Property me the O. bought due to some reviews, and may those who say: "not need to" agree. If you try to focus on an object that is located in the "range of infinity", one has simply had bad luck, it is not. If you also adjusts to the longest focal length, you're afraid that thing breaks right through. That it does not, but the game to which you can then raise the camera does, do not bode well. The part can then bring no good shots more, unless there are built-magic rubber lenses that adapt to the curvature of the lens automatically. No issue on which price you can not expect much, but too bad it can not be easy. Anyone who thinks seriously in order to be able to shoot good pictures, it should try for yourself, for me, the part is an absolute NOGO. Too bad, because where there's already 1.3 mtr focal length for 270 euros? Nowhere precisely.
