I was lucky to have received a test unit of the Panasonic UX90 ( UX 90 ) camcorder. As you can see on my channel, many of my videos have been shot with the AC90 that I got back in 2012. I decided to compare the low light abilities against each other. The UX90 actually has an even higher gain setting but I only did up to 30 since that's the limit of the AC90.
The UX90 is 1 of 3 new professional 4K camcorders from Panasonic. The other 2 is the UX180 ( UX 180 ) and the HC-X1 ( HCX1)
If my videos get enough attention, I'll get to borrow the UX180 next. That camcorder can do 4K60p!! I have a lot of cool ideas for it.
As you can see, the price of the UXX90 is $2,096 http://amzn.to/2gjeHyG
When the AC90 first came out it was $2,000 and then soon after that, it got down to $1,800 on special. With the $200 I saved, I ended up getting a camera bag.
This is my first video of the UX90 and I'll be posting a heck of a lot more videos, including tests and different events such as Lion Dance competitions in Boston, opening ceremony of the frog pond ice skating rink and Holiday events around Boston. I'll also try to shoot a music video with it.
Compared to my AC90, it has a built in lens cap, strong ND filters (AC90 has them but would still need an extra ND filter for outdoor shooting or the shutter would be a bit on the high side), longer zoom lens and obviously shoots in 4K 24p and 30p.
It has a 1" chip and so that would in theory make the auto focusing worse than professional cameras with smaller chips but with the brief moments I had with it, it's actually pretty decent. I've only tried inside the house and a tiny bit outside the house. With the AC90, the auto focusing is extremely good in that in many situations, you don't need to manual focus. We'll see how the UX90 does.
It has a hybrid stabilizer but unfortunately that only works with the HD modes. With the 4K mode, it's just an optical stabilizer. Maybe it'll work with the UX180 or HC-X1 because it supposedly uses more pixels for 4K. Speaking of using more pixels for the video, the UX180 is said to be better at low light capabilities are is a little sharper. If the HC-X1 is using similar tech as the UX180, it'll be sharper than the UX90 as well. Both the UX180 and the HC-X1 have 4K 60p and a 20x zoom lens. The UX90 is at 15x. Still a big price difference. UX90 is $2,095 while the HCX1 and the UX180 is $3,199.99 and $3,495 respectively.
