As for the feel, there is no Kritik.Sämtliche mechanical parts run smoothly. After the first test images results in slight criticism regarding the topic "knackscharf". In the corners there are without and with dimming already compromising make. For this I was expecting a clearly positive result based on available tests. For lack of alternatives I'll keep the lens as my next available fixed focal length with 14mm wide-angle is not enough and has to also previously reported on limitations on the image sharpness in the peripheral areas.
