The Expander increases the diameter of the image circle by 1.6x on Super35 PL prime and zoom lenses. This allows for a greater variety of lens choices when filming with cameras like the RED Dragon that has a 46.31mm (8K) diagonal sensor.
Tokina engineers gave special attention to the 7-element optical design to ensure the integrity of the original lens’ performance and to keep light fall off to a manageable 1.36 stops. The all-mechanical design is robust, durable, and lightweight. The Tokina 1.6x Expander performs best when used with lenses that have a T2.0 or larger aperture and when the lens is stopped down to T2.8 or smaller.

- Compatible with 6K-8K cameras with image sensors up to 1.85″
- Designed with seven elements in four groups, enabling an aperture compensation of just 1.36 T-stops
- Performs best when used with lenses with a T2.0 or larger aperture and when stopped down to T2.8 or less
