Wildlife photography, crop sensor or full frame?
I’m a wildlife photographer. I’ve been using an entry level Nikon d3400 with a Tamron 18 to 400. It’s time to upgrade my camera. I like the extra power I get with the crop factor, but it seems like getting another crop sensor camera like the Nikon d7500 wouldn’t be much of an upgrade. I’ve been considering a Nikon Z6. I loose the crop factor but gain what I think is a much better camera. I’ve narrowed my choice down to the Z6 or the d7500. Constructive thoughts would be much appreciated.
