A great lens!

How does the 2x TC affect CAF for depth changes?

Actually, I don't have a clue, since the 2x converter is of no interest for me. Here others have to chime in!

The A7rIII need f:8 to focus fast and precise. If I had the GM 70-200 mm f:2.8 or the awaited GM 400 mm f:2.8, I would go for the 2x converter. This 400 mm lens will be too expensive for me, though.

Thanks, great info.  I didn't realize the f8 limitation.  Is that for the A9 too?
