Panasonic Lumix DMC-GF1 vs. DMC-TS20: An In-Depth Comparison for Photographers

Selecting an appropriate camera demands a nuanced understanding of one’s photographic discipline, environment, and technical preferences. We undertake a meticulous comparative analysis of two distinct Panasonic models - the Lumix DMC-GF1, a 2009 entry-level mirrorless camera, and the Lumix DMC-TS20 (aka FT20), a 2012 rugged waterproof compact. Both cater to different niches and user intents, yet this evaluation provides an expert foundation for discerning photographers aiming to match gear capabilities to their practical needs.

Physical Design and Handling: Ergonomics Meets Portability

The Lumix GF1 adopts a rangefinder-style mirrorless body, emphasizing manual controls and a substantial grip ergonomics. In contrast, the TS20 emphasizes compactness and rugged resilience, designed for challenging conditions but restricting handling complexity.

• GF1 Dimensions: 119 x 71 x 36 mm; Weight: 385 g
• TS20 Dimensions: 101 x 58 x 19 mm; Weight: 142 g

The GF1’s larger footprint allows for a fuller hand grip, more prominent control dials, and manual input wheels, which facilitate rapid exposure adjustments on the fly - a critical advantage in professional settings. Conversely, the TS20’s ultra-compact size and minimized protrusions cater well to casual or adventure photographers requiring pocketable, robust equipment.

Both cameras omit electronic viewfinders (EVFs), but the GF1 has a fixed 3-inch LCD with a resolution of 460k dots, compared to the TS20's 2.7-inch 230k dots screen. The difference in display quality and size significantly impacts usability, as detailed later.

In the top-view comparison, the GF1 shows dedicated dials for shutter speed, exposure compensation, and manual aperture control - a luxury absent from the TS20, which relies on automatic modes and fewer physical controls, reflecting its more consumer-centric design.

Sensor Technology and Image Quality: Micro Four Thirds Versus Compact CCD

A camera’s sensor size and technology form the backbone of image quality, dynamic range, and noise performance.

• GF1 Sensor: Four Thirds CMOS, 12 MP, 17.3 x 13 mm (sensor area 224.9 mm²)
• TS20 Sensor: 1/2.3" CCD, 16 MP, 6.08 x 4.56 mm (sensor area 27.7 mm²)

The GF1’s Micro Four Thirds sensor offers a substantial advantage in sensor area - over 8 times the surface area of the TS20’s sensor - translating into superior light-gathering capability, dynamic range, and lower noise characteristics especially in low light. The 12 MP resolution of the GF1 is balanced to optimize pixel size and image fidelity, while the TS20’s 16 MP count stems from a smaller CCD with smaller photosites, which can increase noise levels and reduce high-ISO performance.

According to DxO’s testing, the GF1 scores:

• Overall: 54 points
• Color Depth: 21.2 bits
• Dynamic Range: 10.3 EV
• Low Light ISO: 513

The TS20 lacks formal DxO Mark testing, but based on sensor specs and experience with similar compact cameras, it likely delivers inferior dynamic range and high-ISO noise handling.

Practical implication: Photographers prioritizing image quality, extensive post-processing latitude, and acceptable noise at elevated ISOs benefit materially from the GF1’s sensor performance.

Autofocus System: Precision Versus Simplicity

The GF1 employs a hybrid autofocus system with 23 focus points relying on contrast-detection autofocus (CDAF), with face detection enabled but not animal eye AF. It supports single AF, continuous AF, and tracking, giving it flexibility in various shooting scenarios.

The TS20 also utilizes contrast-detection AF with 23 points but does not support face detection. AF modes are limited to single and continuous, lacking more sophisticated subject tracking.

When tested, the GF1’s AF system delivered respectable accuracy and speed for its era, facilitating precise manual focus override - important for creative control in portraiture or macro work.

The TS20’s AF prioritizes simplicity and robustness over speed or accuracy, with focus hunting more noticeable, particularly in dim environments and at longer focal lengths.

Summary: Serious photography that requires fast, reliable focusing favors the GF1, especially for moving subjects or selective focusing needs.

Exposure Controls and Manual Operation

The GF1 includes the full manual exposure suite - shutter priority, aperture priority, manual exposure modes, exposure compensation, and custom white balance - with shutter speeds between 60 seconds and 1/4000 sec.

The TS20 offers only automatic exposure with limited white balance options and no exposure compensation or priority modes; shutter speeds range from 8 to 1/1300 sec.

The GF1’s manual controls extend to raw image shooting, a feature absent in the TS20, limited to JPEG compression.

For photographers engaging in controlled studio portraiture, landscapes requiring precise settings, or low-light astro photography demanding bulb mode, the GF1 provides undeniable flexibility.

LCD Screen and Viewfinder Experience

Despite both lacking an EVF, the GF1’s 3-inch 460k-dot TFT LCD with wide viewing angles enables comfortable live view framing and menu navigation.

The TS20’s 2.7-inch 230k-dot TFT LCD is considerably less sharp, affecting critical focusing via live view.

This difference impacts macro photography and manual focusing tasks, where precise screen preview is essential.

Lens Ecosystem and Compatibility

One of the Panasonic GF1’s strongest points involves its Micro Four Thirds mount compatibility, supporting a diverse range of lenses including Panasonic, Olympus, and third-party manufacturers.

The available lens array exceeds 100 lenses with focal ranges from ultra-wide to super-telephoto, allowing users to tailor their setups for every discipline - portraiture, wildlife telephotos, macro optics, or landscape tilt-shift lenses.

Conversely, the TS20 features a fixed 25-100 mm equivalent zoom lens (f/3.9-5.7 aperture range), prioritizing simplicity over versatility.

While this lens is splash-proof and sufficient for casual travel or underwater scenes, it limits optical quality and depth-of-field control compared to interchangeable lenses.

Burst Shooting and Video Capabilities

Burst rates are modestly improved on the GF1 with 3 fps continuous shooting, adequate for moderate action and sports photography, whereas the TS20 offers 1 fps, reflective of its compact sensor and processing limits.

Video recording on the GF1 supports HD 720p at 30 fps in AVCHD Lite format, with no external microphone input - adequate for entry-level HD video but limited by modern standards.

The TS20 records 720p video at 30 fps in MPEG-4 format, offering typical point-and-shoot video quality.

Both cameras do not support 4K video or advanced video features; however, the GF1's manual exposure during video affords better creative control in low-light or fast-moving subject scenarios.

Durability, Environmental Sealing, and Specialized Use

The TS20 stands out for solid environmental sealing - waterproof (up to 7 m), shockproof (drop resistance up to 1.5 m), dustproof, and freezeproof down to -10°C - which the GF1 conspicuously lacks.

This makes the TS20 a robust choice for underwater photography, hiking, and adventure travel where mechanical vulnerabilities and weather conditions preclude use of fragile mirrorless systems.

The GF1, without any weather sealing, is better suited to controlled or urban environments, where protection from elements is less critical.

Battery Life and Storage Options

• GF1 Battery life: Approximately 380 shots per charge
• TS20 Battery life: Approximately 250 shots per charge

The GF1 allows storage on SD, SDHC, and MMC cards, while the TS20 supports SD, SDHC, SDXC, and has internal memory as backup.

Given the GF1’s higher power draw linked to its larger sensor and processor, its battery life remains practical for day shooting, but not extensive field use without spares.
