Hi Orrie,
FYI, the Nikon site only recommends the TC-14E III with the AF-S-200-500MM lens.
But I have heard of shooters stacking two of them to get double the range.
Not a cheap option, but neither is the 80-400MM with a teleconverter.
you need to recheck the chart, the TC-14E III is the only one that you are able to use with auto focus with cameras that have an internal focus motor, the TC-17 and TC-20 may be used with manual focus, but be aware that as with any lens, when you use a teleconverter, you will lose light and sharpness, the larger the teleconverter, the softer the photo.
