The Sigma Lens 150-600mm F5-6.3 DG OS HSM Contemporary for Canon is a high-quality telephoto lens suitable for Canon cameras. With a maximum aperture of f/5, it allows for excellent low-light performance and shallow depth of field. This lens is part of Sigma's Contemporary series, known for its exceptional image quality and build. It has scratches on the front of lens, reason for cheaper selling. it works perfectly and has no issues with the image quality and no markings show up on the ending photographs as u can see with my pictures also posted. it comes with the tripod attachment, lens cap, wildlife camouflage lens and camera cover inside the Sigma Lens bag.
