How about the 990? Any users?
 

Just saw the 991 on BH and see it is called the 990 in the UK (where it is around 700 pounds). Has anyone tried it yet?

The UX-180 looks fantastic but I need a 4k in late August so it won't be available. The other option is just to stick with the FZ1000 and its 1" sensor but the IS when it is on 4k is not that great. I am hoping a dedicated video cam will have better IS than one made for still photography.

As this is for wildlife photography the more zoom the better.
