How to attach the Zeikos macro extension tube to Nikon D 5100 and to the kit lens 18-55mm? Neither side of the tube seems to fit the body of the camera nor the lens. Perhaps I bought the wrong item for my camera and lens? Any help to fit these onto the camera and lens would be appreciated. I have attached the pics of the lens, and both sides of the extension tubes. Kindly tell which side will attach to which side of the lens and camera. (note: I donot have the manual)
It appears that you have received the Canon EF-mount tube set, not the Nikon F (AF) version. The contacts and alignment aids are where you'd expect them for Canon EF, and the pass-through screw drive for Nikon AF is missing. Not surprising, then, that it won't fit your Nikon gear.
