🧱 Build and Handling
The Sony A7C offers a familiar Sony E-mount full-frame experience in a much more compact body than traditional full-frame hybrids. It has a decent grip for its size, IBIS built in, and performs well for handheld and travel use.
The Lumix S9 further pushes the compact agenda: it’s very lightweight, has a simplified control layout aimed at creators, and emphasises portability and ease-of-use in hybrid workflows.
👉 Verdict:
-
A7C: Best for those who want full-frame quality in a compact body with a bit more “traditional” stills-camera feel.
-
Lumix S9: Better for creators prioritising lightweight carry, video workflow, and content-first design.

A7C: Very dependable autofocus for stills and decent for video in its class.
-
Lumix S9: Slight edge if you prioritise latest AF features and video-centric subject detection — especially for hybrid content.
