One of the best lenses i ever bought. Canon EF 17-40mm F/4 L USM Lens is a wide-angle lens designed for Canon cameras. It belongs to the Canon EF "L" series, (professional standard lens) featuring a maximum aperture of f/4. This lens allows both auto and manual focus, with a focal length range of 17-40mm. It comes with a 77mm compatible filter size and front lens. I've had the lens from knew, it's in excellent condition but is used and the lens cap has signs of wear as shown in pictures. I'm only selling as it upgraded my camera and this lens is not compatible. The pictures of landscapes are two examples of pictures I've taken with this lens. if you have any questions please feel free to ask.
