Originally posted by zosxavius It also quickly ramps up to f5.8 at the long end. The LX7 shows better bokeh and separation at f2.3, while managing to keep the ISO lower than the sony because it is much faster. I've also read that the sony is not particularly sharp at the wide end of the range as well, but hey...I'm sure its just sample variations and zeiss can make an optically perfect f1.8-5.8 zoom that is razor sharp throughout its range across the whole frame at any aperture. Riiiiight.
Sony RX100 review | Cameralabs
The RX100 would have to be much larger to have an equivalent lens. Look at the G1-X. Slow and hard to get bokeh out of at all, despite its larger than m4/3 sensor. Most small enthusiast P&S cameras end up getting used to take pictures of people mostly. A fast lens on a smaller sensor that allows some dof control at its longest end is a lot more useful than a huge sensor with a slow lens IMO.
EDIT: OK I looked at some samples and the rx100 lens is pretty sharp even at wide end. It has some edge issues there, but really is looking decent in terms of sharpness. Fine detail looks like it was rendered with watercolor though. I'm not impressed with IQ on a pixel level at all.
I don't know where you are getting your info, but you are wrong on a lot of counts.
First off, the max aperture at the telephoto end is f4.9, NOT 5.8.
Second, you criticize a camera's IQ, before looking at samples? Seems like you've made up your opinion based on heresay, then are distorting reality to match your initial viewpoint.
If you look at this thread on this very forum, you will see that IQ is hardly lacking:

Not saying that the RX100 is the perfect camera, but the IQ is generally regarded as tops in its class.
