Now, the D300 has fallen with the Nikkor from about one meter in a dusty, sandy soil with stones less than 5 years. The lens aperture (HB-40) is broken there! The lens has remained intact. I had it though disassemble and thoroughly remove dust, because there was dust come in the zoom ring, which is why he was stiff gewordne, but now it's like new again. Insbesonder amazed me that the auto focus has not shifted. The extra charge to Konkurrenzprodkuten is also the objective value, because it is built cleverly. First of it is made of metal and not plastic (hence the weight of just 900 grams) and therefore keeps out a lot, as I have noted. Then the panel is also designed so that it forms an approximately 1 cm margin around the lens housing, so that, in the event of a fall, the iris and not the Gehäsue or glass abbekommt the force. Hobbyists find instructions on Youtube and technical plans of Nikon how to disassemble itself and can dasObjektiv oils. In the first version of the lens, ie, the I own, the zoom ring has been sluggish due to normal use by itself after some time. Apparently this problem was corrected in the revision.
I've never regretted the purchase and who will umliest in the forums soon notice that one acquires a reference lens. I use it with the D300, despite being a full frame lens. Clear I do not use so the full spectrum and have a crop factor inside, but as a photographer you develop (hopefully) and soon I will move to a full-frame camera.
