LX100 and BMPC look like winners in this contest, not blurring out all the details but showing very little moire.

I guess the GH4 would have performed just as the LX100 did.

One thing we don't know, of course, is whether and how downscaling from 4k was done, and that of course can make a lot of difference.

Nice shootout. I like that the LX-100 looked sharp and moire free. We are getting a lot of good tools from Panasonic.

TO my amazement I got some moire on the GH4 in UHD 4k mode on something I just finished editing (I unfortunately had to shoot & edit it) lol.

I didn't think it was possible, but, here's the proof. Even now looking at it a week later, I had a hard time seeing it, I had to look for it, it doesn't jump out at you. It only happened at a particular focal length, which I didn't stick to for very long. Otherwise, this kid's suit gave me no problems at all.

Shot in CineD & sharpening turned all the way down. Lens was a Panasonic 14-45 at ca. f5.6 That might have been where the extra sharpening came from… If memory serves, the Panny lenses turn on some extra sharpening (I think the test I saw was with a GH2 though).

This is a screen grab of a portion of the 4k frame at 100% size.
