Cons: Its a big lens! May be too big, but nice constructed. Cornershading on fullframe.
Pros: Optically one of the best lenses in the Sigmaprogramm. Very few distortion, very few cornershading APS-C, beautifull colores, sharp from f4, not much CA´s.
Summary: A nearly onknown lens, thats a pitty. One of the very best Sigmalenses, good construction but a bit big. Sharp and great colours, resistent to flare and CA´s.
