took me over confident. The price performance ratio. However, I must add that I simply it does not hold a professional and not a semi-professional amateur but a simple amateur photographer and likes to make street photography. I think little by about technology and solve rather out several times, along the lines of a successful picture is already to be there. What in my view, always was and still is. Each motif what appealed to me, I have photographed regardless of distance. From now on it will be much better with this lens. I am convinced after my first shots in the indoor and outdoor use. So far I have always given me only with zoom lenses. After typical men criteria made the choice of lens. Quasi greater the focal length, the better, the less has to be changed the lens and I can pull the trigger of a "safe" distance. By Festbrennweite my photography changed behavior. Apart from the positive effect on depth of field, sharpness and clarity of the recording in general and not least the incredible luminous intensity. I can not understand why I'm not much earlier changed to such an objective me. So from my perspective, I have done everything right. All amateur photographers who do not need to make money with photography can I make a purchase recommendation. And what one reads in the recession, it is good also for professionals. I agree with all the 5 star recessions and with full conviction.
