So Jens Peermann is like me, looking to lighten the load. I love my Canon G11 and keep it in the car. It is so easy to use, and has an articulated screen. For telephoto or challenging light, it is not so good. I am spoilt by my Canon 5D Mk3 with L lenses, but time has moved on. I am not sure I need full frame any more. It now seems that APS-C sensors can be well into the 20MP+ range, and even 1" are up to 20MP. Of course, though, light has to get through the lens first.
Comparing Canon and Fuji, my 70-200 f4 IS L Canon is 180grammes (over 6oz) heavier than my Fuji 55-200, and even heavier with the 1.4 extender. I am happy with the 55-200, albeit with a body with 16MP, but have not done detailed pixel peeping. Other Fuji lenses, especially primes, seem very good to me. One reason is that the majority of my images are now viewed on an iPad or published in a magazine at a maximum of 9 inches on the long side so I do not need loads of pixels except if I need to crop.
The upshot of this is that I read Michael's review with great interest, but in the respect of lightening the load (as others also want to do) I am looking for comments on lens & camera body weight and IQ, to minimise the former and maximise the latter.
