[QUOTE="hark, post: 784395, member: 13196"] It looks like Sigma makes a TC for that lens. [URL]https://www.sigmaphoto.com/150-600mm-contemporary-tc-1401-teleconverter-kit[/URL] The problem is the TC will now make the lens a 210-840mm with a variable aperture of f/6.3-9 instead of its usual f/5-6.3. So when you are zoomed out to the long end with the TC, your largest aperture will be f/9. And that's going to cause an auto focus problem. Nikon has some bodies that will support f/8 as the largest aperture. Those bodies are pretty good with sensing light so they AF okay - albeit sometimes kind of slow. But your body isn't on the list. Will it work? I have no clue. This Nikon article should shed some light on this f/8 feature.
