Been shopping again before the rand rolls gear up even more.
Not sure if this is the a good way to compare or not but here goes.
D800/Nikon 70-200 F4 with & without TC-20E -III.
Just cropped & resized for web,no other alterations.
Shot in Program mode to try keep the exposure similiar.
Used DX image area for both.
Its a cloudy,overcast day here.
I did some comparisons myself today. I was wondering what would get me to around 800mm for cricket - a fullframe with a 2x on my 400mm f/2.8 (total 800mm) or an APS-C with a 1.4x on the same 400mm (896mm). I was actually a little surprised that the full frame combo gave me significantly better results.
This is probably a comparison I should have done at the beginning of the season…
