A7III posterization banding

[Ishigaki]

Recently I've noticed that many shots taken with my A7III (particularly using the 16-35 F4) contain very severe posterization banding in the sky. I'm shooting with silent shutter disabled, and to uncompressed raw files - the effect is clearly visible in both the raw files and the JPEGs. I initially noticed it in a shot that was underexposed by about a stop, but it's also visible in my daytime shots that are correctly exposed (although less obvious).

Has anybody else seen this? Any help would be much appreciated.

I've attached a JPEG that illustrates the issue in the sky - the uncompressed raw files exhibit the same concentric circular banding.

Your eyes are far better than my 75 year old peepers....after close examination all I can see are what I would guess are telephone wires and clouds!

Definitely there and definitely grim.

No, I haven't noticed this in my pictures.

EXIF says Software: Adobe Photoshop Lightroom Classic 8.0 (Windows). Try a couple of other converters to confirm. You can download Capture One for Sony and RawDigger to try them out.
