Principal Features
Resolving power that overturns the conventional wisdom about fisheye lenses
The latest optical design thoroughly corrects each type of aberration. This lens has the unique expressiveness of a fisheye lens and high resolution throughout the entire image from a wide-open aperture.
- Even wide-open, high resolution and point image reproducibility across the entire image The lens consists of 21 elements in 15 groups, including 4 FLD glass elements, 3 SLD glass elements, and 2 aspherical lens elements. By correcting sagittal coma flare and other aberrations, the lens can precisely reproduce bright points of light across the whole frame even wide open, making it ideal for astrophotography.
- Various shooting assist functions
- Dust and splash resistant structure and water and oil repellent coating
- Adopts a linear motor HLA
- Excellent build quality
- Diagonal fisheye lens with 180° angle of view The powerful distortion effect allows users to enjoy expressions such as a unique perspective and emphasis on the subject at a 180° angle of view. The unique descriptive power of this new fisheye lens, which combines an incredible 180° angle-of-view with very high resolution optics, delivers a level of artistic potential that exceeds other fisheye lenses.
- Designed to minimize flare and ghosting The lens is designed to handle all conditions of incident light based on state-of-the-art simulation technology. High backlight resistance enables clear and sharp images under any lighting conditions.
A wealth of latest functions and excellent build quality
The lens is equipped with various functions to assist shooting, including an AFL button* to which preferred function can be assigned and an aperture ring, and uses a linear motor HLA（High-response Linear Actuator） as the AF actuator to enable fast, quiet, and highly accurate AF shooting. The lens also ensures a high level of weather resistance and robustness, as well as excellent build quality that allows for long and reliable use in any environment.
- Function available on supported cameras only.
- The structure is designed to be dust and splash resistant, but not waterproof. Be careful not to bring the lens in contact with a large amount of water. Water inside the lens may cause major damage and even render the lens unrepairable.
