The Canon EF 16-35mm F2.8L III USM has been long awaited by many professional photographers and exceeds expectations. It’s better built than its predecessor and gives astounding sharpness over the entire image, even at its full opening of F2.8. At 16mm it actually outperforms many ultra-wide-angle prime lenses. Distortion is low, while the anti-reflective coating very effectively reduces ghosting and flare. The Canon EF 16-35mm F2.8L III USM is built for everyday professional use and delivers an image quality that will satisfy even the most demanding users.
