Excerpt: 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.
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. Disappointing results.
Excerpt: 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.
Excerpt: 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.
Excerpt: 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.
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.
Summary: Overall the Canon DO lens is okay and here is why. Using the lens on a T4i is akward because the lenses compactness and weight makes the feel in hand. The mainly plastic body of the T4i seems to be too light for the lens.
Summary: I really wanted to love this lens, but today sent it back for a refund. As others have noted, the lens is quite heavy, and the barrel creeps outward on its own. [Yes there is a locking switch to prevent this, but it only works when the lens is contracted.
