This topic is of great interest to me, however my dilemma may be even worse: I'm not into macro stuff and can't stand super wide/fisheye*. Guess I would be a "mid-range" kind of photographer, and so far I haven't found a solution to do that in full frame.
My RX100 mk1 is starting to be a limiting factor to image quality, but I just don't see where to upgrade: the bigger the sensor, the less flexibility I seem to find in the mid-range focal lenghts
* Still not convinced I'm a heretic? I dislike nudibranchs! Ha!
