I am working on comparison shots. I have an Af-105-VR, a +5 and +10 Subsee wet diopter and have ordered a 1.4 teleconverter. I will post pool shots this summer.

In my experience so far the Kento 2.0 teleconverter did autofocus somewhat but locked up and simply would not focus occasionally. In addition it was very difficult to hold the 105+2.0 steady.

Additionally, using the Subsee +10 directly on the 105 produced dramatic shots (attached) of 2:1 supermacro but autofocus is very difficult. My process is to have my buddy shine a small flashlight on the subject, move in closer than minimum focus distance, than back out till the subject is in focus. I have the camera in focus priority, C autofocus so the camera, no me decides when it is focus.

Using the +5 subsee is much easier.

I looked hard at the 200/4. The problem is the tripod mount collar is not removeable. I asked Nikon service if they could remove it and they said no. Focus is slow with this lens compared to the Af-105-Vr.

I also have the Sigma 150 macro. It did not provide a significent increase in the working distance so i did not see an advantage.

I have the newer VR 105 lens. I can't say it doesn't autofocus with the Nikon T/C only that the Nikon literature says it does not.

I am using the new 105. I looked at the Nikon tele-converter but it doesn't autofocus with the 105 so I opted for the Kento. My goal is greater than 1:1 so the 70-180 doesn't work for me.

Regards.

It does not appear that lighting is an issue @ 200+MM but focusing is difficult at minimum focus distance both with the 200MM F/4 and a 105MM and a Kento 2:1 T/C. Essentially, it is almost impossible for me to keep the camera steady.  I think I will back off to a 1.4 or 1.7 T/C.

Thanks for your comments

Bart-

Yes the 150mm lens has good magnification shooting skittish fish about 1-2 feet away. However, the slow autofocus seriously detracts from taking those shots.
