I haven't had Q for long time yet but here are some full size samples with 02 zoom, so judge yourself (click image for full size). Shot DNG and exported from Lightroom with some levels/contrast and sharpness adjustments:
5mm, ISO 500
6,6mm, ISO 640
7,3mm, ISO500
8,5mm, ISO 200
11,8mm, ISO 125
14,9mm, ISO 125
And some with 01 prime (click image for full size):
ISO 125
ISO 125
ISO 125
Original RAW file may seem bit soft at first but with some careful sharpening it does pretty good. I haven't tried jpg as I shoot only RAW. I don't know what others think but IMO that's pretty good for small and "bad" sensor
But of course small size comes with a price as the details start to fade rapidly at ISO 800 and forward.
