The full-frame L-mount camera is the first to use a 44MP BSI CMOS sensor that reads out quickly enough to realize 40fps image capture and 8K video.

Despite being smaller and lighter, the S1RII also introduces faster phase-detect autofocus and improved stabilization.

The Panasonic Lumix S1R II offers almost all of the same core features and specs as the Canon R5 Mark II at a much lower price point. It's video specs and autofocus system aren't quite as advanced, but it does offer a special High Resolution mode, Dual Native ISO, faster shutter speeds and faster 40fps continuous shooting.
