[quote:d9cc1909cf="tbob"]Wing,
The Nikon UR-E14 tube is 38mm. I can't remember what camera you have but with Nikon 8400, I take all (nearly all) my shots at one zoom position. This position is just at the end of the macro (green flower) position. I have found that in this position the autofocus works extremely well.
Because the Nikon 8400 has a wide angle zoom it is not possible to zoom the full range without getting vignetting, on my Casio I can zoom the full range

Bob,
Thanks. I just bought a new Nikon 8400. I think I need to buy the original Nikon UR-E14 tube. The tube made by the third party is 40mm.
Where can i get the UR-E14 in Hong Kong Kong, any idea?
