I'd be happy with just a 24-90mm equivalent lens at wider aperture - not even a super zoom....:)

The the Panasonic LX7 is for you. 'Cause one way to fit a faster lens on a compact camera is to use a smaller sensor. Panasonic LX7 gives you f2.3 at 90mm eq.

But there is little advantage of the faster lens though. LX7's f/2.3 is very close to RX100's f/4.5 at 90mm because of LX7's smaller sensor. OTOH, RX100's f/1.8 at the wide end is actually 1 1/2 stop better than LX7's f/1.4. You can check out dpreview's aperture equivalent table to give you some idea of how the different cameras compare.

How "fast" the lens is may not mean much if you don't take the sensor size into account. The only time that this matters is in DSLR where the AF sensor depends on minimal wide aperture number to work. In case of compact camera, no such restriction exists.
