I have been testing the D850 with the big 500mm AF-S f4 lens for first time with the x1.4 extender giving a 700mm lens. Depth of field is a serious problem and even at f9 focus must be spot on. This was dull light today so 1250 ISO and 1/800 sec at f9 hand held. Even with the x1.4 extender the Sparrow is not even 1/2 of the total frame size.
