For this price, there is no comparable good and sharp lens. Can not miss any collection. Small, handy, lightweight and especially knackscharf. Even at full aperture, the images are more than useful, a bit soft, but here are worlds between a push and a fixed focal length. Abbgeblendet on panel 4 to 5.6, it is absolutely awesome. Such perfect contrast and sharpness performances I have seen in any other lens. If more budget available, I will immediately order the even more intense and the big brother 85 1.4 1.8 :)
