Panasonic S1H vs Sony A7R IV: The Ultimate 2024 Full-Frame Mirrorless Showdown

Choosing between the Panasonic Lumix DC-S1H and the Sony Alpha A7R IV is a classic conundrum for photographers and video creators seeking pro-level full-frame mirrorless cameras. Both arrived around the same time in 2019, but they serve different masteries and mindsets. Having extensively tested both over several months, I’m here to give you an honest, in-depth look at how these beasts stack up, from sensor tech to ergonomics, from autofocus to video chops, and ultimately, which one deserves a spot in your kit.

Whether you’re a traveling portraitist on a budget, a pixel-peeping landscape fanatic, or a hybrid shoot-and-edit storyteller who demands the best of both worlds, this comparison will give you the nuts, bolts, and real-world insights only hands-on experience can deliver.

Getting to Know the Contenders: Quick Specs Overview

Now that we have the "lay of the land" covered, let’s dive deeper into what really separates these two powerhouses.

Body, Build, and Ergonomics: Is Bigger Always Better?

Starting with the physical gear feels appropriate because the S1H and A7R IV look like distant cousins in size and handling. The Panasonic S1H is a much bulkier and heavier camera - over 1kg on the scale - thanks in part to its robust SLR-style design and generous handgrip. This translates into excellent handling stability - especially for video rigs or extended shooting sessions where weight helps steady the shot without strain.

The Sony A7R IV, by contrast, trims the fat at 665g and a slim 78mm depth, leaning into the mirrorless ethos of portability. This makes it an excellent choice if you travel a lot, shoot street photography, or prefer a lighter load without sacrificing pro-level durability.

The Panasonic also goes full pro with weather sealing and a solid magnesium-alloy chassis, defending well against moisture, dust, and the odd bump. Sony matches this toughness but sacrifices some grip size for the sake of compactness. For me - someone who shoots landscapes on a tripod all day and sometimes vest-pocket street candids - the S1H’s bulk isn’t a deterrent; it’s welcome muscle. But if you’re a run-and-gun or multi-discipline photographer, Sony’s leaner frame might be more your speed.

Both cameras sport intuitive top-plate layouts, but Panasonic's S1H features more tactile, illuminated buttons and customizable dials - perfect if you want glove-friendly operation or prefer physical controls over menus. Sony’s design is cleaner, minimalistic even, with fewer clubs for thumbs but enough layout tweaks to keep pros happy.

Sensor and Image Quality: Pixels Versus Filmic Freedom

The biggest difference here is the sensor resolution and design philosophy. The Sony A7R IV boasts a whopping 61.0MP BSI-CMOS sensor - the highest resolution you’ll commonly find in a full-frame mirrorless to date. This sensor has no anti-aliasing filter, allowing extremely sharp, detailed files ideal for landscape, commercial, and studio photography where every micron counts. Importantly, it achieves this while maintaining excellent high ISO performance, thanks to backside-illumination (BSI) technology which improves light-gathering efficiency.

By contrast, the Panasonic S1H has a more modest 24MP CMOS sensor with an AA filter, which some pixel-peepers may consider “low-res,” but it’s perfectly adequate for most pros and enthusiasts. What the S1H sacrifices in still resolution, it compensates in video capability and dynamic range. Its native ISO range peaks higher on paper (51200 native ISO, boosting to 204800), leaning into extremely low-light flexibility for filmmaking and night shoots.

Image quality testing back-to-back shows that the Sony’s 61MP files are glorious for large prints and aggressive cropping. The colors deliver rich vibrancy with deep tonal gradations thanks to the sensor design and Sony’s color science improvements. The Panasonic matches the Sony’s color depth well but benefits from a slightly more natural skin tone rendering - possibly related to its full L-mount ecosystem lenses optimized for neutral colors. It's also helpful that S1H supports multiple aspect ratios from 1:1 to 16:9 natively, aiding creative flexibility.

In short: if ultra-high resolution and pixel-level detail are king for your workflow, the Sony is the clear winner. If you're a hybrid shooter or primarily focused on storytelling via video with solid stills, Panasonic’s sensor is approachable but powerful.

Hands-On Autofocus: Precision and Speed in the Wild

The Sony A7R IV’s autofocus system is genuinely impressive. It boasts 567 phase-detection AF points covering about 74% of the frame - coupled with advanced algorithms that now feature animal eye-detection and sophisticated subject tracking. This makes it a stellar option for portrait photographers hunting for tack-sharp portraits, wildlife snipers in unpredictable movement, or anyone needing assured focus in complex scenes.

Meanwhile, Panasonic’s S1H uses contrast-detection AF only (no phase-detection pixels), with 225 focus points. Despite this seeming disadvantage, Panasonic’s “Depth From Defocus” technology keeps autofocus snappy and accurate during video primarily, but it can feel a touch slower or less reliable in stills compared to Sony, especially in low contrast or low light scenarios. Crucially though, Panasonic lacks animal eye-detection autofocus, which is a big deal in wildlife and pet photography. Face and eye detection work well for humans but can leave users wanting more in dynamic autofocus.

From my experience, the Sony edges out Panasonic by a mile in autofocus sophistication and flexibility. Sony gets my vote for sports, wildlife, and fast-action photography; Panasonic works well for slower paced portrait or video-focused shooting where manual override is common.

Display and Viewfinder: Living Through the Screen

The Panasonic S1H sports a fully articulating 3.2” LCD touchscreen with higher resolution (2330k dots), ideal for video monitoring at weird angles. This “selfie” and vlog-friendly articulation is a significant advantage if you’re experimenting with creative framing or run solo on shoots.

On the flip side, the Sony A7R IV’s 3” screen tilts up and down but doesn’t swing fully around, which can limit usability for handheld video or selfies. While touchscreen responsive, it’s less versatile in this regard. Both cameras support touch-to-focus and touch-to-shutter functions, making live view shooting intuitive.

The electronic viewfinders (EVF) are near identical, both sporting 5.76-million-dot OLEDs offering crisp, bright, 100% coverage with a 0.78x magnification. Sony’s EVF refresh is a hair faster, making tracking moving subjects smoother in live-view and video modes.

If you’re primarily a stills shooter, EVFs from both cameras are equally excellent. Video storytellers and vloggers will appreciate Panasonic’s more flexible articulating screen despite the Sony’s superiority in autofocus and resolution.

Real-World Performance Across Photography Genres

Having walked the walk with both cameras across several genres, here’s a breakdown of strengths according to photographic disciplines:

Portrait Photography:

• Sony A7R IV: Edge in resolution leads to stunning skin details and crisp eye catchlights; animal eye AF is a massive plus. The absence of an AA filter means razor-sharp imagery but beware potential moiré with certain fabrics.
• Panasonic S1H: Skin tones render naturally and video mode has excellent face tracking. The 24MP resolution is sufficient but less flexible for cropping.

Landscape Photography:

• Sony A7R IV: The 61MP files provide incredible resolution for ultimate cropping and large prints. Dynamic range (14.8 EV) is excellent, preserving highlight and shadow details.
• Panasonic S1H: Good dynamic range too, but lower resolution limits large print size. The S1H’s weather sealing and ruggedness make it suitable for harsher environments.

Wildlife Photography:

• Sony A7R IV: Superior AF with animal eye detection, fast 10 fps burst, and sharp telephoto lenses available for the E mount.
• Panasonic S1H: Decent AF but limited for fast-moving subjects; 9 fps burst is respectable but autofocus lag complicates action tracking.

The Sony’s lower weight and battery longevity (670 shots vs 400 for the S1H) make it the better all-round travel companion.

Professional Work:
The Sony’s massive 61MP files, comprehensive autofocus, and workflow integration (NP-FZ100 batteries industry standard, USB 3.1) fit studio and commercial pros better. The Panasonic’s ruggedness and video specs appeal to hybrid shooters who gravitate towards video-heavy productions.

Battery Life and Storage: Keeping You in the Game

The Sony A7R IV’s battery life is significantly better, rated for about 670 shots per charge compared to the Panasonic S1H’s 400 shots. In practice, this translates to less swapping chargers or carrying spare batteries on longer shoots. Sony uses the excellent NP-FZ100 battery, which is also common across much of Sony's lineup, easing corridor issues for multi-camera users.

Both cameras offer dual SD card slots supporting UHS-II speeds, crucial for buffering large RAW or high-bitrate video files, with Panasonic explicitly supporting SD/SDHC/SDXC with UHS-II, and Sony mentioning UHS-II compatibility. Panasonic's slots may have slight edge in speed priority, given its video-centric design.

Connectivity and Extras: Modern Conveniences for the Working Pro

Both cameras offer Wi-Fi and Bluetooth, but Panasonic’s S1H does not include NFC, while Sony offers it for quicker pairing. The S1H has micro-HDMI and full-size USB-C but lacks GPS; Sony similarly lacks GPS. Both provide headphone and microphone ports for video audio control.

Notably, Panasonic offers illuminated buttons for low-light adjustment - helping in tough shooting conditions. Sony’s interface can sometimes feel labyrinthine but custom buttons lessen learning curves.

Price-to-Performance: What Do You Get for Your Bucks?

If you’re a cheapskate (or just budget-conscious), the Sony gives more bang for the buck in terms of resolution and stills photography versatility, while the Panasonic demands a premium mostly for its filmmaker-class video feature set.
