High-performance super telephoto lens. The EF 300mm f/2.8L IS II USM, with a wide f/2.8 aperture, is a powerful super telephoto lens that offers exceptional image quality with a sturdy and lightweight design. The professional L-series lenses are the flagship models in Canon's lineup and represent top-of-the-line EF precision optics. L-series lenses combine excellent performance with outstanding handling and are particularly resistant to dust and moisture.

The optical 4-stage image stabilizer is designed specifically for the lens' particular focal length range, counteracting camera shake that can occur during freehand shooting or at slow shutter speeds. Automatic pan detection ensures that the image stabilizer is effective even when tracking moving subjects. Since the image stabilizer is located in the lens, the corrected results are already visible in the viewfinder during image composition.

SubWavelength Coating (SWC) is Canon's patented coating designed specifically for the demands of digital photography. It minimizes flare and aperture reflections caused by reflections in the lens. The SWC coating minimizes the causes of reflections, resulting in clear and razor-sharp images. The new IS Mode 3 is perfect for all types of action photography, especially when camera panning is required, as it activates the image stabilizer only when needed.

Fast, precise, silent focusing is achieved with the ring-type USM (ultrasonic motor), providing incredibly fast and quiet automatic focusing. A fast CPU and optimized AF algorithms also contribute to high-performance focusing. The electronic manual focus can be used alternatively at any time without having to switch off the AF function.
