Combining a constant f/2.8 aperture with 5-stop image stabilization and a compact 1066g build, this is Canon’s lightest and shortest 70-200mm yet. Its optical formula, featuring one Super UD element and two aspherical elements, delivers sharp results with minimal aberrations across the full-frame image circle. This lens is best for landscape and wildlife photographers who need a portable, weather-sealed telephoto zoom for travel.
