Moire on the Z90, curious if this is normal.

I just got in some footage from a recent shoot on the z90v and noticed some pretty fierce Moire.

It was shooting in 50mbs XAVC-L (1080). Is this to be expected from this camera? I was expecting the same image quality as the FS5, but maybe I was hoping for a little too much from this camera.

You could try the following. In the DETAiL menu you can try going into MANUAL SET and turn it ON. Now set the B/W BALANCE to TYPE1. This will help minimize the detail enhancement between high contrast edges, sharp high to low luminance transition edges. Also the V/H BALANCE can help by going to a positive value as this will minimize vertical detail which can be a contributor to moire artifacts. Also you can play with the LIMIT settings as this will determine how much you want to limit the overall detail. Higher numbers indicate less detail limiting. See pages #138 and 139 in the manual. Moire is a frequency based artifact and by changing fine detail resolution levels you are changing their sampling frequencies and in turn this can affect both aliasing and moire to varying degrees. The old story of suck it and see how it goes.

I haven't seen moire like that with my Z90, what were your paint menu settings?

I will give this a shot and do some test shots tomorrow, thanks for the info.
