Title: Worst useless lens
Review: After using this lens with other lens, I conclude thatthis is the worst lens I have ever used so far.And it is useless for crop sensor cameras. And I am wonderingwhy this lens came with Canon 7D as a bundle.Whenever I bring this lens out, I always regret.28mm is not wide enough. And the general purpose quality of28-135 mm is below the general quality.If I compare this lens with Sigma 17-70mm, Sigma is so muchbetter. Sigma has so much quality and the sharpness is reallyamazing. I normally don't realize it until I switch the lens withthis low quality Canon 28-135mm. Comparing with Tamron's18-250mm, within the same range, I think that Tamron isstill better. And I am wondering why you should use this lenswhen you use cropped sensor camera.And I you use an expensive full frame camera, there is noreason why you make your full frame camera a cheap point andshoot by using this lens.
