Optical Performance

Canon designed this lens with advanced optics to deliver sharp and vibrant results.

• Color and Clarity: Two ultra-low dispersion elements reduce chromatic aberrations and color fringing, resulting in high clarity and accurate colors.

• Improved Contrast: A Sub Wavelength Coating controls flare and ghosting, which enhances contrast in strong or direct lighting.

• Fisheye Flexibility: The zoom range lets you switch between a circular fisheye look and a full-frame rectangular fisheye effect, both producing dramatic results.

Autofocus and Handling

This lens balances its creative optics with reliable performance.

• A ring-type Ultrasonic Motor (USM) ensures fast, quiet, and precise autofocus.

• Optimized focusing algorithms and a high-speed CPU further enhance accuracy.

• You can also use full-time manual focus override for fine adjustments without switching modes.

Durability and Build Quality

As part of the L-series, the 8-15mm f/4 is built for professionals who work in tough environments.

• Weather-Sealed: Dust- and moisture-resistant construction allows use in challenging conditions.

• Fluorine Coating: The front bulbous element resists smudges and fingerprints, making cleaning easier.

• Filter Options: A built-in rear filter holder accepts cut gel filters for additional creative control.

Compatibility

• Full-Frame Cameras: Designed for Canon EF-mount DSLRs with full-frame sensors.

• APS-C Cameras: Also compatible, offering a 12.8–24mm equivalent focal length range.

• Constant Aperture: The f/4 maximum aperture ensures consistent brightness across the zoom range.
