Interesting but I guess that is precisely where you would expect to find it. It would be even more interesting to know whether the original K5 would have had it too as I found some moire in in one of my K5 pictures before I got the IIs. I found that by tweaking the colour channels a bit I could minimise the moire but did not succeed in removing it entirely. On the other hand you have to print quite large and look very closely before you would notice it.

It has to be the right frequency to find moire, and senn has hit an example there for sure.

A smaller aperture, introducing less definition because of diffraction, will lessen the effect. However, this is clearly an area with many variables.

I think we can say that most of the time moire isn't a problem. I haven't noticed it on any of the AA-filter-free cameras I have used, from any marque.

Is the shot showing the moire (2nd shot) a 100% (1:1) crop
and is it from a JPG or RAW?

Thanks. I wonder if it's anything to do with the colours
being basically B&W in that area.
