TC for 80.200 2.8D

The kenkoPro 1.4 (they don't make a 1.7) is a great tool. Playing around I've stacked it with my Nikon Tc.17 (see the post below "300 AFS @ 750". When I used it with my 80-200 I don't even notice any reduction in quality.

Do a search on KenkPro and you find that it is the standard for non-AFS nikkors now.

 

If you use the Kenko 1.4x PRO300 (Tamron is apparently a Kenko) you should not really loose any noticeable IQ, but if you get the 2x, there is a high chance of soft IQ on the 80-200.

Also you cannot use the latest Nikon TC as they will only work on AF-S lenses. But be aware that with the Kenko, it will not show up in the EXIF data that you have a TC attached...

There are a few samples from a 80-200 (2-ring) with a Kenko 1.4x PRO300 TC....

Also if you go to Nikonian site and then the Nikkor Lenses posts, there is a post on "Teleconverter Compatibility Chart"

In theory, yes. But at the long end of the 18-200, you'd be operating at f/8 wide open and that is a bit slow for auto-focus (Nikon does not guarantee proper AF operation above f/5.6).

The Kenko 1.4 Pro is compatible with pretty much any lens, unlike the Nikon TC (even when modified for operation on non-AFS lenses), because its design does not intrude into the space that a back glass element could use...

 

You can find a very reasonably priced Kenko PRO 1.4 (New) from a Hong Kong supplier on the great auction site.
