"Sony has a SERIOUS striping issue (some models affected way worse than others), no idea why you claim it has none."

Then I wonder why there's no visible banding in the comparison? I don't blame you for using Canon, but I blame you for ignoring that the ability fo pulling shadows up if necessary. It seems like a plea "I don't need that, because it's fad." It's not, if done properly, but keep on ignoring it.

Which comparison are you referring to, JoJu?

I will say it again. The Sony PD AF striping issue is NOT a noise from lifting shadows many stops issue. Your confusion about that is probably to blame on martind86's post which linked to a Nikon D750 vs 5D mk IV many stops shadow pulling contest, which has zero to do with what can occur with the Nikon Z sensor.

The stripes issue (a Sony live view ("mirrorless") PD AF thing) has to do with light at certain angles shows the masking of PD AF pixel lines. Sometimes becoming (more) visible when brightening the file, sometimes clearly visible when using the standard tonal curve.

Whether it may affect images you take depends on many things: the (wide) angle of the lens, or the big aperture (Sony 85mm f1.8 often reported?), the way/amount of back light(s).

And now the Nikon Z7 shows this Sony ill too, according to front page reporting by DPReview.

I finally found this elusive Z7 banding issue after putting on my glasses.....very fine, but there......it's not like a lot of wide banding and isn't difficult to remove, more like "hatching" really.

     Nothing at all like the D7100's banding......which was coarse and easily visible.....forum users said "you had to look hard to find it".....but in any sort of sunset shoot produced it in the dark horizons, for me that made it a flawed camera.......I was glad to find the D500/D750 doesn't do it.......it was simply horrible!

     The Z7 is more of a "search long enough and you will find" I'm not sure to what size you have to print to see it at all?.......

   The sensor is a quiet back side variety with PDCDAF, so there is the possibility of issues in certain lighting......but at this stage of the game I would expect and hope Nikon will fine tuning all these little pesky micro bugs with a steady flow of FW updates, this is Nikon's first sortie into ML.....overall they have done a remarkable job.
   Canon have been doing PDCDAF sensors for years......so I'm not sure what their excuse is?

     Still it gave BC the opportunity to waive at least a tiny flag.........something that Canon users haven't often had a chance to do over the last few years.....

There is no FW to update on this issue, Dave. It does not affect all images, and is not a firmware issue.

Excuse for what?
