>I have read in a book (G. Richter: "Nikon F5") that "the >TC-16A has too many limitations to be useful at all". >What kind of limitations/drawbacks are these? Please help! There are a number of lenses which will not mount to the TC-16A. I tried my 70-300 f/4-5.6 AF ED; it would not mount. If you are planning to get the TC-16A, make sure it will work with all lenses that you intend to use it with. Bill Cassing
