Comparing the Panasonic Lumix G100 and Lumix TS25: Which Panasonic Fits Your Photography Goals?

In the sprawling world of digital cameras, Panasonic occupies an intriguing niche - especially with systems that blend mirrorless innovation and rugged durability. Today, I’m diving deep into two distinctly different offerings from Panasonic: the Lumix DC-G100 (popularly called the G100) and the much older but still relevant Lumix DMC-TS25 (also known as the Lumix FT25). They could hardly be more different in target audience, design philosophy, and technological approach.

Over the course of considerable hands-on testing, I’ve dissected their specs, performance, and real-world usability to give you an authoritative, expert-level comparison across genres and use cases. Whether you’re a budding vlogger, an adventurous hiker, or just someone wanting a robust travel companion, this breakdown should help align your needs with the strengths of these cameras.

Physicality and Ergonomics: Compact Versus Comfortable

Before we plunge into sensors and autofocus, consider the physical design differences that’ll influence your day-to-day shooting experience:

At first glance, the Lumix G100 follows Panasonic’s familiar SLR-style mirrorless body design, sporting an ergonomically sculpted grip with enough heft to feel stable yet remaining reasonably portable (116x83x54mm, 352g). The TS25, by contrast, is ultra-compact and pocketable - more akin to a chunky point-and-shoot but with ruggedized intentions (104x58x20mm, 144g). Its flat, squat form factor fits comfortably in hand but lacks the tactile control surfaces you get on the G100.

If you prize control buttons and dials over minimalism, the G100 wins hands-down here. Its layout accommodates one-hand shooting, thumb-operated menus, and a thoughtful button arrangement - vital when focusing on precise framing or making quick exposure adjustments out in the field.

Above, you can see how the G100 includes dedicated dials for shutter speed and exposure compensation - features you won’t find on the TS25. The TS25’s fixed lens design comes with just a few physical buttons that largely handle playback and menu navigation, reflecting its casual snapshot focus.

Ergonomics takeaway:
If you value a purposeful grip and tactile command, the G100’s design practically demands to be used as a serious creative tool. For ultra-light travel or rugged adventures where size and waterproofing dominate, the TS25’s compact, simple build fits better.

Sensor Technology and Image Quality: The Heart of Performance

Now, let’s dive under the hood - sensor size, resolution, and image rendering that directly affect your pictures.

The Lumix G100 employs a 20-megapixel Four Thirds CMOS sensor measuring 17.3 x 13 mm, a sensor area roughly 8 times larger than the TS25’s 1/2.3" CCD sensor (6.08 x 4.56 mm; 16MP). This difference has widespread implications for image quality:

• Dynamic range: G100’s larger sensor coupled with modern CMOS tech captures significantly better highlight and shadow detail. That means richer, more nuanced landscapes and portraiture with fewer blown highlights or crushed shadows.
• Low light performance: Thanks to its native ISO range starting at 200 and maxing at 25600, the G100 is far better equipped for shooting in dim conditions, exhibiting cleaner images with less noise - about the only time composite noise reduction processing on the TS25 can’t compensate.
• Resolution: While the TS25’s 16MP sensor still produces decent prints up to 8x10 inches, the G100’s 20MP sensor affords more detail and cropping freedom, crucial for wildlife or sports photography where framing adaptability matters.

The TS25’s CCD sensor does have anticipated drawbacks: lower dynamic range, more noise above ISO 800, and a tendency towards softer images in general due to limitations of its smaller sensor size and older optics.

Image Quality summary:
The G100 delivers a substantially more advanced sensor experience, yielding professional-grade image files suitable for expressive editing workflows and large prints. The TS25 fits casual users who prioritize convenience and ruggedness over maximum image fidelity.

Viewfinding, LCD Screens, and User Interface: Framing Made Effective

Successful shooting depends heavily on how you compose and review images. The two Panasonic models differ markedly in this realm.

The G100 sports a 3-inch fully articulating touchscreen with a sharp 1.84 million-dot resolution - perfect for vlogging and shooting from challenging angles. Touch focus and tap-to-shoot features afford quick adjustments. The electronic viewfinder (EVF) is crisp, sporting 3,680 dots and 100% coverage, facilitating precise manual focusing and stable composition in bright outdoor light.

On the flip side, the TS25 has a 2.7-inch fixed TFT LCD screen with just 230k dots, significantly limiting preview clarity and interface responsiveness. It offers no electronic viewfinder, so outdoor framing requires careful angling to avoid glare. The lack of touchscreen means navigating menus can be slow and clunky.

From a usability standpoint, the G100’s UI is modern and intuitive, easing the transition for users who expect smartphone-style controls. While it isn’t the fastest mirrorless interface on the market, the touchscreen responsiveness and logical menu layering make it well suited for beginners and pros alike.

Framing and interface verdict:
If you care about flexible framing, clear preview, and touchscreen control, the G100 clearly surpasses the TS25’s entry-level display system.

Focusing and Speed: Is Autofocus a Dealbreaker?

Autofocus performance can make or break a camera, especially with active subjects.

• The G100 uses contrast-detection autofocus with 49 focus points, including face detection and tracking capabilities. While not as lightning-fast as phase-detection AF on flagship models, Panasonic’s algorithms perform reliably when tracking people in portraits, keeping clarities tight with continuous AF modes. The G100 also features manual focus with focus peaking, and in-body features like focus stacking and bracketing - great tools for macro and landscape photographers.

• The TS25 features a more basic contrast-detection AF with just 23 points and no face or eye detection. Autofocus is significantly slower and less precise. There’s no manual focus capability. At 1 fps burst speed, action shooters will be frustrated.

Given that wildlife and sports photography demand fast and accurate focus acquisition, the G100 holds a distinct advantage, whereas the TS25 is best for static or slow-moving subjects and casual shooting.

Lens Ecosystem and Compatibility: Building a System or Shooting with One Lens?

An important consideration: the breadth and quality of lenses you can pair with these cameras.

• The G100 uses the Micro Four Thirds (MFT) mount, Panasonic’s widely supported, versatile system shared with Olympus. There are well over 100 native lenses ranging from ultra-wide primes, super telephotos, fast portraits lenses, to specialty macros. This ecosystem also includes third-party options offering affordable alternatives. The focal length multiplier of 2.1x augments telephoto reach, making wildlife or sports shooting more accessible.

• The TS25, in contrast, has a fixed 25-100mm equivalent zoom lens with a modest aperture of f/3.9 - f/5.7. There’s no scope for lens change or upgrades, locking you into whatever compromises the built-in lens imposes.

This fundamental difference defines a critical user choice: do you want a flexible system camera that can grow with you - or a ready-to-shoot rugged point-and-shoot?

Build Quality, Durability, and Weather Resistance: Can Your Camera Brave the Elements?

Here, the TS25 truly differentiates itself.

• It features waterproofing up to 7 meters, alongside dustproof, shockproof, and freezeproof capabilities. This makes it an excellent companion for adventurous users who shoot near water or in rugged conditions without risking damage. Its compact body, combined with toughened specs, means worry-free operation on hikes, beach days, or casual underwater photography.

• By comparison, the G100 has no weather sealing or ruggedized protections. It’s a delicate mirrorless camera that requires care during outdoor shoots - rain or dust can be problematic without extra protective gear.

Build-quality-wise, the G100 is a well-made mirrorless body with a plastic chassis and a durable feel, but it caters to photographers prioritizing image quality and system expansion over ruggedness.

Portrait Photography: Skin Tones, Bokeh, and Eye Detection

Portraiture benefits tremendously from sensor size, autofocus accuracy, and lens quality.

• The G100’s sensor paired with MFT fast portrait lenses yields creamy bokeh and excellent skin tone rendition thanks to accurate color science. Its face and eye detection improve subject tracking - even challenging for entry-level cameras. Portrait backgrounds separate smoothly.

• The TS25’s smaller sensor and mid-range zoom lens produce flatter images, with limited background blur and less nuanced color. No eye detection limits precise focus on eyes, leading to miss-focused portraits.

For portraits, the G100 is your clear winner, especially if you value sharp eyes and softly defocused backgrounds.

Landscape Photography: Dynamic Range and Resolution Tested

Landscape photographers live or die by sensor performance, resolution, and weather durability.

• The G100’s higher dynamic range preserves sky detail and shadow textures, giving you latitude for post-processing. Its 20MP files print well and crop for composition. While lacking weather sealing, the camera’s small form still allows packing with careful lens choices for rugged shooting.

• The TS25’s built-in lens limits wide-angle reach (25mm equivalent) and resolution coupled with low sensor efficiency delivers lower image quality from challenging lighting scenes. However, its waterproof rating makes it a viable option for underwater landscapes or aquatic nature shots where other cameras cannot go.

Wildlife and Sports: Speed, Autofocus, and Burst Rate Comparison

Wildlife and sports photography demand fast shooting capabilities, accurate autofocus, and high burst frame rates.

• The G100 offers 10fps continuous shooting with autofocus tracking - a strong performance for an entry mirrorless camera. Its native lens selection (including telephotos up to 300mm+) paired with AF tracking improves capture rates of fast animals or athletes.

• The TS25 caps at 1fps burst, which is impractical for dynamic subjects. Its autofocus is also slower and less reliable in this context.

Street Photography and Travel: Portability, Discretion, and Battery Life

Street and travel photographers seek cameras that are light, unobtrusive, and versatile.

• The TS25’s sleek, compact, waterproof form makes for inconspicuous shooting in urban and outdoor environments alike. At only 144g, it can go anywhere, including wet environments you’ll hesitate to bring the G100.

• The G100, while larger and heavier, remains quite portable for an interchangeable lens camera. Its articulating screen and excellent video features appeal to travel vloggers and storytellers, despite the slightly lower battery life (270 shots per charge vs. 250 on TS25).

Macro and Night Photography Capabilities

Macro shooters benefit from precision focus and stabilization:

• The G100 supports focus bracketing, stacking, and post-focus features, which dramatically improve macro shooting success. Though it lacks in-body stabilization, many MFT lenses include optical IS.

• The TS25 has a minimum macro focus distance of 5cm but lacks focus stacking and bracketing, offering limited creativity in close-up shots.

For night and astro photography, the G100’s superior high-ISO performance makes long exposures more feasible. The TS25’s maximum ISO 6400 is nominal but noisy, limiting astrophotography potential.

Video Features: Vlogging, 4K, and Audio Options

Video shooters get very different tools:

• The G100 targets content creators explicitly. It can record 4K (up to 30p) and Full HD at 120fps for slow motion, with clean HDMI output, built-in mic jack (though no headphone jack), and an articulating screen to frame yourself for vlogging. Panasonic’s video codec choices support flexible editing.

• The TS25 offers only 720p video at 30fps - suitable for casual clips but nowhere near professional or enthusiast video standards.

Connectivity, Storage, and Battery: Everyday Practicalities Matter

• The G100 offers built-in Wi-Fi and Bluetooth for quick image transfer and remote control via smartphone apps, plus a versatile single SD card slot supporting UHS-I.

• The TS25 lacks wireless connectivity but also supports SD cards with some internal memory, useful for backup.

Battery life on both hovers around 250-270 shots, typical for small cameras, but the G100’s real-world shooting with video active might drain faster - carrying a spare battery is advised.
