The weak link...I use a Mophie battery tethered to the camera and have power for thousands of images.

I don't think I can cope with shooting while on that thing but it's a very good option to charge it on the field.
I know it's a better travel camera than what I have right now, a Panasonic FZ1000. Tha Pana I bought to be used mostly as a car camera, to be ready for anything the road throws at me but I never really liked it. The lens while not the sharpest it is serviceable (Sony seems sharper on the wide end, just a little more on the long end) and the focus is ok albeit a little slow at the long end; what I really dislike is the colors. Lots of work to get something ok. I got some nice shots with it but I processed them in B&W.
Now I have until tomorrow to decide if it's really worth this improvements (so it arrives in time for a Washington DC trip). The 300g extra it's significant but the volume seems to be close so I can accept that particularly as I enjoy shooting telephoto .
As a landscape camera I'm still not convinced, partially my question regarding corners.
In good conditions the sensor is ok (based on the experience with RX100 and FZ1000, which are close IQ wise) but it's not as easy to deal with it if light is not as nice. I know some are happy with ISO 3200 on it but I have problems with the same ISO on m43/APS-C. For the same weight I also would trust more an E-M1ii with the 12-100 F4 for rough conditions (backpacking).
PS. the Pana colors are probably a lot the Adobe fault as there is no camera profile for it.
