I use this lens for about 6 months quite often - it's because compact, the standard lens on my camera (NEX 5N). For leisure, landscape and architectural photography I appreciate the quality of the images produced. The from and to criticism of the optical characteristics of this lens (distortion) is probably correct, but not relevant to me as an opportunity photographer -. The curvatures, eg of horizon lines fall so from low that I not do it without the hint from reviews would benmerkt. In combination with the NEX results with this lens a compact, powerful "Camera" for everyday life.
