Excellent walk around lens for those that dont' go the 'L' glass route. Great flexible focal range, and takes nice shots. It's on my camera most of the time. I did have an opportunity to take some shots with an L glass lens and compare it with this lens, and there was not a huge difference, but then...

Fast / accurate auto-focus; Nice Bokeh; Consistent Output; good focal range

Slightly loose end barrel

It is my go to lens that I keep on the camera all the time. Great for close up shot but will zoom in great for the shot across the way as well. The only drawback in my opinion is it is a heavy lens but I think it has to do with the great construction of the lens (not a cheap plastic lens in anyway).

There's a lot packed into this compact lens, starting with a generous 4.8x zoom range that covers the entire gamut of frequently-used focal lengths for full-frame photography.

Great all-rounder

Cheeky "macro" designation

This is the best walkaround/travel lens for fullframe users. I prefer this than the more expensive 24-105L. Yes, the L-series will give you (slightly) better results, but for more money and weight (duh). I love this lens because of the portability.

The AF mechanism is internal and employs an efficient (USM) that leaves the focusing ring undisturbed in automatic mode but with the option of full-time manual focusing intervention if this is required.

I own a Canon Rebel XTi an entry-level SLR and I purchased this lens hoping I can use it as an all around lens, but I quickly realized this is probably not going to be so. If you, like me, own a half-frame camera, you will probably want to consider getting an additional lens to cover the wide-angle...

I am stunned at the image quality this lens has produced for me. Action shots are crystal clear thanks to IS which is extremely quiet compared to my other Canon lenses. And indoor shots without a flash are a breeze, thanks to the 3.5 aperture and IS.

IS; USM; PERFECT FOR EVERY DAY USE; GREAT PICTURES INDOORS AND OUT

NOT WIDE ENOUGH FOR WIDE ANGLE SHOTS ON 1.6 DIGITAL CAMERAS

Though not the image quality desired for PRO use, this lens is very capable for the hobbyist. Close work with average to good lighting has resulted in some clear quality images with my Canon 40D. I was not as pleased with the far range as the focus seems soft.

Consistent Output; Easily Interchangeable; Good amature lens; Lightweight; Quick Focus

Not weatherdust sealed; Soft focus at far range

lens works realy well, as it should simple operation easy to clean and great photos . a really good lens for the price another quality canon product
