To be updated nowadays is a hard work, every day a better gear is available, and I can't stay behind. Today I got two of the newest lens from Canon, the EF 11-24mm f/4L USM ultra wide-angle zoom lens, with the widest angle of view (126º05’ diagonal) ever achieved for a rectilinear full-frame Digital SLR lens and the new Canon 16-35mm f4L ultra wide-angle zoom lens features newly developed, high quality Canon optics that incorporate three GMo (Glass-Molded) aspheric lens elements, including a large-diameter aspheric lens, which help improve image quality by correcting aberrations.
