Verdict: The Lumix S5 II wins overall due to its full-frame sensor providing 1-2 stops better low-light performance and dynamic range per DXOMARK scores. The G9 II counters with a lighter body and unique 100MP handheld mode useful for landscape work. Both share phase-detect AF and strong video specs but the S5 II's active cooling supports longer 6K clips without overheating.
Winner: Panasonic Lumix S5 II
