I have the 300mm pf and a Sigma 150-600mm along with a D780 and a D500. I do wildlife exclusively and mostly use the 300 pf with a 1.4x extender on the D780. Very flexible and mobile to catch birds in flight.
I have a Tamron 150-600 but having some back issues and can't carry it right now. Have the D500 and D850. I notice they are several 1.4's available, which do you have? Thanks!
