Since the announcement of this lens I was intrigued to try it on my Nikon D7100. It should my Nikkor 16-85mm f3.5-5.6 replace, even if the focal length range is different. Unwrapped, it is a very nice Trumm. Well, somewhere the light intensity must come from somewhere. The processing is at first glance very well, without any flaws. The design shows that it is not here a 0815 lens. The lens hood is seated firmly on the lens, sometimes you have already vigorously applying torque to remove them. For my taste in daily use too much force is necessary. With regard to the weight - a battery grip to the camera does not hurt, but can do without. Worst is the lens cover, especially with an attached lens hood I succeed after several attempts, this set up properly. Surely even the least important part, but the scratches on the entire appearance. Just as the AF / MF switch, also goes very difficult. The focus ring and focus ring run absolutely smooth and smooth - felt better than some professional Nikon lenses. The feel is surfaces is otherwise very good, everything feels very valuable. Now for the optical properties: sharpness of motives is from f 2.8 upwards in the center and at the edge crisp, more you can probably not rausholen from the sensor. As fixed focal length in the focal length range or better. The images are high-contrast, color, and sharp. Very impressive. The only downer seems to be the AF, which does not sit still. For interior shots and playing children absolutely unsuitable. Brilliant contrast for Archtektur-, landscapes and cityscapes, since it is my Always top! become and has replaced my 16-85mm. Due to the size and weight it competes only with fixed focal lengths ...
summarized; Particulary good: - Unrivaled sharpness of images and even at aperture 2.8 over the entire focal length, since catching other lenses at first; good image contrast, fine color reproduction - Use of manual focus and Focus very supple - Feel, value and design
less well - Lens cap can be sometimes difficult to de- / mount, AF / MF switch is also quite heavy - Autofocus does not sit still, but sometimes in other lenses too, which is still under
really bad - Lens cap must sometimes be purely hanky
The price is quite reasonable for the performance. I also have the Sigma Dock, have not yet used but, since I could not find the back-front focus issues.
