Re: LX7 - does its IQ compete with e.g. Sony RX100? depends on one's expectations

Dunno, I don't have either, but these specs are intriguing:

LX7:       298g, 110x68x46mm, 1/1.7" (7.44x5.58mm) sensor, 10mp, 24-90mm efl.

RX100:   240g, 102x59x36mm, 1" (13.2x8.8mm) sensor, 20mp, 28-100mm efl.

One might say that the Sony's sensor area/weight ratio is impressive.


it's all relative, and harder to judge without 'exemplar/benchmark/reference' points or 'context'

comparing 'big-body-big-sensor-big-pixels' on downwards towards to smaller and smaller till one has the opposite extreme of 'tiny-body-tiny-sensor-tiny-pixels' (and ergonomic compromises in exchange for 'pocketability')

ISO 6400 [worst possible to expect on your examples]:
5DMkIII (FF) vs PowerShot G1X (1.5") vs CyberShot RX-100 (1") vs Lumix LX7 (1/1.7")

it all depends on what you shoot, and what your tolerance is for noise vs NR distortion or smoothing vs fine details intact

at least the RX100 NR is 'smooth' even if sacrificing obscuring details at higher ISOs in lower light; whereas the LX7 is 'mottled' and noisy.
