Excerpt: Easy to fit on and off and turn around for storing. Glad I spent the extra $ to get the Canon product as I travel a lot with my camera and am often putting on and reversing my hood for storage.
Excerpt: I heard a few reviews of third party hoods not fitting well so just went for the Canon hood for my 15-85. I don't regret my decision. It's definitely more expensive but fits perfectly and is built nicely. Would recommend this. One thing to note is that the hood will create a shadow if you use the internal flash (sometimes). Remember to remove it when you use internal flash.
Excerpt: Excellent quality & fit as you'd expect from Canon products. Expensive for what you get, but this isn't a cheap hobby. Works well to control flare outdoors. Side benefit is additional protection of the front of the lens.<br /><br />*Warning* - Hood will create shadows in image if used in conjunction with built-in flash at wide angles. Have not tested with external flash.
Pros: Durable, Easy To Use, Excellent Fit, Lightweight, Reliable
