Hello, newbie here. I've read through many of the forums, and I'm getting ready to purchase my first Alpha and could use some advice. My needs are for a low light body, as I usually shoot indoor music (stills) in small dimly lit club environments. I've done a bit of homework but on the fence choosing between an A7III vs A7sII. Are these my best choices for low light shooting ? Don't have the budget for the A7sIII.....I will likely not be shooting any video. Any input and advice appreciated ! Thank you
