I've been using my TC-14b with a 300mm Ai-S ED IF Nikkor f/4.5, and it works really well. It adds only a little length and weight to the lens, and the pictures are still nice and sharp. The unit is very small and sturdy - like a metal hockey puck.

I use this Nikon TC-14b 1.4x converter on my Nikon 400mm F3.5 EDIF and Nikon D800. It gives me a 560mm F5 full frame. On that camera with that lens it does not seem to loose much quality with the converter. Maybe if anything a little softer in corners but I am being picky. Also I now have to stop down one stop to get the most out of the combo when before I could shoot the lens wide open in most cases and do well. These are not unexpected results though and I am more then happy with the combo. Especially for the price!
I don't notice any degradation of the image when using this teleconverter with a Nikon AI-S 600mm F5.6 lens. If you want to try the old MF Nikon Professional lenses this is a great value. You may even find you can get a few BIF shots.

Did a bit of investigation between Nikon teleconverters and which lenses they were designed to work best with. I own a Tokina SD-ATX 300mm f/2.8 and getting so-so results with my TC-201. Decided the TC14B would be the best way to go and not lose as much sharpness. And I was completely correct in that assumption. Ran tests both on film and digital, heavily damped tripod w/mirror lock up. Aperture settings from wide open to 4 stops down. Immense improvement over using the TC201. Next I'm going to try out a TC301 and see what I can get with that combo.
works as expected. images are sharp
