Having purchased a UV filter lens for a newly-acquired second-hand Nikon zoom from Calumet, I ordered a lens hood for the same lens. The wrong one arrived: these things happen. I then explained that I needed the correct one quickly, to meet a travel deadline. I was assured that Calumet would phone Nikon to see if one was in stock, and would phone me to let me know if the deadline could be met. On my phoning Calumet (not having heard anything) I was told that Nikon had the item in stock, that the deadline could be met, and that I would be notified. On my making contact again (having again heard nothing) I was told it was very unlikely that the (now very close) deadline could be met, because "Nikon were often slow with such matters". An E-Bay supplier came up with the goods overnight and at a quarter of the price. I'm aware that a lens hood is small beer compared with the expensive equipment available from Calumet: that does not excuse the poor customer service.
