Conclusion: Maybe it was my mistake but I had high expectations on this lens. I had the opportunity of taking the EF 400 F4 DO IS on a couple of air shows. The Diffractive Lens technology works great on this lens but its not the same with the 70-300. It is a light wight lens and that makes it nice for traveling and not being very flashy as the big white L's. But unfortunately it is not a very sharp lens. Not hapy with it.
Excerpt: Superb build quality. It is nearly identical in size to the 24-105 F4l. Solidly built. The interest in this lens is the 300mm reach in a greatly shortened barrel length. It does not broadcast your presence the way a 70-200 tube does. Good for street shooting. <br /><br />Disappointing results. The zoom ring was very difficult to twist to lengthen and the movement was not smooth. Prevented easy zoom to length if you have the camera to your eye.
Conclusion: If you really need a small and lightweight lens, this is probably the best one you'll find. The rapid focus, small size, and solid IS is nothing short of amazing. I've successfully taken some pictures handheld at night and bumping around in crowds. On the downside, the images are hazy. A large diameter unsharp-mask and black level adjustment are needed in post processing, which about doubles the noise level.
Conclusion: I bought this lens a couple of years ago and have used it significantly while traveling. It is a nice lens, relatively light for the range and convenient in size. Pictures lack the sharpness that i was expecting from an expensive lens. in my case I don't think the convenience in size compensates for the average quality of the images in the far end of the range.
Conclusion: Never could get a decent photo out of this lens, photos always slightly out of focus, couldn't handle high light conditions at all. NOT the all around lens I expected. Replaced it with the 38-300 L lens.
Summary: The lens produces good pictures but there is one very notable problem. When zoomed from 200mm to 300mm the autofocus is not at all accurate. This is serious enough that I will not use AF when zoomed in this range. I get very nice, sharp pictures even at 300mm but only with manual focus. I have verified the problem is with the lens and not with my 40D camera. MF is tedious and takes time so you will miss some shots when zoomed out.
Pros: Good build quality, Good optical performance, not too big.
Cons: Auto focus is poor from 200mm to 300mm zoom.
Excellent results for size and weight, but zoom is a problem

Summary: This lens gives good results except for two weaknesses. First, the diffractive optics causes little "donut" hot spots in images when areas are exceptionally bright i.e. reflection off a lake. They look a bit like the donuts of a telephoto mirror lens. Second, the zoom ring is very hard to turn. It doesn't have the fluid smoothness of their other zoom lenses. It's acceptable in use, but barely.
