Sony FX5 vs. Panasonic S1 II: Is Cinema-First Worth $1,700 More?
The Sony FX5 costs $1,700 more than the Panasonic S1 II. Here's what that premium actually buys, and whether it's worth it.
The Sony FX5 and Panasonic S1 II both record internal RAW video and sit in roughly the same conversation for hybrid and cinema shooters, but they come from genuinely different starting points. The FX5 is a dedicated cinema camera; the S1 II is a true stills-and-video hybrid. That difference in philosophy explains almost every spec gap between them, and the roughly $1,700 price difference that comes with it.
Two Different Sensors, Two Different Priorities
The S1 II uses a 24.1MP full-frame partially stacked sensor, meaningfully higher resolution than the FX5's 16.6MP full-frame stacked sensor, and that resolution advantage carries over to stills work the FX5 was never really built for. The S1 II also offers a 96MP high-resolution stills mode, something entirely outside the FX5's design intent.
The FX5's stacked sensor still holds its own on the video side, offering 5K Open Gate capture and faster readout that keeps rolling shutter in check. The S1 II answers with its own strong numbers: 5.9K at 60fps, 4K at 120fps, and open gate recording up to roughly 6K.
RAW Format Is the Real Philosophical Split

This is where the two cameras diverge most. The FX5 records internal 16-bit X-OCN RAW, Sony's own proprietary format built specifically around its own ecosystem and color science. The S1 II records internal ProRes RAW, Apple's widely adopted, industry-standard RAW codec supported natively across a much broader range of editing software without needing dedicated plugins or conversion steps.
Neither approach is strictly better, X-OCN is tightly integrated with Sony's own tools, while ProRes RAW trades some of that tight integration for broader compatibility. But for shooters who value editing software flexibility over ecosystem lock-in, the S1 II's format choice is a real practical advantage.
Autofocus Has Gotten Much Closer Than It Used To Be
Sony has long held a clear autofocus advantage over Panasonic's video-oriented cameras, but that gap has closed significantly. The S1 II's Phase Hybrid AF system, enhanced by AI-based subject detection, saw a substantial firmware improvement in a January 2026 update, described by DPReview as delivering markedly better real-world tracking performance. The FX5 still carries Sony's more mature, longer-refined autofocus lineage, but this is no longer the lopsided advantage it once was in a Sony-versus-Panasonic comparison.
Stabilization and Body Design
The S1 II's 8-stop 5-axis in-body stabilization is genuinely excellent, gimbal-like smoothness for handheld work even with slower lenses, something the FX5 doesn't emphasize nearly as heavily given its design assumption that serious productions will rig or gimbal-mount the camera regardless. The S1 II uses a traditional DSLR-style body with a built-in EVF; the FX5 keeps Sony's compact camcorder-style body with an optional, detachable OLED viewfinder instead.
Competitive Context

At $3,199, the S1 II undercuts the FX5's $4,899.99 body-only price by roughly $1,700, and it does so while offering higher resolution, industry-standard RAW, and excellent stabilization the FX5 doesn't match. What the FX5 sells instead is a cinema-first design with no stills-menu clutter, deeper video-specific tooling, and Sony's still-slightly-more-refined video autofocus tuning, plus the ecosystem pull of Sony's broader Cinema Line for anyone planning to move up to a Burano or VENICE later.
The Signal in the Noise

This comparison really comes down to whether you need a camera that's exclusively built for video production, or one that genuinely excels at both stills and video without meaningfully compromising either. The S1 II makes a stronger case than it would have a year ago, largely because Panasonic closed the autofocus gap through firmware rather than new hardware. The FX5's premium buys focus and ecosystem, not necessarily better raw capability.
If you never touch stills work at all, does the FX5's cinema-first focus justify the extra $1,700, or does the S1 II's hybrid flexibility make more sense for how you actually work?
