<Compat...(恕刪)
看了一下官方所附的表之後發現 被標示不能對焦的鏡頭光圈都在4 裝上2X後即為8
Nikon的對焦 最小好像只到5.6？ 所以對焦才會變慢吧？
猜想是這個原因造成對焦過慢（進光量太少…）所以官方才保守說不能對焦…？

Yes you're right, even the 105mm VR macro will be categorized as non-compatible because the design of macro lens - maximum aperature will change when focus distance is shorter than infinite (according to the design of Nikon camera), F2.8 may become F5.6 when shortest focus distance, times 2 = F11 and then will be categorized as non-compatible.
AF-S Teleconverter TC-20E III
you can see AF-S VR Micro-Nikkor 105mm f/2.8G IF-ED has a *, which indicated: Autofocus cannot be used.
However, regardless the compatible table, I've used 105mm VR with TC-20E III, AF still works fine.
^^A 請多多指教~
