I suppose it depends on whether the bigger pixels on the Z6 will give less noise and 'better' images than the Z7 in DX crop. For many, 24mp is considered enough for their needs. Why pay more for pixels they won't use and potentially get lesser results when they crop? What's interesting is with the D850 and presumably the Z7 we are seeing increasing numbers of cameras with sensor densities that exceed the (presumably now outdated) conventional wisdom on how many pixels we should pack in and still get quality images out at high ISO's.

Yes I agree with you but the D850 sensor grain/noise is probably less than the D3. Agree with you about not having too many pixels. It is a balance that can vary with every person. Initially I thought that the D800 was too many pixels but I see a major advance with the D850 and the D800 is now my second string camera. The D600 is for sale! I think the noise is down to the supporting chipset EXPEED which in the Z7 is EXPEED6.

Did a bit of rough testing today. My Nikon 85mm f1.4 AF-D on FTZ adapter versus the Nikon 24-70 f4 Z series lens. I hate to say it but my 85 was not nearly as good as my 24-70. Need to look at more of my lens a**enal in the light of this initial testing.

Methinks the 85 needs the right subject... My understanding is it isn't so much what should be sharp but the rendering of what isn't sharp with that lens. Try the 105 f/2.5, that will test it.

Yes I have the 105 AFS VR which should be good. I will test that as soon as I get a chance.

It was the AI MF version I was referring to. AF's no good on a lens like that!

AF is useful for initial focusing but useless thereafter in macro photography. The Nikon 105mm f2.8 G AF-S VR is meant to be super sharp and I have no reason to doubt this.

Well got to say that DPReview are not my favoured test reviewers. However they do seem to be relatively positive about the Z7. https://www.dpreview.com/reviews/nikon-z7 I really have found few problems moving to use the Z7 from the D850, D800 or D500. One or two differences Yes but no show stoppers. There is some mention of shadow detail striping which might make it less suitable for astrophotography. I find the AF in low light is less certain or more hesitant than the D850/800/500. Small things but only because I am used to an alternative better in these conditions camwra! The advantages of mirrorless faf far outweigh these limitations.

As far as I can ascertain the banding only appears when in a normal photograph (as opposed to a night sky image) the dynamic range is pushed in post processing by excessive use of shadow recovery. Even then the noise reduction software in the NIK filter set is said to deal well with the phenomenon. This should not affect night sky images which are correctly (sufficiently) exposed because usually dark detail isn't required. Boosting dim stars, nebula, gas clouds etc. is usually achieved by layering techniques which shouldn't require push processing of shadows.
