FAQs

Is this lens compatible with APS-C sensors?

Yes, while designed for full-frame, it will function on APS-C sensors with a corresponding crop factor increase in effective focal length.

Does this lens feature autofocus?

No, this is a dedicated manual focus cine lens designed for professional production environments.

Can I use standard 82mm filters?

Yes, the lens includes an integrated 82mm filter thread for standard photographic screw-on filters.

What is the primary benefit of the 180-degree focus throw?

The longer rotation angle allows for more precise and fluid focus pulls compared to standard photographic lenses.

Is this lens weather-sealed?

The lens features a robust, durable metal construction, but it is not classified as fully weather-sealed; exercise caution in extreme moisture or dust.

Troubleshooting

Difficulty mounting to the camera body

Verify that the lens mount alignment pins are clear of debris and that the lens is rotated until the locking mechanism engages fully.

Focus ring feels stiff during operation

Ensure no external accessories, such as matte boxes or gear rings, are causing physical friction against the barrel.

Pros and Cons

Pros

  • Exceptional 8K-ready optical clarity
  • Fast T1.5 aperture for low-light performance
  • Industry-standard gear placement for focus and iris
  • Rugged all-metal construction for field durability
  • Uniform color science for efficient grading

Cons

  • Heavier than traditional still photography lenses
  • Requires professional matte box and support gear
  • Fixed prime focal length lacks zoom versatility

Setup, Compatibility & Care

Mount the lens to your Sony E-mount camera body, ensuring the mount is fully clicked and locked. Given the lens's weight, it is highly recommended to use a lens support baseplate to protect the camera's mount from stress. For maintenance, store the lens in a humidity-controlled environment. Clean the front element using an approved lens cleaning solution and a microfiber cloth. Ensure the 82mm filter thread or the 95mm front barrel is clear of debris before attaching filters or matte boxes to avoid cross-threading or mechanical resistance.
