Not that brave I had been photographig them for a week with a game ranger keeping an eye on me. They are not as dangerous as Black Rhinos and they were more than happy with us being down wind.
Far more interesting is my progress with the D850 in very dull rain this morning very poor light, 80-400 at 400mm plus x1.4 this is about 1/2 the full frame. 1/650 sec f8 ISO 2600. (Is this all you need!!?)
Many bird photographers still believe that the bird only needs to be 1/3 of the frame to ensure a good part of the habitat is part of the photograph. The fact you are able to attain such clarity from that crop suggests that, YES, it may well be enough.
So FX400 x 1.4 = 560mm, cropped 1/2 full size ....so 1020mm equiv.
DX270 x 1.4 = 567mm
So the question is....... if you had put the 80-400 with the 1.4x tc on the D500, set it to 270mm and done the same 1/2 crop, would the image have been as good?
Grasshopper feel the force. The paper in your wallet will not feed you!
Get the 200-500 and be done with it.
It's a possibility Jonathan, if I find the 300+1.4tc falls short of my needs.
