Its optics are great, and it has unusually great handling. It is a very sturdy lens; almost the entire body is the zoom ring, and zooming and focus are a breeze. Close focus is only 1.5 feet (0.45 meters), so if you can see it, you can shoot it!

I broke my old 18 - 55mm lens and bought this one as a replacement due to being 18 a 135mm and not having to change lenses as often. It works well. It is much bigger and heavier though.

Camera lens auto focus broke within one week and you could hear grating/rattling from lens. Returned lens for replacement and I'm waiting for a new one to arrive soon. Worked great until it broke down though...

Easily Interchangeable; Fast / accurate auto-focus

My experience with Canon's lenses over the past 15 years have been nothing but excellence. And, they keep on improving their lenses, as well.

Light; Image Stabilizer(off or on); quick and responsive; FAST! Wide and Zoom

I purchased this lens with a 7D. I found it to be a great range, as I did not use the 10-24 a lot even while shooting scenery in Alaska for the summer. However, I am now faced with a large repair or replacement cost, as it does not focus smoothly and will change the zoom range when focusing.

I am an avid CANON user. Purchased the 60D and this lens came in the kit. Used it as much as a professional level user for over two years. The lens popped out a couple of months ago but I feel that I got every penny's worth of use from that lens.

This lens is a worthy alternative to the standard kit lens for your crop-sensor Canon SLR. The very flexible focal range and fast, accurate auto-focus make it a good option to stick on the front of your camera if you want to leave the rest of your kit at home for the day.

quick auto-focus; flexible focal range

not as sharp as some; poor manual focus ring

Bought the latest Canon 18-135 Nano USM lens to replace the original 18-55 on my 550D. Also wanted to be able to use the lens for video work with a power zoom. This lens fits the bill perfectly.

Amazing price through Pixmania and came with an unexpected lens hood
