    I purchased this lens to shoot soccer in bright light at outdoor venues. It was very sharp. The focal length was great for the full-size 11-a-side field. The lack of good depth of field was expected, but disappointing. In the end, that was a deal breaker for me. I returned the lens--no questions asked. What a great return policy! I'm going to try the Canon EF 300mm f/4L and see if that works better for me. Still, this is a great lens if f/4.5-5.6 works for you.

    I’m a beginner and found this lens to be very user friendly. My action shots were great and my close up shots were beautiful! I highly recommend this lens for action shots.

    Lens is ideal for traveling for its compact size and weight. Very sharp at f8-f11. I like the different image stabilization settings. Lock ring works good and stays tight.

    What I like about it is the long range zoom aside from being a sharp lens. Although it doesn't replaces my Canon 70-200mm f2.8 IS USM II. It is sharp from 100mm all the way to 400mm. But in a dim environmrnt, that is when this lens began to slow down. But the IS is a great help to minimize the blurry pictures. I find the IS very effective in all situations and it helps during low light shooting. I wish they should have made this thing with a "constant aperture." But it is an L lens, a very reliable one! Comparing to the Canon 200-400 f4, this is the way to go if you don't want the extra weight and also save a huge amount of money

    This Lense is excellent for shooting Sports & Wildlife. I have the previous one that zooms by push & pull. This lense twists left & right for focusing & it is very fast Focusing. You will not be dissappointed purchasing this one.
