I shoot a lot of concerts in dark with an fx3. Do you think the Sony being at f4 compared to the sigma would still be more than fine with the fx3s great low light features.
Honestly, that extra stop of light makes a big difference for keeping the iso low But honestly that camera is so kick ass I don’t see why you would have an issue with the f4 form the Sony camera
Just use 12800 ISO if you are shooting a7siii. I do about 50 houses a month I’ve never shot below f5.6 mostly f8 on video at 12800 ISO. It’s just as clean of footage with the same dynamic range on the sensor.
please use a lav mic. audio is bad. otherwise enjoyable, except your wb. too cold. bring wb balance down. lower some body fat, youll look good. you have a good frame. lets do deadlifts together.
