Full details

FAQs

What is the minimum focus distance for this lens?

The minimum focus distance is 0.3 meters (approximately 1 foot).

Can I use this lens with my APS-C camera?

While designed for full-frame, it can be used on APS-C cameras. Be aware that it will result in a narrower field of view due to the crop factor.

How do I change the lens mount?

The lens features a user-changeable mount system. Refer to the specific instructions provided with the lens or on the Sirui website for detailed steps on safely removing and attaching different mount types.

What is the filter thread size?

The lens has a 67mm filter thread.

Does this lens have autofocus?

No, the Sirui Vision Prime 1 T1.4 Cine Lens is a manual focus lens designed for precise creative control.

What is the benefit of the T1.4 aperture?

The T1.4 aperture allows for excellent light gathering capabilities, enabling shooting in low-light conditions and providing a shallow depth of field for creative background blur (bokeh).

Is the focus breathing noticeable during video?

The lens is engineered to have virtually no focus breathing, which is critical for professional cinematic focus pulls during video recording.

Troubleshooting

Lens not focusing sharply.

Ensure the lens is properly mounted. Clean the lens elements. Verify focus ring is set to infinity for distant subjects or minimum focus distance for close-ups. Check camera's focus mode is set to manual.

Image appears distorted or has chromatic aberration.

The advanced optical design minimizes these, but extreme conditions may show slight effects. Ensure the correct mount is used and check for any physical damage to the lens.

Difficulty achieving smooth focus pulls.

Practice with the 270° focus rotation. Consider using a follow focus system for more precise control, especially for video.

Bokeh appears harsh.

The 12-blade aperture is designed for creamy bokeh. Ensure you are shooting at wider apertures (lower T-stops) and have sufficient distance between your subject and background.
