Is the panasonic lumix s5 good in low light?

The S5 is a full-frame camera, and full frame is the size that helps most in dim light. Compared with APS-C, a bigger sensor gives roughly one stop of advantage at the same framing and f-number, so you can use a lower ISO for the same shot. I don't have a measured low-light score for the S5 on this site, so that's the reasoning rather than a test result.

The lens matters as much as the body here. For dark rooms and night street, I'd look at a fast prime:

If you're new to primes, the lens guide explains why they gather so much more light than kit zooms.
