Pros: Fast
Cons:
Poor build/quality control by Canon

I have had a very disappointing experience with this lens. I have been a Canon user since the 1970s beginning with the FTBn and I have several L series lens, all of which work flawless. I ordered it from Dell and as soon as received it I took several test shots with my 40D at various focal lengths using autofocus. I was surprised to find none of them were sharp. I then put the lens on both an XTI and an old Digital Rebel and got the same results. I called Dell and they sent a replacement, taking two weeks as they had none in stock. I was shocked to find the same problem with the replacement lens. I then decided to put the lens on a tripod and take some shots of the fine print on a small bottle at a distance of about five feet. I first to a shot with autfocus on and the switched it off and move the focus ring slightly to the right taking 3 shots and the reset autofocus and then took three shots while turning the focus ring in small increments to the left. When I looked at the shots on the PC I found the autofocus shot very blurry, but the shot I took in manual focus turned just slightly to the left from the autofocus point it was considerably sharper. I have sent the replacement lens to the Canon repair facility in New Jersey and hope they are able to fix it. What I can understand is how two lens, with non-sequential serial numbers, have a common defect. I can only assume that Canon is having a problem with quality control. I hope Canon recognizes they have a problem and takes corrective action. As I said, I am a long time Canon user but this kind of problem makes Nikon look better and better.

Pros: None yet, have not received a good copy.
Cons:
Poor quality control

After many long hours of deliberation I finally took the advice of many of you here in this forum and ordered this lens. I purchased it from Dell, whom I have always had good service from in the past. I paid for next day shipping. Unfortunately they chose DHL to deliver it. After misrouting the package and 6 days later then lens arrived. Anxious to get the last few minutes of sunlight I quickly mounted it to my 40D and took a few shots off the back patio. When I loaded them on the PC I was amazed, but not for a good reason. Every photo seemed a little out of focus. I then took some indoor flash shots and got the same result. I then took several comparison photos using an old 18-55mm (non IS) lens that came with my old Rebel. It was hard to believe but in every case the shot taken with the cheap 18-55 lens was noticeably sharper. I called Dell and of course got an RMA. Of course they will send a replacement lens and the paperwork to return the defective one, but it takes up to 8 days to process the paperwork and then they said they ship it overnight. I just hope its not DHL again. I caution anyone buying this or any other Canon to make sure to get it from a reliable with a good reputation for returns. It looks like Canon also needs to start doing a better job with quality control.
