Z6 banding is this normal?

1. I'm guessing this is normal?

2. Any way to avoid this?

3. Is this part of the recall issue that Z series had? I've checked the serial number no issues.

The Z shots don't have it 100% either. Only the Canon seems to have it across the image in this particular test. Point is, it's there on all of them. Sony just seems to be ahead of the pack on (nearly) eliminating it, to no surprise as they have a few years of development over everyone else.
It's not that Sony eliminates it. They merely don't create it. The effect isn't there unless you do (misguided, IMHO) in-camera processing to mitigate PDAF striping.

Jim
They have striping, no? Point I was trying to make is they all have "something" that results in the same thing - lines of noise across the image.
But the striping occurs far less often than the banding,and never without the presence of lens flare.

That's just a single image, and the A7III doesn't show any striping/banding there either, but we know it has it. I think Jim has shown that one image alone isn't reliable, as the effect is difficult to reproduce.
Horshack did the heavy lifting on this. I just spotted for him.
All this shows is that the one image captured in this lab test did not produce any banding on the sonys.
I have never seen any PDAF banding on Sony cameras, in 100,000s of captures.
"Striping" or whatever the correct term is on the sonys.
And only occurs in the frame location of a lens flare reflection, is exceedingly rare, and only manifests with very specific lenses, such as the Sony 85 f/1.8. We can't ignore the relative frequency or severity of an issue when comparing cameras. Unless the purpose of that exercise is to paper over those differences.

Fair enough. Here's to wishing Nikon figures it out sooner rather than later.

Do you think this is something that can be addressed via FW or hardware only?

Here's the bright side. Nikon created this problem when they wrote the firmware. Nikon can fix it by rewriting the firmware.

And BTW, I don't use the a7RIII any more, though I still have two. I do use the a9 from time to time; it still is unique in its feature set.

That's great news then.

When it's fixed, we'll see striping. But that's a lesser problem. And it, like PDAF banding, is fixable in post.

The banding investigation threads supplied definitive evidence the Z's banding is the result of intentional post-capture processing by Nikon, which means it should be fixable in a future firmware release, assuming the processing causing the banding is being done in firmware or, if done on Expeed instead, can be disabled via a hardware configuration register. But I'm guessing this won't be addressed - the Nikon engineers who implemented it obviously think the "solution" (PDAF banding) is better than the problem they're attempting to avoid (PDAF striping).

I'm all for the lesser of two evils.

Well, if this keeps getting attention, they can't ignore it and they will re-visit the engineer's "solution".

Nikon is uniquely adept at ignoring issues even far more serious than this, such as the sensor oil issue on the D600. They usually only respond to sales trends and class-action lawsuits.

That is an extreme push ,
I disagree. This is an appropriate tone mapping of the shadows to resemble the scene for human perception
perhaps try exposure bracketing if you want information in the darkest and brightest area of a subject with such a wide range
Recent Nikon DSLRs can achieve the same, without the banding. That discrepancy should be resolved first before putting any onus on the photographer to exposure bracket.
There is nothing reasonable about that level of pushing, if you need to push 5 or more stops I am afraid you are doing it wrong. When a quick burst of bracketed shots would give you far more information to play with. Sometimes the photographer has to put a little thought into it. I believe that there is also a way to fix the banding in post using certain software.
What is undeniable is that the Zx's have less dynamic range in these circumstances than they would if they didn't have the firmware corrections. If you don't need the DR, then the banding doesn't matter. But many have extolled the Dx cameras DR, only to find out that there are times where they can't use it.

Jim
Jim , I am absoloutly not denying that the issue is real, just proposing methods that can circumvent it at capture or as Horshack has demonstrated in post with appropriate software. i would suggest that using these methodologies will limit the scenarios to where you cannot achieve very wide DR.

To me the D850 is smooth and all of the PDAF cameras are not in the DPR example Horshack posted, use whatever term. I can see it in on screen without even blowing up the examples.

These are the other examples I have seen:

This all goes back to, who pushes picture ten freaking stops. This really is a waste of our time.

And there are ways to get more light into the shadows, just as you proposed. But many of them, like combining bracket shots in post, don't work for many dynamic subjects. But if your point is that there are workarounds, I agree with you. If your point is that you never need a 5 stop local push if you're doing it right, I don't.

Another way to deal with intra-scene DR is graduated filters, and that approach works with moving subjects.

I was responding to the image presented by the OP . A subject which could have easily been taken with bracketing . If there is a simple straightforward well known and easily facilitated { in camera in this case } feature to take advantage of , I would indeed suggest that the photographer is in this instance doing it wrong. If there is no possible method , technique , post processing or any other way to ameliorate the phenomenon , then the photographer is entirely unimpeachable in his actions :-)

As I mentioned there will be scenarios where it is more challenging . Though you are still left with other options such as the fix in post or as you suggest below the use of graduated filters again an extremely common and well known method especially in the landscape photography field, where wide DR subjects is very common
Another way to deal with intra-scene DR is graduated filters, and that approach works with moving subjects.

This topic has a tendency to generate more heat than light. Is it a problem sometimes? Sure. Is it a BFD? No way.

Here's my perspective on the issue:

Jim
Dpreview should add a forum auto-responder that replies to any thread with the term "banding" in the subject with a link to your article, then automatically closes the thread :)
There are many over in the m43 forum who would love such a feature for the word "equivalence " If you are looking for some votes :-)
