Sensor and Image Quality: Slight Differences with Big Impacts
At the heart of any camera lies its sensor, and this is where the S1II and S1IIE start to show their differences. The LUMIX S1II is equipped with a 24.1MP full-frame, partially stacked CMOS sensor, which enables faster readout speeds and reduces rolling shutter effects during high-speed video recording. This sensor design allows it to handle 5.1K 60p and 4K 120p recording with ease, making it particularly well-suited for action photography and high-resolution video work.
On the other hand, the LUMIX S1IIE carries a 24.2MP sensor inspired by the LUMIX S5II. Although it offers slightly more resolution, its architecture is more traditional compared to the partially stacked design of the S1II. Despite this, it excels in 6K 30p open-gate video recording and introduces a Cinemascope (2.4:1) format that’s perfect for cinematic projects. The S1IIE also boasts 14+ stops of dynamic range in V-Log, slightly under the S1II’s 15 stops in Dynamic Range Boost mode, but still impressive for demanding video work.
Video Capabilities: High Frame Rates vs. Cinematic Flexibility
When it comes to video, both cameras are powerhouses, but they approach it differently. The S1II stands out with its 5.1K 60p and 4K 120p capabilities, along with 5.8K 60p options. This makes it ideal for high-resolution slow-motion footage and flexible post-production cropping. Its Dynamic Range Boost mode ensures up to 15 stops of dynamic range, providing rich detail even in challenging light conditions.
The S1IIE, while slightly behind in frame rate options, offers something unique with its 6K 30p (3:2) open gate recording. This format captures more vertical information, giving filmmakers additional room to reframe shots in post. Its Cinemascope (2.4:1) mode, available at various frame rates up to 60p, is a standout feature for those looking to achieve a true cinematic look without cropping. For videographers leaning towards storytelling and film-like quality, the S1IIE’s offerings are quite compelling.
Autofocus and Shooting Speed: A Close Match with Minor Differences
Both the S1II and S1IIE share Panasonic’s enhanced Phase Hybrid AF system, complete with AI-driven tracking for face, eye, and even Urban Sports movements like skateboarding and parkour. This new mode is a nod to Panasonic’s commitment to action and street photographers who need reliable autofocus in unpredictable scenarios.
In terms of shooting speed, the S1II pulls ahead slightly with 70 fps electronic burst shooting. It also supports a 1.5-second pre-burst capture, which means it starts recording images before you fully press the shutter. This is particularly useful for sports and wildlife photography, where timing is everything. Meanwhile, the S1IIE offers a still-respectable 30 fps burst rate, which should suffice for most scenarios but falls short of its sibling’s rapid-fire capabilities.
Design, Stabilization, and Workflow Enhancements
From a design perspective, both cameras are built with Panasonic’s hallmark ruggedness—capable of operating at –10°C and featuring a 5.76 million-dot EVF along with a 1.84 million-dot free-angle LCD. Both models are fitted with 8-stop in-body image stabilization (B.I.S.) and cropless electronic IS, which ensures steady shots even in handheld scenarios.
When it comes to workflow, Panasonic has focused on seamless integration with tools like Capture One for studio photography and Frame.io for cloud-based video collaboration. Both cameras also support ProRes RAW recording (5.8K 30p and C4K 60p) and ARRI LogC3 for advanced color grading, enhancing their appeal to professional filmmakers.
Conclusion
The LUMIX S1II and LUMIX S1IIE both represent significant steps forward for Panasonic’s full-frame lineup, but they cater to slightly different audiences. The S1II shines with its high frame rates, stacked sensor, and superior dynamic range, making it perfect for action photographers and fast-paced videographers. Meanwhile, the S1IIE focuses more on cinematic storytelling with its 6K open-gate recording and Cinemascope format, positioning it as an excellent choice for filmmakers.
Both models are expected to be available starting late June at Panasonic’s authorized channel partners, ready to elevate the creative possibilities for professionals and enthusiasts alike.
