Just to be clear, this is an entry level lens. The price was so good it was hard not to buy it. that being said. Design, just ok, as it is externally extended, so it lets air go in and out of the interior of the lens. Not good. it works well for the money. it is a decent lens. I use only L glass on my 5 d but I can still take a decent pic with this. it has all the "minor" problems you would expect with a lens in this price point. If you have 2500 buy the L glass, if you want a lens that works for under 100, this might keep you rolling for a while. Don't expect National Geographic to take notice though.
