Started free-lancing during covid and have saved up some money. Right now I have a M4/3 and even though I love it I want to change to full frame before it’s too late.

I shoot mostly which is why I’m leaning more towards the A7S but I was wondering how’s the still image performance. I do a bit of food photography and am trying to get a bit into modeling photography etc.. so I’m wondering if the A7IV would be better for my needs if I want to do both.

I am lowkey already sold on the A7SIII thoo ive seen what it’s capable of especially in low-light (which is what I usually work with) and it’s a fucking beast. I am honestly just wondering how good are the stills ?
