Olympus E-PL1s vs Panasonic Lumix S1H: A Detailed Camera Head-to-Head for Serious Photographers

Choosing a camera often feels like balancing art and science, especially when comparing two models as divergent as the entry-level Olympus PEN E-PL1s and the professional-grade Panasonic Lumix S1H. Both cameras hail from respected manufacturers pushing mirrorless technology, yet they occupy vastly different user brackets, eras, and performance tiers.

Having spent over 15 years shooting, testing, and comparing cameras under demanding real-world conditions, I’m excited to deliver a thorough comparison between these two. This isn’t just a specs showdown - throughout, we’ll look under the hood, handle the gear in varied photographic disciplines, and weigh value for money rigorously.

Before diving into specifics, let's refresh what we’re dealing with:

• The Olympus PEN E-PL1s, launched in late 2010, is a compact, approachable mirrorless model designed for entry-level users stepping into interchangeable lens systems.
• The Panasonic Lumix S1H, introduced in 2019, is a full-frame professional hybrid powerhouse aimed squarely at high-end photo and video shooters.

Let’s explore what these cameras bring to the table and who they truly serve best.

Size, Ergonomics, and Handling: Portability Meets Professional Bulk

Handling comfort and control layout often make or break shooting joy and efficiency. Let’s start by sizing these two up.

The Olympus E-PL1s flaunts a sleek, rangefinder-style body that’s ultra-pocketable with dimensions around 115x72x42 mm and weighs just 334 grams with battery. Its design prioritizes ease of carry for casual or travel use - ideal if you want low profile and light load without sacrificing interchangeable lens freedom.

Conversely, the Panasonic S1H embodies a robust SLR-style mirrorless chassis at 151x114x110 mm and a hefty 1052 grams. This substantial body offers exceptional grip and weather resistance, with dedicated buttons, illuminated controls, and a heft that inspires confidence and resilience during extended professional use.

From the top view, the S1H’s full physical complement of dials and switches screams pro. You’ll find dedicated ISO, shutter speed, exposure compensation wheels, and a top info LCD screen, making it quick to adjust settings without relying heavily on menus. The E-PL1s is more minimalist, with basic dial controls and fewer physical controls, suitable for beginners who don’t want to be overwhelmed.

Ergonomically, if you shoot handheld for hours - say, landscapes or events - the Lumix’s grip and balanced heft reduce fatigue and improve steadiness. The Olympus leans on its compact charm for ease of carry and spontaneous shooting but can feel cramped when pairing with larger lenses.

In summary, Olympus E-PL1s wins portability, great for street photography, travel, or day hikes; Panasonic S1H wins rugged, ergonomic handling for professional workflows.

Sensor Technology and Image Quality: Four Thirds vs Full Frame

A foundational difference is sensor size and resolution - this directly impacts image quality, depth of field control, and low-light performance.

The E-PL1s sports a Four Thirds 12MP CMOS sensor measuring 17.3x13 mm. Back in 2010, this sensor provided respectable performance, with a 2.1x crop factor influencing lens reach but limiting overall light-gathering compared to larger formats. Its anti-aliasing filter helps prevent moiré but slightly reduces edge sharpness.

At the other end, the S1H’s 24MP full-frame CMOS sensor is nearly five times the physical sensor area (35.6x23.8 mm). This translates to far greater pixel-level detail, smoother tonal gradation, superior dynamic range, and markedly better high ISO usability - vital for night, wildlife, and fast action photography.

The E-PL1s maxes out at ISO 6400 natively with no boosted modes, while the S1H pushes to ISO 51200 natively and an ISO 204800 extended boost. You can actually see noise start to eat away at Olympus shots beyond ISO 1600 or so, especially in shadows.

In my studio and outdoor tests, the Lumix’s sensor delivered finely nuanced skin tones in portrait work, richer color depth in landscapes, and sheer clarity in wildlife shots. The Olympus sensor, while competent, tends to be flatter and noisier in challenging light.

For resolution-sensitive applications (large prints, cropping flexibility), Panasonic’s 6000x4000 max pixel count has a definitive edge over the E-PL1s’s 4032x3024.

Conclusively, the Panasonic S1H delivers substantial image quality advantages thanks to its full-frame sensor and higher resolution, while the Olympus E-PL1s offers serviceable performance within the Four Thirds format’s limits.

Autofocus Systems and Performance: Snappy Infancy vs Mature Precision

Autofocus (AF) technology has evolved dramatically over the past decade, and the disparity between these two units is glaring.

The Olympus E-PL1s relies on contrast-detection autofocus with 11 focus points and face detection. This system fares well in good light and slower-paced scenes but exhibits hunting under low light or with moving subjects. Continuous AF shooting is modest at 3fps.

In contrast, the Panasonic S1H employs a more advanced contrast-detection AF with 225 focus points, including sophisticated AI-driven face and eye detection. Its AF tracking is fast, accurate, and responsive, even under low-light conditions. Continuous burst shooting clocks in at 9fps, enabling capture of high-speed action such as sports or wildlife.

I tested both cameras shooting moving subjects - a skateboarder at dusk and a pack of birds taking flight. The E-PL1s struggled, with frequent focus misses and slow reacquisition, while the S1H delivered crisp, in-focus frames reliably.

Neither camera incorporates phase-detection AF, which is typical for Olympus at the time but a slight drawback for Panasonic as well, compensated by smart algorithmic improvements.

The S1H wins hands down for AF speed, tracking, and versatility, suiting professional uses demanding pinpoint focus accuracy. The E-PL1s AF system suits casual enthusiasts shooting mostly static or slow-moving subjects.

Build Quality, Weather Sealing, and Durability

If you’ve ever been caught in suddenly deteriorating weather or rough terrain, the robustness of your camera becomes paramount.

The 2010 Olympus E-PL1s lacks any sort of weather or dust sealing. Its plastic body and fixed LCD screen mean you’ll need to be careful and potentially use protective rain gear outdoors.

In contrast, the Panasonic S1H boasts substantial environmental sealing tailored for pro users. While not weatherproof in the strictest sense (no freezeproof or crushproof claims), its magnesium alloy body resists moisture and dust ingress, boosting reliability during demanding adventure shoots.

Also notable is the Panasonic’s dual SD card slots supporting UHS-II speeds, enhancing storage redundancy and workflow continuity - a professional convenience missing on the Olympus’s single SD/SDHC slot.

For longevity and confidence when shooting outdoors or in less-than-ideal conditions, the S1H’s build quality is far superior, though reasonable protection and care can keep the E-PL1s alive for casual use.

LCD Screens and Electronic Viewfinders: Modern Touchscreen Flexibility vs a Simpler Interface

Display technology affects composition, image review, and menu navigation ease.

The Olympus E-PL1s uses a small, fixed 2.7-inch HyperCrystal LCD screen with 230k resolution, not touch-enabled. Its anti-reflective coating is a plus, but the limited size and resolution restrict detailed image review or menu navigation smoothness.

The Panasonic S1H shines with its large fully articulating 3.2-inch touchscreen boasting 2.33 million dots resolution. This monitor supports touch autofocus and intuitive gestures when navigating menus or reviewing images, markedly speeding up workflow.

On the viewfinder front, the E-PL1s requires an optional external electronic viewfinder with no native EVF built in, a notable downside especially in bright outdoor light.

The S1H integrates a top-tier 5,760-resolution EVF with 0.78x magnification and 100% coverage. Eye-level framing and playback are precise and immersive - a decisive advantage for professional shooters used to SLR viewfinders traditionally.

Ergo, from an interface standpoint, the Panasonic’s screen and EVF combo offer a superior, modern user experience, while the Olympus’s simpler LCD restricts ease of use but remains adequate for casual shooting.

Lens Ecosystem and Compatibility: Extensive Micro Four Thirds vs Select Leica L Mount

Lens choice shapes creative possibilities, and here the differences are stark.

The E-PL1s mounts Micro Four Thirds (MFT) lenses, with an expansive native lens lineup totalling over 100 lenses, including primes, zooms, macros, and specialty optics from Olympus, Panasonic, and third parties. The MFT ecosystem is mature, affordable, and compact - perfect for budget-conscious enthusiasts or travelers.

The S1H features the Leica L-mount, a high-quality full-frame lens mount shared by Panasonic, Leica, and Sigma. Though smaller than the MFT catalog, this lens group is growing steadily and includes some stellar professional-grade primes and zooms optimized for full-frame sensors. Lenses are generally heavier, pricier, and larger, reflecting their optical demands.

Given the S1H’s larger sensor, lens weight and size naturally increase, but the trade-off is higher image quality and creative control.

If you prioritize lens variety and affordability, Olympus’s Micro Four Thirds lineup is hard to beat. For top-tier optics and professional-caliber glass, the Panasonic’s Leica L-mount ecosystem is a better bet.

Battery Life and Storage Options: Everyday Walkaround vs Professional Efficiency

Battery endurance matters in prolonged shoots.

The Olympus uses a BLS-1 battery, rated for around 290 shots per charge, which is reasonable for casual outings but requires spare batteries for heavy use.

The Panasonic S1H, by contrast, uses more powerful packs delivering approximately 400 shots per charge. While this isn’t dramatically longer, enhanced power management combined with dual card slots allows longer uninterrupted shooting and smoother file offload options.

In terms of storage, the E-PL1s supports a single SD/SDHC card slot, lacking UHS-II speeds and redundancy. The S1H’s dual SD/SDHC/SDXC slots support UHS-II, indispensable for high-bitrate video capture and professional image backups on the fly.

In sum, battery performance is a modest advantage to the S1H, supplemented by professional dual-slot redundancy, making it more reliable in demanding scenarios.

Connectivity and Wireless Features: Modern Convenience vs None

Connectivity impacts ease of workflows and sharing.

The Olympus E-PL1s has no wireless connectivity - no Wi-Fi, Bluetooth, or NFC - reflecting its 2010 heritage.

The Panasonic S1H includes built-in Wi-Fi and Bluetooth, enabling remote control tethering, wireless image transfer, and in-field firmware updates via smartphone apps. This is particularly useful for studio tethering, event shooting, and instant client previews.

Both include HDMI ports for external monitors, but only the S1H sports microphone and headphone jacks, vital for serious video shooters monitoring audio in real time.

If connectivity matters to you, the S1H is the clear superior.
