- It features 22 glass elements in 17 groups, including two Super ED and two ED lens elements, to minimize aberrations.
- The focus ring offers a full 200 degrees of rotation, allowing for precise and subtle focus adjustments during filming.
- All operation rings share a gear pitch of 0.8M, ensuring compatibility with standard follow focus and cine accessories.
- This lens suppresses focus shift while zooming, eliminating the need for re-focusing after adjusting focal length.
👎 Cons
- The 85mm front diameter and 82mm filter thread mean existing filters or matte boxes may need to be compatible or require new purchases.
- While offering excellent optical quality, its specialized cine design might make it heavier or bulkier than typical still photography lenses.
- The T2.9 aperture, though constant, is not as fast as some prime lenses, which could be a consideration for extremely dark environments.
- The 200-degree focus rotation, while precise, can be slower for quick focus pulls compared to lenses with shorter throws.
- This lens is specifically for the Fujinon X Mount, limiting its direct use to Fujifilm X-series cameras without adapters.
