The Tokina Cinema 1.6x Expander increases the image circle of Super35 PL prime and zoom lenses by 1.6x. It enables cinematographers to use their Super35 PL lenses on modern full-frame 6K and 8K cameras. For example, it supports cameras like the RED Dragon with a 46.31mm (8K) diagonal sensor.
The Expander enlarges the projected image circle so Super35 PL lenses cover larger, full-frame sensors. As a result, you gain a greater variety of lens choices when shooting on full-frame cinema cameras that require a larger image circle.
Tokina designed the Expander with a seven-element optical layout arranged in four groups. This configuration preserves the original lens performance while keeping light falloff to a manageable level. Additionally, the Expander uses an all-mechanical construction that is robust, durable, and lightweight.
For best results, use the Expander with lenses that have a T2.0 or larger aperture. Also, performance improves when the attached lens is stopped down to T2.8 or smaller. These operating conditions help maintain image quality and control light falloff when adapting Super35 lenses to full-frame sensors.

Use the Tokina 1.6x Expander when you want to broaden lens options on full-frame cinema cameras. It is especially useful if you already own high-quality Super35 PL primes or zooms and need to shoot on cameras with larger sensors such as certain 6K/8K models.
Question: Will this let me use Super35 PL lenses on full-frame 6K/8K cameras?
Answer: Yes. The Expander increases the image circle by 1.6x, which enables many Super35 PL lenses to cover full-frame sensors used in 6K and 8K cameras, including cameras with a 46.31mm diagonal sensor like the RED Dragon.
Question: How much light do I lose when I use the Expander?
Answer: The optical design provides an aperture compensation of approximately 1.36 T-stops. For practical shooting, Tokina recommends starting with lenses that are T2.0 or faster and stopping them down to about T2.8 or smaller for optimal results.
Question: Is the Expander electronic or mechanical?
Answer: The Expander is an all-mechanical device. It features a robust and durable construction while remaining lightweight, so you can rely on its physical build without electronic components.
Question: Which sensors and cameras is this compatible with?
Answer: The Expander is compatible with cameras that have image sensors up to 1.85". It is intended for use with full-frame 6K and 8K PL-mount cameras and works well with systems that require a larger image circle.
