Here are the first real size comparison pictures between the new Panasonic S9 and the Sony A7c cameras . Notice that the Sony has some room to further reduce the size of the camera due to the smaller mount. Panasonic can’t get smaller than this.

This is where I think the Panasonic outperforms the Sony:

• I like the clean design of the Lumix S9. The A7c has a cheaper look and feel.
• The Lumix has a great IBIS
• OpenGate is super useful
• From what I’ve seen, the APP integration works much better than Sony’s app.

That’s where I think the Sony is better than the Panasonic:

• The A7c series has a built-in EVF (for a photographer this is a must).
• The A7c series has a mechanical shutter
• many more controls on the Sony
• Far better autofocus performance
• Many pancake AF lenses that the L-mount system does not have.
