A canon lens hood can be purchased online from Amazon. Overstock, Sears and HSN are three other sites that sell this type of hood. It is best to shop around to get the best price.

This is for when you use adjustable filters such graduated or variable ND on the front of your lens. The removable section allows you to rotate the filter while the hood is still attached.

Some of the best lens hoods, based on amount of sales, include the Canon EW-73B Lens Hood, Fotodiox Dedicated Lens Hood, 52mm Hard Tulip Lens Hood for Nikon and the A&R Brand Professional 58mm Lens Hood.

open the hood, take off the black plastic piece where the hood latches down. just pop out the pins. then you'll need a flat blade screwdriver and stick it in a hole in between the headlight and the lens.. there is a small piece needed to be pushed in. while that piece is pushed in, the lens and headlight should come apart...then they are now released.

Open the hood it pops into the backside of the lens.
