The lens is now already almost a legendary reputation of being the it - to anticipate it - deserve full. The light intensity is not objectionable, the image sharpness greatly. The distortion falls given the enormous wide angle moderate. The build quality is top, the same applies to the accessories (albeit a lens hood of course is very limited in a super wide angle effectively is). The lens cap is a bit strange, because it is simply pushed only without locking possibility; Due to its size it will go but hardly lost. The missing filter thread is the tribute to the curvature of the lens and personally to get over well for me. For architectural, landscape and travel photography certainly a must if the price is still within the budget!
