100–300mm · f/2.8
The Canon RF 100-300mm F2.8L IS USM is a high-performance professional telephoto zoom with exceptional sharpness at f/2.8, even with extenders. It is relatively lightweight for its class at 2.65 kg, enabling handheld use, though it remains large and heavy for general use. The lens offers fast, silent autofocus and effective stabilization. However, it lacks a built-in extender and uses a 112mm filter thread, limiting filter options. It is best suited for sports, wildlife, and motorsport photographers who need a versatile f/2.8 zoom.
