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

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.

The Canon 28-135mm f/3.5-5.6 lens with Image Stabilization is a very capable, and more importantly, affordable lens,and is perfect for times when you just want to have one lens on the camera but you also want to have a lot of options with your focal range. While you get the benefits of a slight wide to telephoto range in one handy package, you do lose in light stops as you move through the focal range (the maximum aperture stops down as you move toward the telephoto end of the range). This is where the image stabilization comes in very handy, and allows you to keep hand shake at bay even when you have to compromise on shutter speed to get the correct exposure.

I've had no complaints about the optical quality, I think you'll be pleased with the shots you get from it - the lens may be cheap but don't confuse that with what the quality of image this lens can provide. Keep in mind on a camera with a cropped sensor (any Canon DSLR model other than the 5D and 1D models) the focal range is equivalent to @45-215mm - you lose a bit of the wide angle advantage, but you get more telephoto, so it depends which end of the focal range you value the most as to whether that is a disadvantage or not.

This lens is an excellent general use lens for either a digital crop (Rebel, 40D, 50D etc) or full frame camera (5D, 5D MKII) although its slightly less appealing on a crop camera as the zoom range isn't quite as wide as on the full frame but still very respectable.

I actually got this lens to upgrade my original lens from the XTi set (which I was able to sell on Craigslist). It was a good upgrade, the zoom was better up to 135mm and the IS is good for picture taking. It is a versatile lens to use on a daily basis. Sometimes when I need to I use my 50mm prime for portraits but most of the time I have this on.

Plasticity body but does feel solid, would have liked it to have more metal on it for $400. There is zoom creep when pointing extemely up or down especially when filters and hood are on. (does not come with a hood - again for $400 really should be part of the package).

Main objective is the picture quality which is very good. Sharp and well saturated with good contrast. I also like the fine focus adjustment ring - nice.

I think this was a good upgrade for the XTi, I do like using it and think it is a fair price when considering other options. For an extra 1 star should come with a hood and have no zoom creep and perhaps a bit more metal in the outer construction. One of the better non L lens.
