount. For mirrorless cameras, use a suitable EF-to-your-mount adapter. Mount the lens by aligning the red dot on the lens with the corresponding mark on the camera mount and rotate clockwise until it clicks into place.
Compatibility: The lenses are full-frame compatible. While designed for Canon EF, adapters are available for use with various mirrorless camera systems (e.g., Sony E-mount, Fujifilm X-mount). Check adapter compatibility for your specific camera model.
Care:
- Cleaning: Use a soft microfiber lens cloth to gently wipe the lens elements. For stubborn smudges, use a lens cleaning solution sparingly on the cloth, never directly on the lens. Always clean from the center outwards.
- Storage: Store lenses in the provided hard case when not in use to protect them from dust, moisture, and physical impact. Ensure lens caps are securely attached.
- Handling: Avoid touching the lens elements with your fingers. Mount and dismount lenses carefully by holding the lens body, not the front element.
- Environment: Protect the lenses from extreme temperatures and humidity.
