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.
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.
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.
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.
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.
Pros: Good build quality, Good optical performance, not too big.
Cons: Auto focus is poor from 200mm to 300mm zoom.
Excerpt: I brought this lens primarily for shooting video and this is what my review will reflect. Overall a Good Lens - but poor in Low Light. The 4.5 F-Stop means needing to crank the ISO up (and add noise) when a lens at 2.8 could shoot fine.
Pros: Durable, Easily Interchangeable, Fast / accurate auto-focus, Lightweight, Strong Construction
Excerpt: This is an ok lens. It has a good zoom range and the image quality is OK. Personally I would not buy it again. Images were not as sharp as I would like. Shooting at 300mm soft...Shooting at 70mm was soft. The sweet spot on this lens is 100 to 125mm at f/7.1 to f/9.0.
