This unique lens offers both circular and full-frame fisheye effects, making it an excellent choice for creative photography and videography. As part of Canon's professional L-series, the lens features robust construction, advanced optics, and a fast, silent autofocus system, making it suitable for a wide range of shooting scenarios, from landscapes and architecture to artistic and experimental photography.

Key Features

Versatile Fisheye Zoom Range

• 8-15mm Focal Length: Provides a wide range of ultra-wide-angle perspectives, from a full circular fisheye at 8mm on full-frame cameras to a full-frame fisheye effect at 15mm. This flexibility makes it ideal for capturing immersive, distorted images that emphasize the curvature of the lens.
• Constant f/4 Aperture: The lens maintains a constant maximum aperture of f/4 throughout the zoom range, providing consistent exposure and depth of field control.

Professional L-Series Optics

• Superior Optical Quality: The lens is constructed with 14 elements in 11 groups, including one Ultra-low Dispersion (UD) element and one aspherical element. These elements work together to minimize chromatic aberrations, distortions, and other optical imperfections, ensuring sharp, high-contrast images across the frame.
• SubWavelength Coating (SWC): Reduces flare and ghosting, even in challenging lighting conditions, providing better contrast and color fidelity.

High-Speed Autofocus

• Ultrasonic Motor (USM): The ring-type Ultrasonic Motor ensures fast, accurate, and nearly silent autofocus, making it suitable for both still photography and video recording. Full-time manual focus override is also available, allowing for precise adjustments without switching out of autofocus mode.

Robust Build Quality

• L-Series Durability: As part of Canon's prestigious L-series, the lens features a rugged construction designed to withstand the rigors of professional use. It includes weather sealing to protect against dust and moisture, ensuring reliable performance in challenging environments.
• Fluorine Coating: The front and rear elements feature a fluorine coating that repels water and oil, making the lens easier to clean and maintain.
