The lens has been packaged for 1 hour unpacking again and sent back to Amazon. My expectations of the optics were certainly not excessive. Who buys such a lens, should the design features and impact on the quality image to be clear - and it should also set value in a realistic relationship. Even while unpacking we had to "not the first" to have been the feeling of had this objective in hand. Wrinkled warranty card with dog-eared and torn, plastic wrap around the lens as. After repeated use and circumscribed little pollution at bayonet Well! Since the suspicion arises that this product has already begun way back to Amazon. Then the usual testing. Distortion and vignetting relatively high (expected, as must Lightroom ran - that can be corrected). Sharpness in the center mediocre. Upper margin fairly sharp - lower margin significantly blurred. Can this be? New Series with tripod and flash illumination - the lower picture area remains recognizable fuzzier than the upper. My old MF 3.5 / 18 mm showed better Abbildunsleistung. When I look at the test reports and MFT charts, then I can not believe that you want it to be "my" new lens. All freshly packed and back. I think I'll stick with Nikon and am at my local dealer, guaranteed original packaged, 4.0 / 16-35 buy Nikkor AFS.
