Thanks Randy for your quick reply. I suspected the 16-80 + FTZ would seem unbalanced on the Z50 (although a YouTuber reviewed the Z50 + the Sigma 17-70 (similar in size and weight to the 16-80) and he really like them together. Just not sure the benefits (size, weight, better AF, supposedly the VF, etc) of the Z50 kit + FTZ + a gently-used 16-80 are superior to the D7500 +16-80 when factoring in the cost (the Z50 scenario costs about $500.1st off the 16-80 is 10 steps up
I tried the 300pf but not the 16-80. Using the FTZ and a heavy lens on the Z50 seemed counter productive. But in the end the VF was a show stopper for me.
I guess it comes down to my own preferences; I’ll need to try both options out.
