Vorneweg - it is a middle-class product. Medium high speed, highly visible under certain circumstances vignetting and some distortion in wide angle. But for the price is also not to be expected. But - that the tube does not unload by itself; at least one mechanical lock would have been nice. But that is the only drawback. The autofocus is quiet, fast and accurate. Even in Sport mode (when continually nachgeführtem focus) there are no problems. The enormous focal length range makes Normally the lens changes. However, the camera needs a halfway decent sunlight to make even good shots at 200mm. The vibration reduction works just fine; a real gain. The specified extension of the exposure time is realistic. The feel of the lens is very good, it makes a clean impression processed. Reflections in the lenses by lights (night scene) are excluded by the aspheric grinding almost. I had (unlike my previous lenses) so far no such reflection in the lens system. The lens hood is of course a bit short cut (not the point another way, after all, they must not protrude into the picture in wide angle) and as Innenfokussierer rests the front lens. Thus pole filter it and let's go! For me, the DX VR 18-200 is now become a commonplace used workhorse; other optics come only in special cases to use.
