Great lens to pick up if you can find it cheap used. Easily a match for its big brother in the "L" gang, but not wide open. Very nice soft focus feature, razor sharp when off, dreamy effects when dialed in.
Small; light; razor sharp; although not edge to edge like the big brother "L"
Lens flare is very pronounced even with a hood against even slightly backlit subjects; Build is cheap; Not a lens I would take through a rough outing
