Is the sony fx3 good in low light?

Yes. The Sony FX3 uses the a7S III's full frame sensor, which is built for video and low light. Full frame gives you roughly one stop of advantage over APS-C at the same framing and f-number, as explained in what a bigger sensor buys you. The FX3 also has in-body stabilisation, which helps when you're shooting handheld in dim rooms.

Low light depends on the lens as much as the body, so look for wide apertures. Good options from the FX3 list include:

• Sony FE 24mm f/1.4 GM for fast, wide scenes
• Sony FE 50-150mm f/2 GM for fast zoom coverage
• Sony FE 24-70mm f/2.8 GM as a fast everyday zoom
