A9_03579

1120mm @ f16 (1.4x+2x on 100400GM with Kenko 16mm entension tube).

 

Only 1st attached teleconverter will be register in EXIF, a9 will still do AFC @ 20fps with v5.0 firmware @ f16.

 

Real-time tracking mode wont work with this setup, Wide/Zone tracking still works.

 

1680mm f16 (2x+1.4x) with 200600G / 2400mm f16 (2x+2x) with 640GM setup.
