I can recession Mr Pertuch in all points but agree easily. Therefore, only a few additions from me: The haptics and workmanship are absolutely first class. The objective with the matt black coating is an optical Renner. It's not only wrong fun with it to photograph, it summarizes also tremendously well and is very smooth rolling. The sharpness of Abbilungen is inspiring. You have to take some time for this lens, however. In the macro range, the game with the depth of field and the exercise with different Blendeneistellungen is needed to get ultimately to the desired results. If you have the necessary experience, followed by immense fun. Fortunately, the E-520, the I use this lens, a built-in image stabilizer. Without this you would need almost necessarily a tripod or could only be displayed sharp image knipsen freehand.
