So, what about A6000 + 16-70 f/4 + LA-EA4 (160g) + Minolta 100-200 f/4.5 (375g) ?  The former two are "given", aren't they ? The latter two weight 535g, less than RX10. Everything is top quality, and you are still far away from 20kg bag.

 

I'm trying to reiterate that _you_ will not be satisfied by small-sensor cameras, even if the sharpness is excellent. When you look at a representative number of pictures from small sensor camera, even if they look technically perfect, there's a feel of something wrong with them. It's hard to explain. The best known to me attempt to do so was by David Kilpatrick; he wrote that if you shoot doll house with small sensor camera, it appears realistic, and dolls look like humans.

 

 

Sorry but I am already perfectly fine with MFT quality. I have a GH3 which produces great results.

I am a non-believer in ancient lenses so something like the Minolta 100-200mm will not happen on my side.

Technically the Canon EF-S 55-250mm STM IS could be interesting (using the Canon AF adapter).
