Adam;

You are basicly shooting a 21mm rectilinear f/3.5 lens. Yes, less distortion, but remember you can fix that very easily in LR.
I'm just back from shooting the 16-35 in low light and am not impressed, it quickly jumps up to f4 and won't catch focus.

I'd have to believe that shooting the scene with the fisheye lens alone and then cropping the image to the same framing as the fisheye plus the kenko tele-converter would produce sharper results. A fisheye lens is the exact opposite of the type of lens tele-converters were designed to produce the best results with. The D800 allows you to choose several different cropped formats to shoot in and you could do that instead of shooting and cropping the full FX image.

I'm with Alex on that - No need for a Tc with the Sigma 15 fisheye. You can get closer, croop or take the pic on X1.2 or Dx mode.
The 105 works like magic with the Kenko 1.4 Tc. My 60 2.8 afs was hesitating with it.

That's also my experience. The old 60 mm is working with it though
