Is the sony e 15mm f 1 4 g good in low light?
Yes, the Sony E 15mm f/1.4 G is a good choice for low light. It's a fast prime, and f/1.4 gathers far more light than any kit zoom, which is what matters when the lights go down. On APS-C it frames like 22mm on full frame, so it suits indoor scenes, street and food. Its depth of field is about what f/2.1 gives there, so you get some background separation without going razor-thin.
It isn't stabilised, so keep your shutter speed up in dim rooms. It fits APS-C bodies such as the Sony a6400 and the Sony a6700. For the full lens details, see the Sony E 15mm f/1.4 G page. If you're weighing whether full frame would help more, the sensor sizes guide explains when it's worth the extra cost.
