Is the leica q3 good in low light?

Yes, the Leica Q3 should do well in low light. It has a full frame sensor and a fast 28mm f/1.7 lens built in. At the same framing and f-number, a bigger sensor collects more light, so it stays cleaner at high ISO than APS-C or Micro Four Thirds. You can see the full specs on the Leica Q3 page.

If low light and video are your main jobs, the Leica SL2-S is the one I'd look at harder. The site describes it as better suited to both. For why sensor size matters so much after dark, see the sensor guide.
