The 24-105mm is Canon's latest version of the very versatile L-Series Full-Frame Lens.
The constant f/4 maximum aperture offers consistent performance and light transmission throughout the zoom range. Additionally, it has a rounded 10-blade aperture diaphragm for smooth out of focus elements.
Four glass-molded aspherical elements, including one large-diameter double-sided glass-molded lens, help to minimize distortions throughout the zoom range in order to maintain edge-to-edge sharpness and illumination.
An Air Sphere Coating (ASC) has been applied to lens elements to reduce backlit flaring and ghosting for maintained light transmission and high contrast in strong lighting conditions.
Finally, a ring-type Ultrasonic Motor (USM), along with an internal focusing system, high-speed CPU, and optimized AF algorithms, are employed to deliver fast, precise, and near-silent autofocus performance.
