This lens is Fantastic,has a fast autofocus because of the f2.8, i had the 70-200mm f4, which was super fast but this one performs much better. The built quality is fantastic, i would recommend this lens to all canon eos users who want to put Telefoto on their bags, wow!
Pros: Fast auto-focus, Superior build quality, sharp images
Cons: lens hood design
This is the second of this lens I've owned. Personally I find while the IS version may be sharper in places, the non-IS is sharper overall throughout the zoom range. I sold my original to upgrade to the IS and wasn't pleased with sharpness, so sold it and purchased another non-IS and am much more happy with it. Typical L build quality, solid feel, fast and quiet AF and quite durable. My only complaint is the design of the lens hood attachment, a problem I have with most of my L glass - after a while they get loose and won't stay put, but I know I'm tougher on equipment than the average or casual shooter.
Pros: Fast auto-focus, Superior build quality, sharp images, excellent image quality with nice bokeh
Cons: expensive, heavy
I sold mine and bought EF 200mm f2.8 prime. It was too heavy for me to carry around. Normally needs a tripod when you shoot at 200mm. That's the same as the prime but the prime is much lighter. IQ is excellent. As far as sharpness you might get almost same result with 70-300mm f4-5.6 IS, but this one has very nice bokeh. AF is fast and quiet. L quality built. But if you can find a good used IS version for a similar price, you might want that instead of this.
