    Yup, you can use them with your D300, or a D3, or any other SLR camera that you can change lenses on.

    Way to much for what they are, but I think they are about $140 for a set of 3rd party ones, and the OEM ones seem to be close to $100 each.

    *edit*

    I just went and checked, the Kenko tube set is up to $169!!!

    Nikon certainly does make them, but they are way more expensive then a 3rd party manufacturer, like Kenko.

    Hey Poseidon, is a teleconverter the same as what you were calling a diopter?

    Nope, a teleconverter goes between the camera and lens, a diopter goes on the front of the lens.

    For Canon, look for a 250D or 500D, I think Nikon calls them 5T, 6T, etc... Not sure on that one though.

    Which? Teleconverters from Canon cost about $279 and Diopters are about $100-125.

    You have to be careful, PHOTOGRAPHY can be just as addicting, an maybe even as expensive as REEFING!

    I have a Nikon D40 with the kit lense. I bought a set of Kenko extension tubes: 12mm, 20mm, & 36mm. If the coral is 4 inches back from the glass the only one that will focus is the 12mm. Is that due to the quality of the kit lense? I want to order the 105mm macro lense. Would that do the same thing?

    I'm kinda disappointed with them. In order to get a really good closeup I'd have to move the corals right up to the glass (which is not possible with some of them). I could probably get the same thing I'm getting now with crop and zoom in PP.

    H@rry, it is not the tubes that you are disappointed with. ;)

    And, for web purposes, you are probably right, you may get the same results with a crop in post processing, but for actual prints, you would notice a HUGE difference.

    That macro lens would be an excellent choice, and the tubes will become of much more use.

    Oh, just for reference, the coral I used in this example is about 9-10" away form the front glass.

    Kewl, 9 - 10 inches will work. I can reach most of my corals from that distance. Do you think I will get that much reach with the macro lense?
