This lens is in my opinion wrongly made worse than it is. I compared it with my Nikon 35mm f1.8 35mm with that gets a lot of praise, but can not detect any significant differences with the best intentions, only that the 35mm / f1.8 is just brighter. Ok, the sculpture seems not very valent, but the weight is very low and therefore it is my plan always on the go, if I do not want to lug much.
