Panasonic S1 vs Panasonic LX10: A Hands-On Comparison for Enthusiasts and Pros

When it comes to picking the right camera, especially from the same brand but vastly different lines, it’s easy to feel overwhelmed. I’ve spent the better part of my career dissecting cameras in labs and field tests, and the Panasonic Lumix DC-S1 (a pro-grade full-frame mirrorless) and the compact Panasonic Lumix DMC-LX10 (aka LX15) perfectly illustrate a spectrum of photographic possibility. Both come from Panasonic, yes, but each targets distinct photographers with unique demands. Through this comprehensive comparison, I’ll share insights from hands-on testing and deep technical evaluation to help you decide which fits your photographic ambitions best.

Size, Build, and Handling: DSLR Versus Pocket Rocket

Physically, the differences between the S1 and LX10 couldn’t be starker. The S1, built as a professional “SLR-style” mirrorless, boasts a robust magnesium alloy chassis with extensive weather sealing. It weighs in at about 1021 grams and measures roughly 149x110x97 mm. The LX10 is a compact powerhouse, designed to fit in a jacket pocket at only 310 grams and 106x60x42 mm.

In use, the S1’s heft translates to excellent grip stability and a feeling of ruggedness ideal for extended shooting in tough conditions. Its pronounced handgrip and well-placed dials invite tactile confidence for manual control, a must for pros shooting outdoors or events. The LX10, by contrast, slips easily into a pocket or purse, making it eminently travel-friendly and unobtrusive for street or casual shooting. Its fixed lens and minimal external controls keep things simple but slightly limit creative control compared to the S1’s extensive external operation options.

The top plate layout further highlights this divide:

The S1 sports numerous dedicated dials for ISO, shutter speed, exposure compensation, and an OLED top panel for quick info viewing. The LX10 trims down controls to essentials, pleasing those who prefer simplified menus or are upgrading from smartphones and want minimal fuss.

Verdict: If you prioritize ergonomics, weather resistance, and durable build for heavy-duty use, the S1 wins outright. The LX10 shines as a stealthy, pocketable companion.

Sensors and Image Quality: Full Frame Versus 1-Inch Compact

Arguably the heart of any camera is the sensor, and Panasonic’s choices here couldn’t be more divergent. The S1 houses a 24MP full-frame CMOS sensor measuring 35.6 x 23.8 mm, a sizable imaging chip providing a 1:1 focal length multiplier. The LX10’s sensor is a 1-inch BSI-CMOS, about 13.2 x 8.8 mm, with a crop factor of approximately 2.7x.

Testing the dynamic range using industry benchmarks, the S1 scores a stellar 14.5 EV, while the LX10 achieves around 12.5 EV. Color depth also favors the S1 (25.2 bits vs. 22.8 bits). These numbers aren’t purely academic; they translate directly to retained detail in shadows and highlights, especially relevant in high-contrast landscape and portrait sessions with tricky lighting.

High ISO performance is another key differentiator: the Panasonic S1’s native max ISO of 51200 (expandable to 204800) delivers usable images at ISO 6400 and beyond with manageable noise patterns and excellent tonality. The LX10 maxes out at ISO 12800, but ISO 3200 typically is its practical upper limit before noise becomes a distraction.

Sample image sets (captured side-by-side in controlled outdoor and studio scenarios) reveal the S1’s smoother gradations, superior sharpness from larger pixel wells, and better color fidelity at all ISOs:

The LX10’s sensor impresses given its size, producing sharp images with pleasing contrast. The fast f/1.4-2.8 lens is a bright companion for low light. However, one must temper expectations in challenging lighting or when making large print enlargements - noise and detail loss become apparent sooner than on the S1.

Verdict: The S1’s full-frame sensor outperforms hands-down in image quality, dynamic range, and low-light prowess. The LX10 excels as a high-quality compact but is limited by physics and sensor size.

Autofocus and Shooting Performance: Precision or Simplicity?

Autofocus is a critical spec for any camera, especially for fast-paced genres like wildlife or sports photography. The S1 uses a contrast-detection AF system with 225 selectable points, including real-time face detection and tracking. Although it lacks phase-detection pixels native to some rivals, its AF algorithms and Venus engine processor compensate well in both speed and accuracy.

The LX10 offers 49 AF points and face detection but relies solely on contrast-detection AF. Its smaller sensor facilitates quick focusing but isn’t built for demanding tracking scenarios.

Continuous shooting rates underline this divide: The S1 shoots at 9 fps with AF tracking, suitable for capturing decisive moments, while the LX10 reaches 10 fps but without the sophisticated tracking algorithms or buffer depth needed for sports or wildlife.

In real-world wildlife testing at a bird park, the S1 nailed fast-moving birds with impressive focus lock and minimal hunting. The LX10, while responsive, occasionally struggled to reacquire focus on erratic subjects, making it better suited for portraits or static subjects.

Verdict: The S1 delivers a professional-grade autofocus system designed for complex action and continuous tracking. The LX10’s AF is snappy enough for everyday shooting but not for demanding scenarios.

Screen and Viewfinder Experience: Composing and Reviewing Images

Reviewing and composing shots is a tactile area where the two cameras diverge sharply. The S1 features a 3.2-inch tilting touchscreen with 2.1 million dots and an OLED electronic viewfinder sporting a remarkable 5.76 million dot resolution offering 100% coverage and 0.78x magnification. The EVF is bright, accurate, and crucial in bright outdoor conditions where LCD glare hampers visibility.

The LX10 offers a 3-inch tilting touchscreen at 1.04 million dots but lacks any kind of viewfinder, relying on LCD composition alone.

For me, the S1’s EVF is almost indispensable, especially for precision manual focusing and during long shoots where LCD eye relief causes fatigue. The LX10’s absence of EVF is a clear compromise for size, though its touchscreen is responsive and well-calibrated.

Lens Ecosystem and Compatibility: Can Your System Grow?

Panasonic’s Lumix S1 uses the Leica L-mount, shared by Panasonic, Sigma, and Leica. At launch, the L-mount ecosystem already spans over 30 native lenses, covering primes, zooms, and specialty optics. This open ecosystem means users benefit from an expanding range of lenses suitable for portrait, landscape, macro, telephoto, and more.

Conversely, the LX10 sports a built-in 24-72mm f/1.4-2.8 zoom lens with no versatility for changing optics. This fixed lens is sharp and bright, but of course limits flexibility for specialized photography.

For professionals or serious hobbyists, the S1’s compatibility opens creative doors and justifies investment. For casual photographers or travelers seeking compact convenience, the LX10’s all-in-one lens is a practical compromise.

Battery Life and Storage: Endurance on the Go

The S1’s battery life stands at approximately 380 shots per charge (CIPA standard), supported by dual SD card slots enhancing storage security and workflow flexibility - a must in professional contexts. The battery is larger but USB charging support via high-power laptop or power banks integrates well with modern mobility.

The LX10 manages about 260 shots per charge, with a single SD card slot and USB 2.0 port. While respectable for a compact, it’s less resilient for extended shooting days.

Connectivity and Features: Modern Conveniences

Both cameras offer built-in wireless connectivity, but only the S1 includes Bluetooth alongside Wi-Fi, enabling more seamless tethering and remote control via Panasonic’s apps. The LX10 lacks Bluetooth and has limited wireless integration.

On the video front, the S1 shoots 4K UHD at up to 60p with 150 Mbps bitrate and supports advanced codecs (H.264 and H.265), plus linear PCM audio recorded via dedicated microphone and headphone ports - a boon for videographers wanting quality sound monitoring. The LX10 records 4K 30p at 100 Mbps but lacks microphone/headphone jacks, targeting casual video creators rather than professionals.

Durability and Weather Resistance: Built to Withstand

The S1 is rugged, boasting comprehensive weather sealing to resist moisture and dust ingress. This design choice ensures reliability when shooting in rain, dusty trails, or cold environments down to freeze-proof levels. The LX10 carries no such protection, reinforcing its role as an indoor/outdoor but weather-cautious companion.

User Interface and Control: Intuitive Meets Intensive

Examining the rear interfaces shows how Panasonic balances complexity with usability:

The S1 features customizable, illuminated buttons and a powerful menu system, accessible through touch and dials. Its OLED top display reduces reliance on the main screen for essential info. The LX10, streamlined, offers a simple menu and no backlit controls, appealing to those desiring ease without micromanagement.

Photo Genres: Which Camera Suits Which Discipline?

I’m often asked: “Which camera is best for wildlife, landscape, portraits, or street photography?” Let’s break it down.

Portraits

The S1’s full-frame sensor paired with its extensive focus points and face detection delivers beautiful skin tones, creamy bokeh, and precise eye detection - crucial for stunning portraits with shallow depth-of-field effects. The Leica L-mount lens ecosystem offers plenty of fast prime options to enhance portrait work.

The LX10’s fast 24-72mm lens (f/1.4-2.8) is surprisingly competent for casual portraits and indoor events, especially thanks to its close focusing and sensor-shift stabilization, though depth-of-field effects are more limited by the small sensor.

Landscapes

With 14.5 stops of dynamic range and 24MP resolution, the S1 is tailor-made for landscapes requiring maximum detail retention in skies and shadows. Its robust weather sealing encourages all-weather shooting.

The LX10 captures attractive landscapes but lacks the resolution and dynamic range to satisfy highly demanding print or commercial work.

Wildlife & Sports

9 fps continuous shooting with AF tracking, a large and fast buffer, and rugged build define the S1’s suitability here. The LX10’s simpler AF and limited zoom range restrict its effectiveness in these fields.

Street Photography

The LX10’s stealth, size, and quick start-up make it a fine street shooter. The absence of an EVF is a slight inconvenience, but its quiet shutter and portability compensate.

The S1 is bulkier and draws more attention but offers superior image quality, especially in low light.

Macro & Close-up

Both support focus stacking and post-focus modes, but S1’s lenses provide greater magnification and precision focusing.

Night and Astro

The S1’s full-frame sensor excels at high ISO, long exposures, and noise control - critical for astrophotography. The LX10 can dabble but noise at high ISO limits results.

Video Creators

The S1’s advanced codecs, high bitrate, 4K60p, and true audio control are designed for serious video producers. The LX10 is suitable for casual 4K video but lacks professional audio interfaces.

Travel Photography

The LX10’s pocketable design and versatile zoom win here. The S1 is travel-worthy if you prioritize image quality over portability.

Professional Use

Dual card slots, robust build, and top-end imaging put the S1 squarely in the professional camp.
