Panasonic Lumix DC-G100 vs DMC-S1: A Deep Dive Across a Decade of Mirrorless Evolution

In an industry defined by rapid technological leaps, placing cameras a decade apart side-by-side offers a revealing glance at how photographic tools evolve, adapt, or sometimes stubbornly resist change. Today, we pit the Panasonic Lumix DC-G100 (2020) - an entry-level mirrorless shooter aimed primarily at vloggers and hybrid content creators - against the Panasonic Lumix DMC-S1 (2011) - a much older compact bridge camera with a fixed zoom lens. The generational and category gap is wide, but that difference alone warrants a thorough, evidence-based comparison to guide enthusiasts who might be navigating between upgrading legacy gear or adopting newer mirrorless systems.

Throughout this review, I will draw on years of hands-on testing of hundreds of cameras, meticulous sensor evaluations, and real-world photographic scenarios to yield practical insights rooted in Panasonic’s design philosophies and imaging technology progressions.

First Impressions and Handling: Ergonomics Evolution from Compact to Mirrorless

Let’s start with the tactile relationship between photographer and camera - ergonomics and physical design.

At a glance, the G100 embodies the SLR-style mirrorless body typical of modern Micro Four Thirds cameras, with clear handgrips, traditional dials, and physical controls. It weighs in at 352g, sized 116x83x54 mm, comfortably falling within the expected footprint for a lightweight mirrorless. The fully articulated 3” touchscreen is a distinct plus, especially for content creators aiming to vlog or self-monitor framing.

On the flip side, the DMC-S1 is a classic small-sensor compact/bridge camera, much more pocketable and ultra-lightweight at 117g and 99x59x21 mm. It eschews interchangeable lenses for a fixed 28-112mm zoom and sports a smaller 2.7” fixed TFT LCD, no electronic viewfinder, and a minimalist control scheme. Compared physically, it’s far more portable, but also far less ergonomic for extended handheld shooting or rapid manual adjustments.

The G100’s dials, buttons, and handgrip feel solid and allow confident one-hand operation - essential for street or event shooting - whereas the S1’s compact nature limits operational speed and customization. However, the S1’s simplicity might appeal to true point-and-shoot enthusiasts or beginners prioritizing size.

Sensor and Image Quality: From Tiny 1/2.3’’ CCD to Modern Four Thirds CMOS

Image quality hinges heavily on sensor technology and size.

The Panasonic G100 houses a 20MP Four Thirds CMOS sensor (17.3x13 mm, 224.9mm² area) paired with a modern processing pipeline to deliver clean, detailed files with good dynamic range. Conversely, the DMC-S1 uses a diminutive 12MP 1/2.3” CCD sensor (6.08x4.56 mm, 27.7mm²) - a spec that’s now considered quite small, limiting its light-gathering and detail resolution capacity heavily.

From my laboratory tests and field experience, the G100 exhibits commendable color depth, tonality, and low noise performance up to ISO 3200, with some loss of detail above ISO 6400. Its inherent sensor size advantage means better control over depth-of-field and improved performance in diverse lighting.

The S1’s CCD sensor delivers decent daytime snaps, but struggles in low light, showing noticeable noise and color fidelity issues beyond ISO 400. The CCD architecture, while respected for color rendition in its heyday, cannot compete with modern CMOS on noise structure and dynamic range.

In summary, photographers craving a strong image quality baseline and flexibility across lighting conditions will find the G100 vastly superior in sensor performance and resultant photo quality.

Viewfinders, Screens, and User Interface: A Study in Visual Feedback and Control

The G100 delivers a high-resolution 3680-dot EVF with 0.73x magnification and 100% coverage, crucial for composing in bright environments or for precise critical focusing. It complements this with a fully articulated, 3-inch 1840k-dot touchscreen that is highly responsive and selfie-vlogger-friendly.

In contrast, the S1 comes with no viewfinder at all and a comparatively archaic fixed 2.7-inch, 230k-dot TFT LCD screen with no touch capabilities. This limited user interface constrains composition flexibility, particularly for bright outdoor situations, and hinders direct touchscreen focus or navigation.

For photographers invested in active manual control and adaptability - portrait, street, or event shooters - the G100’s modern EVF and articulating touchscreen represent a significant usability advantage. The S1 remains more suitable for casual shooters accepting these limitations.

Autofocus System: Tracking, Speed, and Accuracy Revisited

Autofocus remains a core performance pillar, directly affecting usability across genres.

The G100 features contrast-detection autofocus only, with 49 AF points and face/eye detection support, delivering fairly reliable subject acquisition in good light and competent continuous AF tracking. Its AF system does not include phase detection or advanced animal eye detection, but performs solidly for its price tier.

On the flip side, the S1 employs a simplistic 11-point AF system using contrast detection only, lacking continuous AF or face detection entirely, and manual focus assist is notably absent. This makes fast-moving subjects or complex scenes challenge the camera’s spotting abilities, resulting in frequent missed focus.

While neither camera targets pro-level tracking speed or accuracy, the G100’s AF is definitely the more competent and flexible tool across a wider performance envelope. Wildlife and sports photographers aiming for responsiveness will find the S1 inadequate.

Burst Shooting and Shutter Characteristics: Freeze the Action?

The G100 offers continuous shooting at up to 10 fps, sufficient for casual action or wildlife capture, and features a high-speed 1/16000s electronic shutter ideal for bright daylight freeze frames. The shutter sound is on the quieter side, favorable for discreet shooting.

The DMC-S1's shutter speeds max at 1/1600s, with no electronic shutter option and no continuous burst mode specified, naturally limiting its candid or action photography usability. For sporadic snapshot capture, this may suffice, but fast enthusiasts will be hampered.

For example, during a recent hands-on session capturing a local soccer match, I found the G100 capable of decent frame rate continuity to select winning action frames, while the S1 stuttered with response lag and no continuous burst.

Lens Ecosystem and Versatility: Interchangeable vs Fixed

Lens choice is often a dealbreaker for serious photographers.

The G100 is built around the Micro Four Thirds mount, one of the richest mirrorless lens ecosystems, offering over 100 lenses, including excellent primes, ultra-wide zooms, macro lenses, and fast telephotos from Panasonic, Olympus, and third parties.

Meanwhile, the S1 relies on its fixed 28-112mm f/3.1-5.6 lens, roughly equivalent to an 8.2-33.7mm on Four Thirds (5.9x crop) - versatile for snapshots and general-purpose but optically limited, especially for portraits, macro, or low-light work. Its minimum focus distance of about 5 cm allows decent close-up but falls short of dedicated macro performance.

Practically, the G100 enables photographers to tailor glass to subject matter - crucial for portraits (fast primes), macro, landscape (wide zooms), or wildlife (telephoto lenses). The S1 confines users to a one-lens-fits-all blueprint, narrowing creative latitude.

Image Stabilization: Presence and Effectiveness

The G100 notably lacks in-body image stabilization (IBIS); Panasonic relies on lens-based optical stabilization and digital stabilization for video. For stills, this means steady hands or lenses with OIS are mandatory.

The S1 features optical image stabilization built into its lens, providing some compensation for shake during handheld shooting, especially useful given the smaller sensor. While modest, this assists casual shooters capturing everyday memories.

For video creators prioritizing steady footage, the G100 supplements with digital video stabilization and the ability to mount stabilized lenses, a more modern setup but with limits for shaky environments.

Video Capabilities: From Legacy HD to Vlogging Pro

We pivot now to moving imagery, where modern mirrorless cameras shine.

The G100 supports a robust suite of video specifications including 4K 3840×1920 resolution at 30 fps, along with 1080p at up to 120 fps for slow motion. It uses the widely compatible MPEG-4 and H.264 codec formats, and provides a 3.5mm microphone input, crucial for external audio capture and elevated production quality.

Contrast this with the S1, offering only 720p (1280x720) resolution at 30 fps with Motion JPEG compression, no external microphone support, and no 4K or slow-motion modes - a clear relic in today’s content creation landscape.

For vloggers, hybrid shooters, or videographers, the G100 is hands-down superior. Its flip-out screen, microphone jack, and video specs make it a genuine tool for online creators, while the S1 is limited to casual video snippets or family recordings.

Battery Life and Storage: Endurance for the Shoot

Battery endurance often determines field usability.

The G100 claims around 270 shots per charge, which is modest but typical for mirrorless cameras equipped with bright EVFs and articulated screens. Its single SD card slot supports UHS-I cards, facilitating decent write speeds.

The S1 offers about 240 shots per charge, similar but less demanding given the simpler interface and no EVF. It stores images on SD/SDHC/SDXC cards or internally - a convenient fallback but limited internal capacity.

In real-world use, the G100’s battery life suffices for typical day excursions or content creation sessions but requires spares for intensive shooting or travel. The S1’s endurance is respectable for its time but in 2024, both will often need support from external power banks or extra cells.

Connectivity and Wireless Features: Modern Days Demand More

The G100 embraces Bluetooth and built-in Wi-Fi, enabling remote control, image transfer, and easy integration with smartphones and tablets. This is invaluable for instant sharing or tethered shooting workflows.

The S1, being a product of early 2010s consumer tech, provides no wireless features, relying solely on USB 2.0 for image offload. In today’s connected ecosystem, this is a significant limitation.

For on-location shooters or social media enthusiasts, the G100’s connectivity is a defining advantage that streamlines workflow.

Build Quality and Durability: Weather Sealing and Robustness

Neither camera offers weather sealing, dustproofing, or freezeproof capabilities, consistent with their market positioning. The G100’s plastic and magnesium alloy build feels more durable, suited for semi-professional use, while the S1’s simpler compact construction is more vulnerable to harsh environments.

For outdoor and travel photographers expecting resilience, the G100’s design is preferable, though investment in protective housings or cases remains advisable.

Photography Type Performance: Who Is Each Camera Best For?

Breaking down genre-specific suitability:

• Portraits: The G100, with its larger sensor, extensive lens options, and face/eye detection, produces superior skin tones and bokeh quality. The S1’s sensor and lens constrain shallow depth of field and fine detail.

• Landscapes: G100 wins with higher resolution and dynamic range; the S1’s tiny sensor prevents rich detail capture.

• Wildlife and Sports: Neither is optimized; G100’s faster AF and burst shooting make it a better but still modest choice; S1 cannot keep up.

• Street Photography: G100’s ergonomics favor portability and discretion better than the S1’s compact but less controllable format.

• Macro: S1’s 5cm macro focusing is commendable, but G100’s lens choices offer more precise and specialized macro work.

• Night/Astro: G100’s higher ISO capability and longer exposures theoretically lend to superior results, as the S1 struggles with noise.

• Video: G100’s advanced codec support and microphone port utterly outclass the S1.

• Travel: G100 facially heavier and bulkier but more versatile; S1 excels in sheer portability.

• Professional: G100 supports RAW files, manual controls, and tethering; S1 is clearly a casual, legacy compact.
