Just seing the image, before reading : it is exactly that.
You get what sensor moire is.
And PL8 does not offer any convinient solution to attenuate this enough in cases problem is very obvious.
Dpxd did gave better results most of the time with or without moire correction.
DPxd2s + moire correction is really better than dpxd with the luma component (nearly visually as perfect as possible on samples I checked) but the hue stays so visible that it ruins the benefit of the luma correction (but it seems it correct this the best possible way for black and white output - since I don’t think a magic algorythm can retreive original real pattern of those details).
Moreover, change in sharpness fall off (softness correction more rapidly less pronounced when sharpness decreases), decreases enhancement PL provides for wide aperture shots with relatively thin depht of field on subject (which is a very common way of shoting birds for many reasons).
And sometime blurred background looks a little more blotchy in those cases.
(I won’t talk much of the link put somewhere - yesterday I think - on the forum of a youtuber saying it is good and showing a bird big like a confetti in the frame).
So I think a (very) little step back for many birders who seach to get as much details as possible (mostly this sharpness fall off thing).
This is what I see on my images with my equipment. Other may have different results ?
I would have like that bokey parameter in lens softness compensation deal with those behaviors and allow to choose fall off extend for added sharpness when sharpness decreases in original shot, but it does not (or maybe with a so tiny expand that it does not allow to get previous results and it’s result is not visible in most of my shots).
Just went through my Z8 sports photos and couldn’t find any with obvious moire. Maybe because they were mostly shot with 135/1.8 and 70-200/2.8 lenses wide open and the T-shirts were usually slightly OOF, where lens acts as a low pass filter substitute. Maybe the movement was often too fast for a pixel-sharp 45mp photo, even at 1/2000 sec. I suspect that experienced fashion photographers can tell at a glance, if the fabric could cause moire and at what distance (to get “resonance”) – they have to use longer DOF, so moire can be bread and butter for them. If I remember correctly, PhaseOne or Hasselblad have a weak AA-filter, if any. Anyway, the topic became less interesting to me, as I’m rarely affected even with Z8, it seems, and never seen moire with D4 or D700 (but the D780 is prone to moire). I shoot birds only incidentaly, and then I take many photos, so no big danger there.
Some links: https://www.lightstalking.com/moire/ – moire from the photographer’s point of view. Nice introduction but perhaps there are articles with even more moire types. EDIT: funny statement there, that increasing exposure time may reduce moire – but that’s just because of camera shake.
Bayer moire | LibRaw – moire, as seen by a programmer. Slightly outdated, but still a good read. Citation: If, all of a sudden, your camera/lens can create a pixel-sized contrast object on the matrix, you can never predict what color it will be - or know if it will bear any resemblance, however remote, to the initial color.
Photos of modified Siemens star provide clinical examples of how moire depends on various settings, including rotation angle.
