Excerpt: I shoot a T3i size C sensor and my canon 55-250 just wasn't doing the job reaching out to wildlife. I was told by BH that the Canon 70-300 f4-5.6 IS USM lens would be around a 480mm on a crop sensor camera. That's not true. I received my lens today and ran out to see how closer I could get to things and noticed it seemed just like my 55-250. I shot a few comparison shots and low and behold the 70-300 is only 50mm longer than the 55-250.
Conclusion: This lens works well for shots that are close. Zoomed all the way out nothing is sharp. It's not much good for long distance bird shots. I also think it is a bit slow on the auto focus which I could live with if the pictures were sharp. Mostly a costly disappointment.
Conclusion: This lense will not focus when zoomed at 300mm. Most pictures are blurry. I have an efs 55mm to 250 mm that blows the socks off of this one and costed half as much. I expected more from Canon than what i got.
Excerpt: I bought this lens in Jan '09 when I first got all my camera gear. It has served well, very sturdy and nothing wrong with it to this day. My photography interest is more for macro but I'm now getting into the birds and using it more and more, but it's simply not good enough. The autofocus is pretty jittery and sometimes has trouble locking on - especially if there is a small branch or something near the autofocus point.
Pros: Durable, Lightweight, Rugged, Strong Construction
Excerpt: Main use if for bird photos @300mm<br />Main advantage, is that it is light, relatively small & inexpensive. A good walk-around lens.<br />Unless my copy is out-of-cal,for my use at 300mm it is disappointing, with no resolution details. For decent photos, I revert to my 400mm 5.6, and bear the extra weight.
Excerpt: Like many, I exhaustingly researched this lens vs. the F4 L before ignoring the smattering of poor reviews and getting the 70-300. Washed out color, soft images and found the focus to hunt when you need it to lock-up quickly. I attributed this, in part, to human error and struggled to make this lens work for me. It never did. The IS is o.k., but you need to use support anyway because of the lens speed.
Excerpt: Read few genearly positive reviews here before renting this lense for a weekend. What a disapointment! The only usable range where image is still somewhat sharp is around 70-100mmm. Colors are dull. And of coure, it is DARK. I am speaking not only about aperture which can be seen from specs, but overall quality of optics being used.

Summary: Purchased this lens with Canon eos 20-d, found to be overall soft, 200+ images all sole ft. Contacted Canon TS, was informed there currently is an unresolved focusing issue with this lens. Placed on a recall list when solution is discoved will be notified to return for adjustments. Unacceptable product.....
Summary: A very disappointing purchase. I could not achieve sharp focus photographs with it. It was so soft-focus that I traded it in afterwards, incurring a loss of most of its value. I have never traded-in a lens, so soon after buying it, ever before.
