Will you have any tests of this lens with the FE 2.0 teleconverter? Wondering how sharp it will be at the 200mm end on the A7RII or A9 compared to the Sony FE 100-400mm f/4.5-5.6 GM OSS Lens at 400mm. I like the idea of having the option of having a 2.8 200mm option for low light situations but not sure how much sharpness and auto focus speed will be lost.
I was told by a local sony rep that the new stacked CMOS sensor technology in the A9 may improve the next high resolution camera body's autofocus system technology (possibly A7RIII) which may make the use of the 2.0 teleconverter faster as well.  What are your thoughts on this? Thank you!
