Hi...

There are a couple of things you have to take into account with TC...

First is if you plan on getting and using Nikon TC's, they will only work on lens with AF-S, so any lens without AF-S will not work, as they do not have a screw drive connection between the camera and lens.
So to use a TC on NON AF-S lenses, you will need to get a Kenko, Sigma or Tamron versions that have the screw drive. All the metering and focusing will work with these TC's on both the AF-S and non AF-S lenses.

Secondly, the more multiplication you put on the worst your IQ will be. I have found using the Kenko 1.4x PRO300 DG TC, that I haven't any noticeable loss in IQ, and even up to 1.7x they seem to work well, but most of the shots I've seen with the 2x TC loose a lot in IQ or get soft.

Also using them on anything with more than f/2.8 will require that you have a lot of light, as you stop down the lens start you may then have trouble with either getting enough shutter speed for the length of the lens, or there won't be enough light for you AF to work correctly.

--------------------------------------------------
Nikon AF-S 18-70mm 1:35-4.5G ED
Nikkon 70-300mm 1:4-5.6 G
Vivitar 28-210mm 1:3.5-5.6
--------------------------------------------------

None of these lenses are ideal for using a TC, but that is not to say that you can't use them. I had tried my 1.4x TC on a friends 70-300G to see what it would be like and we were surprised at the IQ we got.

I originally got the Kenko 1.4x to fit to my Nikon 80-200 f/2.8, but shortly after getting it was trying it on my other lenses to see what results I got. Other than the 80-200, the best results I got from it was on my Nikon 50 f/1.8, and these were superb...

These are some samples (which have been heavily reduced for posting)....
