Some thoughts: Identical sensor. More buttons on the A7iii, although IMHO one doesn't need them as much on the A7c. AF in the A7c is uncanny and feels like cheating at times, although the A7iii's no slouch either. EVF bigger on the A7iii, but the flippy screen in the A7c is more useful. Bigger lenses feel a lot more at home on the iii. I'd go with the one that feels better to you in your hands. Answer from Commanderbrot on reddit.com

r/SonyAlpha on Reddit: A7C vs A7III?
January 11, 2023 -

Hi!
So I am stucked between these two machines and I don't know which one to get..

My mainly goal is the A7IV but that is for the future. For now I have to choose between these two but I just can't. One minute I think the C is better then the III and vica versa...
I am a beginner who's coming from M43 Lumix G9.

I will use it for photo for 70% of the time and 30% for video. In the long game I hope I will be a professional and want to make a living from it, but as for now I just want to shoot. :)

October 6, 2020 - I have the Sony A7RIV and a lot of full frame lenses.

August 11, 2022 - For the first time since the launch of the original A7, Sony has introduced a fifth model name and this time, it’s not about what is inside, but the how it looks on the outside. I wish I could tell you that the A7C has a completely new look, but instead Sony has taken the design of its APS-C cameras and fit a full frame sensor inside.

Sony a7C Versus a7 III: 16 Important Differences | Fstoppers
October 16, 2020 - However, Sony released another camera this year which is curiously placed: the Sony Alpha a7C. It looks on the face of things to be the a7 III lite, with its smaller dimensions and ergonomic alterations. However, there isn't a great deal else in the way of spec sheet differences at first glance, and at almost the same price, you could be forgiven for wondering what sets the two apart.

May 26, 2021 - Not everyone has the resources necessary for the top of the line A7SIII. But if you were willing to give up some features like a second card slot and top tier low light (the A7c and A7III are just fine in low light for me) the A7c gets some of the best A7SIII upgrades that older Sony models like the A7III do not possess:
