positive:Sturdy, well built lens. Sharp at f/2.8 at longest range. Reasonably priced.
negative:A bit soft wide open at 28mm, some flare.
comment:Originally bought for my 700si, but has followed into the digital era. It's a good low-budget lens, which delivers nice colours and overall good sharpness. Especially on the long range, which makes it a nice portrait lens on the 7D.
