Canon EF 28-135mm f/3.5-5.6 IS USM Standard Zoom Lens for Canon SLR Cameras: Customer Reviews & Product Details

If you can't afford to buy L glass, this is the way to go. I debated for a long time between this one and 24-105L and finally decided to get the 28-135 instead. Mounted on my 40D, I get results that are very close to my prime lenses. Not as sharp, but close. I've yet to have problems with autofocus, even in dark room and the USM autofocus is great. The only downfall of this lens is the construction - the lens is a bit wobbly and the zoom creep is present if you point the lens down.

I've only recently gotten my Canon 40D and, as I said in the title, this lens came with it. So far, I am really happy with the detail it came capture.

I added an image of a Downy Woodpecker to the images area and the detail of the bird is very good. I'm still learning how to use my camera and lens, but so far, I am really happy. The picture was taken late in the afternoon, in the shade. I couldn't see the bird all that well. I had the 40D on auto and the lens all the way out (max mag). I used Picasa to lighten the pic and was really happy with what I ended up with. It sure didn't look that good in the tree.

I guess, when I get more proficient with the camera, I'll be able to take better photos, but with Picasa, I'll be okay.

I am really enjoying this lenses since I have received it about a month ago. Before this I was just using the standard kit lens that comes with a Rebel Xti (18-55). The glass in this lens seems to be superior to my prior lens and my images seems to have a crispness to them that they didn't have before. The only thing that I do not like about the lens is its ability to go out of focus. If you are on an upward or downward angle over 45 degree's the lens shifts out of focus. So I simply just hold it down manually, and that is a simple fix.

Once again I am super happy with my purchase and I would suggest this lens to anyone else because of its quality to price ratio.

I'll keep this short and simple.

Pros
-Great walk around lens(in the right conditions).
-IS is a plus
-Auto focus is OK
-Weight is not an issue.

Cons
-My copy pulled dust in. After a few trips to Utah/Arizona and a few hundred shots in less than hospitable conditions I did notice dust in it. This lens was great for a couple years, but time and the elements caught up with it.

Bottom line
-If you baby your equipment and don't plan on backpacking this is a great lens. If you plan on getting dirty, save up for one that's sealed.

Either it was damaged in shipping, or I got a defective lens. For whatever reason, the picture quality on any photo taken on this lens (with every setting, stop, is on/off, tested) came out blurry, particularly on the left side. Photos taken with my old stock 18-55 lens were dramatically clearer. The zoom range was decent, but I'm disappointed. Sending this lens back. It didn't even come with a manual. I was really looking forward to a lens upgrade.

Update -
I reordered the same lens from the same folks and, surprise, this one came in a real Canon lens box with manual and everything. Clearly the one I sent originally was not brand new. Be advised, if you don't get a manual and a canon box, you're getting sent something that someone else returned. That said, the new lens is beautiful. The shots are crisp and even using it for a few pictures, it's pretty awesome and the best lens I have.

If I could, I'd change my rating from 1 star to 4. For the hassle I went through returning the bad lens, I have to take away a star.
