Panasonic's Lumix S1H successor has been one of the most anticipated cameras in the professional video community, and new reports in June 2026 reveal that the camera's development is essentially complete — with the sensor being the final piece of the puzzle. According to sources within Panasonic's imaging division, the company has narrowed the sensor choice to two options, each with significant implications for the camera's market positioning.
Option A: 24MP Stacked Sensor
The first option is a 24MP backside-illuminated stacked CMOS sensor, likely sourced from Sony or developed in partnership with Tower Semiconductor. This sensor would deliver dramatically faster readout speeds than the original S1H's 24MP BSI sensor, enabling 6K 120p internal recording and significantly improved rolling shutter performance. For filmmakers who prioritize frame rates and low-light capability over resolution, this is the ideal choice.
Option B: 44MP High-Resolution Sensor
The second option is a 44MP sensor similar to the one found in the Lumix S1R II, but with video-optimized readout circuitry. This would make the S1H successor a true hybrid camera, capable of delivering 44MP stills alongside 8K video. The trade-off would be slightly reduced low-light performance and slower frame rates at maximum resolution. For photographers who also shoot video — wedding shooters, for example — this option is compelling.
Panasonic's Dilemma
Industry analysts believe Panasonic is leaning toward Option A — the 24MP stacked sensor — for several reasons. First, the S1H's reputation was built on video performance, and a high-resolution sensor could dilute that identity. Second, Panasonic already has the S1R II for photographers who need 44MP. Third, the 24MP sensor's faster readout enables features like 4K 240p and improved Phase Detection AF, both of which are competitive necessities in 2026.
When Will We Know?
Panasonic is expected to announce the S1H successor at IBC 2026 in Amsterdam this September. The timing makes sense: IBC is Europe's largest broadcast and media technology show, and Panasonic traditionally uses the event to showcase its professional video products. If the camera ships by November, it will be available for the holiday production season and the 2026-2027 winter sports calendar.
Bottom Line
The sensor decision will define the S1H successor's identity. A 24MP stacked chip would make it the ultimate video-first Lumix, while a 44MP sensor would create a more versatile hybrid. Either way, Panasonic needs this camera to succeed — the S1H's legacy as a Netflix-approved cinema camera sets high expectations for whatever comes next.
