♦ 1) Canon EW-83E Lens Hood for Canon EF 16-35mm f/2.8L USM, EF 17-40mm f/4L USM & EF-S 10-22mm f/3.5-4.5 USM Lenses

The Canon EW-83E Lens Hood is primarily designed to prevent unwanted stray light from entering the lens by extending and shading the end of the lens. In addition, since the end of the lens is extended, you also get the added benefit of some extra protection from accidental impact. Dedicated lens hoods, such as the Canon EW-83E, are designed to match the specific focal length of the lens it was designed for.

This Vivitar UV Filter is a multi-purpose, fine-weather filter that is designed to optimize your photography experience. UV filters block out unwanted ultraviolet light and prevents the UV "fogging/haze" effect", which can result in inaccurate color and lower the apparent sharpness. This filter is also ideal for protecting your valuable lens from scratches and dust, and it can be kept on the lens at all times. Perfect for digital, video and photo.

The CapKeeper 2 is an elastic loop, which wraps around lens barrel of your camera, with lens cap leash. It prevents lens cap loss with adhesive-backed disc attached to the cap. The CapKeeper 2 is designed for SLR cameras with interchangeable lenses and video cameras. Never lose your cap again!

This 6-piece cleaning kit contains everything you'll ever need to properly clean your lenses, including a Hurricane Air Blower, Lens Cleaning Tissues, Lens Cloth, Lens Cleaning Liquid, Brush and Cotton Swabs.

I wanted a lens hood and filter for a new lens that I bought. After checking the price of the hood and lens separately I found, purchasing the entire kit was cheaper than buying separate pieces. I worked out fine.
-- lens hood and filter

I like this lens in general. But frankly I was hoping for something more powerful. Maybe I should have bought a fish-eye. The wide angle is OK, but not as wide as I like. Still a very good quality lens by Canon. -- Good, but hoped for better.

Needed a lens hood and felt that this was a great deal with lots of stuff for the money! -- Great assortment of stuff
