Granted, I like wide-angle shots. A lot. In the analog time my favorite lens was a 19er, but this is even better! I have since a few weeks in operation, and it has proved very successful, the 7-14 (or in small picture format 14-28) himself. The lens has a plastic socket that though fortunately very robust looks and operates without any play. Its MTF curves (to be found on the page Panasonic.net) do not look too bad, but only go to 40 lp / mm, that is, they are silent about the range resolution. After all, we are talking about the Micro Four Thirds system currently has more than 100 line pairs per millimeter! Nevertheless, the impression in practice is good. The results show no noticeable blurring, even with 7 mm and in the corners. Fringing do not interfere, and above all, for the figure's naked eye in the whole area is completely free of distortion. OK, for pocket money amounts there is this look is not for sale, even if they should be a little cheaper even in the next few months. But with respect to the performance of the amount is appropriate - at least I still look forward each time I use this lens in hand. Another addendum. In this type of system, the camera, the "white" so, what lens was placed, out-count the aberrations of the optical system again partially. The H-F007014E for example is actually not entirely free of distortion (at 7 mm approximately 5% barrel distortion), and it shows a clear vignetting. Both effects are no longer perceptible in the image captured (ie from the camera already processed). On one hand, it would certainly be better if the lens would represent the same "right", but on the other hand, the corrections made are so small that they do not lead to a visible deterioration of image quality in the post-treated areas. Let's assume that the same objective would turn a lot bigger and more expensive without the aforementioned mistakes - all in all a good compromise.
