Optical Performance
Canon designed this lens with high-quality elements to deliver sharp and accurate images.
Color and Clarity: Two ultra-low dispersion elements reduce chromatic aberrations and color fringing. This improves clarity and ensures accurate colors.
Sharpness and Distortion Control: Two aspherical elements minimize spherical aberrations and distortion, giving more precise rendering.
Better Contrast: A Super Spectra coating reduces flare and ghosting, enhancing contrast and color neutrality, even in strong lighting.
Autofocus and Stabilization
The lens balances optical quality with excellent focusing and stabilization features.
Fast and Accurate AF: A ring-type Ultrasonic Motor (USM), internal focusing system, and high-speed CPU deliver quick, quiet, and precise autofocus.
Manual Override: Full-time manual focus lets you make fine adjustments without switching modes.
Stable Images: The built-in Image Stabilizer compensates for up to four stops of camera shake, making handheld shooting easier in low light.
