Canon EF 17-40mm f/4L USM Ultra Wide Angle Zoom Lens for Canon SLR Cameras

This lens is amazingly sharp and well-built. As a wedding photographer, I would highly recommend it. It is gorgeously wide, especially on a full-frame body like the 5D. Buy this lens!

Even 2 years ago the 17-40 L Canon lens was reserved for professional photographers because of its high price. Now it became available also for amatours. It's an amazing lens. Any picture taken with it its just fantastic. The colors, the sharpness, the quality its just beyond other lenses. "L" form canon holds its quality. I highly reccomend this lens for all photographers for whom taking pictures is more than just a hobby. IT'S DEFINITELY WORTH ITS PRICE!!!

This lens seems sharp at all distances and apertures. We are very pleased with it.

No plastic grinding against plastic when you focus this thing. Feels just like my Fujinon lens I use on my TV news camera. Pro gear. Want some? Pay up.

I bought this with my Canon 30D. This is a great lens and L series is the best. I have mostly L lens because the quality is worth the money.
