I write as a photographer, not a lens tester, the lens still active in temperate macro area amazing. At the Nikon D7100 also small picture cutouts provide remarkable sharpness. Of course there are better optics. But these are either fainter, have a smaller range of focal lengths, or have ever fixed focal lengths. And anyway, there are photographers who think it's great to bring plastic lenses on a D800; They could be either the same, find fault with the slight edge blurring of good lenses? Almost every photographer adds sometimes added in Photoshop vignetting; but what a disaster that even the most expensive lenses have a slight tendency. Photographers for the photo is one that I would highly recommend this lens highly. It's the best Universal Zoom, I've ever had. For special purposes, I have a few very good fixed focal lengths, but which I did not often take with.
