With zone plates and a good lens you can provoke color moiré on just about every Bayer sensor. I can see that with a Red or an Alexa too, which are both using rather conservative OLPFs. Sony was notorious for massive moiré, even if they had OLPFs, but from what I hear the Venice is doing better (I didn't test that one myself). No manufacturer would try to completely filter that out with a Bayer sensor, since it would reduce perceived resolution too much, which is mainly based on luminance.
I'm very impressed what BM achieved here with their new sensor, showing next to no color moiré in the test charts. And then, we can clearly see that only the best lenses are provoking some luma moiré. In John's test, only one of the two lenses is clearly showing it, the other is too soft to trigger obvious moiré.
I'd doubt it would be any problem with real-world footage,and, believe me, I'm critical regarding moiré. I hated it on my old BMPCC, I could see that it was far less with our UMP 4.6K with more than twice the resolution, but I still got us a RAWlite for that one. I don't think I'd need an OLPF for an UMP 12K, even if I'd feed the light from my Zeiss 60mm macro, which is razor sharp.
@John: Would you mind telling us which lenses those were?
Now that the cat #19 is out of the bag, test it as much as you can and use the subforum.
