Reading some of the comments there are some interesting and informative comments...........
I feel the range of lenses Nikon has in its stable is amazing, as usual over priced in my mind, but a huge selection, you could build a great system around the
Z6III especially with a 28-400 and a 50mm 1.8s, or 24-120, 100- 400 and a 50mm 1.8 S.
For myself the Z6 III is an exciting and welcomed up grade model from the original Z6, it also highlights some of the new features no doubt will be forth coming in other camera model upgrades.
24mp is perfect for so many people and applications especially when you look into what the camera or tool actually achieves.
Cropping or more so switching to DX mode on a 45 or 60 mp camera is one thing, doing that on a 24 mp FF is another.
For myself there is absolutely nothing wrong with the Z6III, its a brilliant tool that has a purpose, i would be happy to have one but it just doesn't suite my tool box for what i do or need at this point in time.
If your not doing wild life sports action all the time then a combo of
A Z7 III and a Z6III especially with a 28-400 and a 50mm 1.8s, or 24-120, 100- 400 and a 50mm 1.8 S. is nice tool kit to start with, also when you work out the cost you nearly get 2 for 1 cameras.
Only an opinion
