The large-diameter RF mount and short back focus design makes this a balanced, comfortable and easy-to-use lens in many lighting situations, delivering detailed images at various focal lengths.

Three aspheric lenses deliver high image quality from center to corner, while three UD lenses help reduce aberrations, delivering sharp images with reduced distortion throughout the image plane.

Regardless of focal length or angle of light, Canon's Air Sphere Coating (ASC) significantly reduces lens flare and ghosting for clean results with minimal distractions and aberrations.

Fluorine coatings on the front and rearmost surfaces help prevent dirt and dust from sticking to the lens, making it easy to clean smudges and fingerprints off.

Dust- and weather-resistance in the lens mount, switch panel and all rings allow reliable performance even in difficult weather. The applied sealing helps keep water and dust from entering the lens.

Rugged and precise, this robust lens can endure the rigors of professional use. L-series level vibration shock resistance in the lens barrel helps maintain focus and settings in turbulent situations.
