I bought this lens to go with a Canon camera body, as it is more versatile than the standard lens. It was a little bit heavier than I expected, but this actually gives it a feeling of being robust and you soon get used to the weight.

Clear instructions; Rugged; Nice Features and Settings; Great Resolution; Easy To Use

Heavier than expected

I use this lens for portraits in interior spaces. Focus is sharp and stable. I am able to use this in low light and still get great results. I love the range and its not too heavy to keep with me at all times.

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

I shoot landscape, animal and grandkids with this lens. It is easy to focus, takes very clear pictures and gives the extra power needed for the photos taken within 30ft.

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

The Canon EF 28-135 mm f/3.5-5.6 IS USM is a standard zoom lens. The optical system in the lens uses glass-mold aspherical lenses and has lens construction of 16 elements in 12 groups.

If you are on a budget, but want an overall good lens that will give you sharp pictures for the price, then this is the lens to buy. If you can only purchase one lens go with one with image stabilization (IS) you will be happier and have fewer blurry pictures.

Wide range of zoom positions and has IS

Not great for low light pictures

I shoot video professionally with my 5D Mlll. This lens is light and good for personal travel. If it got beat up or dinged its not a heartbreak.

I believe you have to look for a good copy. Love the range on the 1.6 crop. Very seldom do I have to switch out lenses for a wedding, except of course wide angle and low light.

Sharp; IS works well; good walk around lens for the money

A little light fall off; Zoom loose after heavy use

This is a good starter lens that allows the user to get used to using their camera with little to worry about with the lens. It has good resolution even at the extremes of the zooming.

Have owned two of them since 2001. I have used them within my photo studio for all types of images from commercial, wedding and portrait since 2001 on full frame and crop sensor digitzal EOS bodies as well as Rebel XSI bodies.
