Like you, I keep looking for something which can serve all my needs. Haven't found it, except possibly the FZ1000 and that is no lightweight. Perhaps Olympus is the go.I recently rented a Lumix GX8 and Lumix 12-35 f/2.8. A nice combination with good IQ, but it was as large as my Fuji X-E1 + Rokkor 24mm combination. I've pretty much given up on my "one lens for all" idea. That's why I originally rented the Lumix duo - to see if it was something that could replace all my gear. In a word - No. My X-T1 and a pair of small lenses fit neatly into my small sling bag. The weight is negligible. I like Fuji, but they are doing like so many other companies - making things bigger. The X-T1 is smaller than the X-T2 and X-Pro2, and the X-H1 to be announced soon is supposedly even bigger. The Oly E-M5 + 17mm f1.8 was a nice, compact combination, and if the stuff I've put on eBay sells, I may just grab the pair again for really compact outings.
I hate it when you go to the beach and have to deal with a lot of interference.The photon goes to the beach and takes two photos of the waves crashing on the rocks: one at a fast shutterspeed, and one at a slow shutterspeed. After having the roll developed (ours is a hipster photon), the photon sees two identically black photos.
