Panasonic Lumix S S1R II Black 2025
The 44.3MP full-frame CMOS sensor powers 8K 30p and 4K 120p 10-bit video, backed by a 779-point phase-detect autofocus system. Its 710g body—25% lighter than the S1R—is weather-sealed and offers 6.4K open gate recording for flexible framing in hybrid shoots. This camera suits sports and wildlife photographers needing 40fps mechanical bursts and reliable subject detection, plus wedding videographers capturing high-resolution stills and video.
