Specialist Note: "The Sigma 10-20mm is a legendaryy lens for APS-C shooters. It was one of the first lenses to make true ultra-wide photography accessible without the extreme price tag of flagship first-party glass. The perspective at 10mm is absolutely immersive—it stretches the foreground and pulls the viewer into the image. Because the front element doesn't rotate during focusing, it is a dream for landscape photographers who use circular polarizers. It’s a sharp, reliable wide-angle that belongs in the bag of any creative travel or real estate photographer."

Condition Report: Good condition. The lens barrel shows normal signs of light use and minor surface character on the EX coating. The optics are clear, free from fungus, haze, or scratches. The autofocus is fast and quiet, and the zoom and focus rings operate smoothly. (S/N: 2269613)
