Conclusion: This lens is a great travel lens. It works wonderfully with my 40d and 5d. While not the sharpest lens in my bag it is more than adequate for travel and snap shots. The image stabilization does it jobs and I can shoot hand held with out issue--I do bump up the ISO when necessary just because I like fast shutter speeds. I have not experienced the lens slippage mentioned so much in the other reviews.
Pros: Fast auto-focus, sharp enough when stopped down, excellent build quality, great travel lens
Conclusion: At first the lens challenged the areas that I wanted to shoot in. After a few minutes of toying with the lens and my settings in the camera I was able to learn to fully manipulate the lens to my advantage as well as my cameras advantage. The image quality in low light seemed to be an issue but proved to be user error and was easily overcome after a few shots and setting adjustments.
Pros: Fast auto-focus, Superior build quality, Super-sharp images, works great with my modified settings
Summary: The first copy that I bought of this lens was optically defective. The center and left side were sharp, but the right was soft even stopped down. I sold it. I checked out another sample at my local Photo Shop and that one (made in Taiwan) was uniform, but the edges were soft and dark. I told the sales person my story with this lens, so she took one off of a 7D kit. This one was sharp to the edges and had no falloff (made in Japan). I bought it.
Pros: IF you get a good sample, it is sharp and focuses quickly. Great range for full frame
Conclusion: I bought this EF 28-135mm last year as a general purpose lens for my 5D. it turned out to be a bad sample and the right side of the frame was soft, yet the center and left were sharp. I sold it and tried another one at a camera shop(made in Taiwan) this was uniform but the edges were low resolution and dark. The sales person took one off of a used 7D kit, this one was Made in Japan and it was much better (sharp right to the edges) and no falloff,I bought it.
Conclusion: My comment is specifically addressing an issue I have with the Canon 28-135mm lens with Image Stabilizer, AF/MF, and Macro functions. I have been a Professional Photographer for over 20 years and I am happy with the image quality in the photo's I've taken, however when taking pictures on even the slightest downward angle the barrel starts sliding causing the image to be out of focus.
Pros: Superior build quality, Super-sharp images, all of my camera equipment has always been canon
Cons: Poor build quality, barrel slide while trying to focus on subject
