Thanks for all the great input, everyone! I want to do some more research, but I'm starting to lean towards a 7-element Kenko. I think when I get my D back from the shop, I might buy the 1.4x and the 2x and test them both with the zoom I plan to use them with. I'm going to ask around but my lens might be too new for anyone to have tested it much. Thanks, Amita
