Here's a hands on video of the UX90 that I found.

From reading the brochures, it looks like the UX180 and HC-X1 use the same sensor, while the UX90 uses a different one. The sensors on the UX180 and HC-X1 both have 8.79 Mpixels for UHD and FHD modes, and 9.46 Mpixels for 4k mode. But the sensor on the UX90 has 17.78 Mpixels for FHD mode, and only 8.59 Mpixels for UHD mode. So the UX90 significantly crops the sensor when going from FHD to UHD (similar to what the DVX200 does, but the DVX200 has a larger sensor). This is also confirmed by the lens, which has a (35mm equivalent) wide angle focal length of 24.5mm at FHD, but 35.4mm at UHD. On the other hand, the UX180 and HC-X1 uses the full sensor for 4k, and slightly crops for UHD and FHD. This is also confirmed by the lens that goes from 24mm at 4k to 25.4mm at UHD and FHD.
So in my opinion, the UX180 and the HC-X1 are the two cameras that should be classified in the same family, while the UX90 should be in a different family. But who am I to say? :smile:
So it seems like the noise performance when shooting 4K should be better for the UX180 compared to the UX90. And given the specs, it seems like the two cameras probably have different sensors (not to mention different lenses), so the UX90 and UX180 may end up performing quite a bit differently.
I hope for that, because I was waiting for a lot of months to choose between UX180 & Sony Z150. If performance of UX180 is the same, I will choose Z150 (with all the limitations that it have).
The UX180 is about a full f-stop faster, and has a much wider FOV when shooting UHD...
the UX180 I saw was a very very early prototype


That's what I was afraid of.
Anyone knows if this is compatible with 256GB SDXC cards? On the specs, I only see up to 128GB.
SDHC Memory Card : 4 GB to 32 GB
SDXC Memory Card : 48 GB to 128 GB
This unit is compatible with UHS-I UHS Speed Class3 standard SDHC/SDXC Memory Cards.
MOV/MP4 > VFR Mode, 100 Mbps > UHS Speed Class3
MOV/MP4 > 50 Mbps > UHS Speed Class1 or more, Class10 or more
AVCHD > Recording function or Recording format : All -> Class4 or more
But [the DVX200] works just fine with 256GB cards, so I would be surprised if the UX90 and UX180 were any different.
Got to check out the UX180 at NAB NY. Panny had an "engineering" model on display. The 180 appears to be okay, not great. Compared the 180 to the Sony Z150. Preferred the Z150 LCD display. It was brighter, contrastier, and appeared sharper.
