I use this lens for event shooting about 80% inside and 20% outside. This lens has never failed me the focus is great and spot on every time. The reason for 4.5 stars and not 5 is its not as sharp at the long end as the wide end. I have used it on both a 7D and 70D. I like the colors and it has very little CA or distortion. daveView review in forums Leave a comment on this review
