Weird A7R II Banding

[3kramd5]

From the first ISO 6400 raw out there:

Looks maybe like the effect of an adjacent hot component?

Seems fairly simple to NR is out (processed by a sonyalpharumors user in Capture One), but it gets waxy. Disclaimer: this is likely from a pre-production camera.

Full res jpeg here.

Not exactly perfect is it?

 

[Viggo]

But LOOK at the DR! Oh, wait...

 

[Larsskv]

No worries! They will fix the banding with the A7RIII, which will be announced later this year.

haha!

Evidently it was Capture One creating the effect. DCRAW (see below), RawTherapee, etc. don't do it. Lotta chroma noise in the DCRAW image.

There is reason why, we shouldn't look at early pre-production bodies.

Well, if this is software-dependent (as it looks), files from the production body could exhibit the same problem on the released (not beta) Capture One 8.3.1.

Or use software that is not yet ready for the new body.

Certainly not the first time that's been an issue leading to inappropriate conclusions.

At what point do you deem it "ready"? The release notes state:

Highlights, Capture One 8.3.1
This is a service release providing bug fixes, lens and camera support

Camera support
• File and tethering support:
Sony ILCE-­‐7RM2 (a7RII)

I'd deem it 'ready' when it doesn't introduce artifacts into images.

Interesting demonstration of software effect.

... which you won't know until you use the software

This is probably because no color NR has been applied. DCRAW is just a low level RAW processor. CaptureOne is a high level processor, and like Lightroom, it applies a certain amount of color NR by default. EVERY RAW image actually has this color noise...you usually don't see it because high level raw editors are cleaning it up for you.

... which you won't know until you use the software

...which should have been tested – and corrected – before the software was released purporting to support a given camera.

Yes, Matt Grum said as much. There is zero NR applied to the DCRAW render.

Indeed. Should. Pitty these companies race to get things out there. It's like they want bragging rights for saying "first." Similar infection as many news companies.

Few issues I have with a7 series are battery life and AF tracking. IQ and high ISO(including a7r) never been an issue.

I was worried the had copied the canon shadow banding feature /jk

at first it looked like moire, I'm glad you found the cause before we popped the champaign to celebrate at sony's misfortune.

The disclaimer should read as follows: "this is from pre-production software."

8.3.1 is an official/final release.
