I have had this lens for about a month now and used it quite a lot, I am taking photos almost every day. I also had the previous version of this lens which was OK but didn't get that much use.

For 90% of my photos this will replace my 18-55 and my 55-250 lenses

Works fine as expected.

very good lens, very sharp and smooth ,great carry around lens, leave it on my canon 500d always unless want the 55-250is for distance.

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.
