Very versatile, the quality of this lens is superb, giving me clean, clear shots under all lighting conditions in the field...in any terrain, and from most angles. The range (18-135mm) enables me to easily frame the old barns and sheds I photographin the way I want to frame them.

Consistent Output; Easily Interchangeable; Fast / accurate auto-focus; Lightweight

I've been using an EF-S 18-55mm F3.5-5.6 lens on my old Rebel, which was the crappy one that came with the camera, forever. It's taken me years to decide on a general purpose lens that would take the place of the one I'm employing.

Canon EF-S 18-135 IS STM is a great walk around lens. Why? It has a nice range - from wide to mid-tele. It is an excellent for those times when you don't want to be bothered with changing the lenses (for example during vacations). I can put it on, and leave everything else at home.

I read the reviews and thought I'd take a chance. You certainly get what you pay for. I won't ever use this lens and now I need to save up for a real lens before I can make money with my camera. Disappointment does not begin to describe my feelings.

Easily Interchangeable; Consistent Output; Durable

Only for baby pics; Lens Creep; Poor in Low Light

This lens basically lives on my Canon C100. It has a great zoom range, it's lightweight, compact, and sharp. With the addition of the PZ-E1 Power Zoom Adapter, it operates much like an ENG lens, capable of smooth zoom shots.

I'm a casual amateur photographer. I photograph my children, landscapes and animals. The lens is a bit expensive, but it gives me greater range than the kit lens which I need for even casual photography. The lens is light and easy to use.

Consistent Output; Lightweight

Good for those in the next level. Good picture quality

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.

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 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.
