Review on Ultra Wide Angle Zoom Lens for SLR Cameras - Canon EF 17-40mm f/4L USM by Aashit Seth ᠌

Gorgeous glass with an amazing picture. I didn’t shoot on a full frame, but on my 400D this lens has been used as a staffer for almost a year now. Didn't let me down once. It is guided easily and quickly, misfires at least. When shooting in cramped studios, it easily allows you to remove the "size" (although you have to take into account the fact of wide-angle). Overall rating - solid 5
