Overview:

Advanced L-Series Optics

• Rectilinear optical design featuring one Super UD element, three standard UD elements, and three aspherical elements to reduce chromatic aberration and distortion throughout the zoom range, while also providing consistent edge-to-edge sharpness and illumination.
• ASC (Air Sphere Coating) and SWC (Sub wavelength Structure Coating) to reduce flare, ghosting, and other aberrations for increased contrast and colour accuracy.
• FLC fluorine coating applied to the lens's surface effectively repels dust, water droplets, grease, and dirt, ensuring easy removal even when they adhere to the lens surface. This coating also endures a high frequency of lens surface wiping, and its anti-reflective effect contributes to the capture of clear images.

Fast Auto focus and Image Stabilisation

• Fast and precise auto focus system delivering quick, nearly-silent auto focus performance with full-time manual focus override.
• Quiet high-speed STM leadscrew-type focus drive system that is especially beneficial to video users.
• An Optical Image Stabiliser minimises the appearance of camera shake by five stops to better enable working in low-light conditions and with slower shutter speeds. Additionally, when paired with an EOS R-series camera that has In-Body Image Stabilisation (IBIS), the Coordinated IS system allows for up to six stops of camera shake.
• Minimum focusing distance of just under 10" at all focal lengths for unique ultra-wide close ups.

Handling and Design

• Configurable Control Ring can be used to adjust a variety of exposure settings, including aperture, ISO, and exposure compensation.
• Nine-blade diaphragm to create a smooth and pleasing bokeh quality.
• Accepts rear insert-type gelatin filters, which are cut-to-size and inserted behind the rear lens element.
• Built-in petal-shaped lens hood.
• L-series construction sealed against dust and moisture for working in inclement environmental conditions.
