TThis is a very nice & sharp Tamron 1.4x teleconverter for Nikon auto focus lenses that will keep all the autofocus functions of your lens. This teleconverter will give you a 1.4x magnification while retaining the image quality with only a 1 stop of light loss. It is ideal to add that extra reach to that telephoto or that zoom lens. It will fit all Nikon AF camera & lenses but the loss of 1 stop might make auto focus difficult with slower lenses for the entry level cameras. It worked perfectly with all of my DSLRs bodies from D300, D7100, D700, D600,D500,D800 & D810 with lenses like my 80-200mm & 200-500mm zoom lenses. I'm only selling because I now use a dedicated Nikon teleconverter.
