GH5: setting for churches with low light? Only candlelight.
 

Hello, the next months I will go to make a short documentary in the Coptic churches with poor light.The churches at night lit up little more than with candlelight of many faithful. Can anyone advise me how to configure the GH5 to get a good video inside the churches? I have the Leica 12-60mm f / 2.8 lens.
Outside I want to film in 50p but maybe inside it would be better to film in 25p to get more light. Quite right? Thank you.
