Taking that acclaimed prime as its starting point, this lens offers the same level of sharpness and image quality while adding the flexibility of a zoom, making it a well-rounded choice for indoor sports, events and theater, fashion, and other subjects that benefit from long reach, high speed, and fast autofocus.\u003c\/p\u003e\n\u003ch3 dir=\"ltr\" class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eDesigned for Professionals Who Need Speed at Distance\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThis lens is made for shooters who can't compromise on light-gathering ability even at extended focal lengths. It's one of the first full-frame RF zooms to pair a long telephoto range with a constant f\/2.8 aperture across that entire span, a combination normally reserved for prime lenses or specialized super-telephoto designs. It clearly targets professionals working in sports, motorsports, wildlife at moderate distances, red carpet, and other high-action, low-light arenas where every stop of light matters.\u003c\/p\u003e\n\u003ch3 dir=\"ltr\" class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eL-Series Optical Performance and Build\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe optical design comprises 23 elements in 18 groups, including one Fluorite element, four UD (Ultra-low Dispersion) elements, and one glass-molded aspherical element, working together to achieve a high degree of clarity and sharpness with virtually no distortion. Air Sphere Coating and Super Spectra Coating help reduce backlit flaring and ghosting, while as an L-series lens, it features the highest level of build quality, including weather-sealing and fluorine coatings on both the front and rear elements to guard against water and dust.\u003c\/p\u003e\n\u003ch3 dir=\"ltr\" class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eStabilization, Autofocus, and Teleconverter Compatibility\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eBuilt-in Optical Image Stabilization provides up to 5.5 stops of shake correction on its own, rising to 6.0 stops of Coordinated IS when paired with an EOS R-series camera featuring In-Body Image Stabilization. A Dual Nano USM autofocus system incorporates both a ring-type USM and an STM mechanism for fast, nearly silent focusing with full-time manual override, while a configurable control ring allows quick adjustment of aperture, ISO, or exposure compensation. The lens is fully compatible with Canon's RF 1.4x and 2x extenders across the entire zoom range, extending reach up to an effective 200-600mm f\/5.6 with the 2x extender.\u003c\/p\u003e\n\u003ch3 dir=\"ltr\" class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eKey Features at a Glance\u003c\/h3\u003e\n\u003cul dir=\"ltr\" class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3 print:block print:space-y-1\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eLens: Canon RF 100-300mm F2.8 L IS USM\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eMount: Canon RF (full-frame)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eFocal length: 100-300mm\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eMaximum aperture: constant f\/2.8\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eOptical design: 23 elements in 18 groups, including 1 Fluorite, 4 UD, and 1 aspherical element\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eAperture blades: 9-blade diaphragm\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eImage stabilization: up to 5.5 stops (up to 6.0 with coordinated IS)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eAutofocus: Dual Nano USM system\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBuild: L-series, weather-sealed, fluorine-coated front\/rear elements\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eMinimum focus distance: 1.8m, max magnification 0.16x\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eTeleconverter compatible: RF 1.4x and 2x extenders (full zoom range)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eDimensions: approx. 128mm diameter x 323mm length\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eWeight: approx. 2,650g (5.8 lb)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 dir=\"ltr\" class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eA Strong Choice for Professional Sports, Events, and Fashion\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe Canon RF 100-300mm F2.8 L IS USM is a smart choice for professionals and serious enthusiasts who need a constant f\/2.8 telephoto zoom with genuine reach and speed.
