A flagship super-telephoto zoom offering a constant f/2.8 aperture across an unusually long 100-300mm range, a first of its kind from Canon. Large, heavy, and expensive, it’s aimed squarely at professional sports and wildlife photographers who need prime-lens speed with zoom flexibility, and it pairs with Canon’s RF extenders to reach even longer effective focal lengths.
