Drawing upon over 15 years of professional hands-on testing across sensor technologies, autofocus systems, ergonomics, and image quality, I have subjected these two models to meticulous comparative analysis. This article will empower you - with detailed technical insights and real-world performance evaluations - to understand which camera fits your photographic aspirations and budget.

First Impressions: The Ergonomics and Design Divide

Before delving into specifications, the very feel, weight, and control layout of a camera profoundly impact shooting comfort and operational speed - factors vital in landscape hikes or fast-paced wildlife scenarios alike.

Physically, these cameras differ radically: the TG-860 is an ultracompact, compact and lightweight at just 224 grams with dimensions of 110 x 64 x 28 mm, making it pocket-friendly and tough to beat for travel and active lifestyle use. The FZ100, by contrast, weighs more than twice as much at 540 grams, with bulkier bridge-style ergonomics (124 x 82 x 92 mm) that lend more substantial grip and DSLR-style handling.

Such form factors translate directly to use case suitability. The TG-860’s rugged casing is waterproof, shockproof, freezeproof, and crushproof, reassuring for underwater or extreme outdoor activities where worry about environmental damage is minimal. The FZ100 lacks such weather sealing but offers a traditional grip and more physical controls, supporting extended handheld sessions and manual adjustments.

From the top view, the FZ100 presents a more comprehensive control suite, including dedicated dials for shutter/aperture priority and exposure compensation - providing technicians and creative shooters with faster access to essential parameters. In contrast, the TG-860’s simplified button layout aligns with its casual, point-and-shoot philosophy, favoring ease over granular control.

Practical takeaway: For photographers prioritizing portability and resilience during adventure travel or harsh environments, the TG-860’s compact and sealed design dominates. For those needing manual control and ergonomic handling during long sessions or studio-like conditions, the FZ100’s heft and layout better serve.

Sensor and Image Quality Insights: The Heart of the Matter

Both cameras sport small 1/2.3" CMOS sensors - standard for their respective classes - but sensor performance nuances can significantly influence image output, especially in demanding scenarios like low light or landscape photography.

• Olympus TG-860: 16MP resolution (4608 x 3456), TruePic VII processor; sensor area around 28.07 mm²; max ISO 6400; antialias filter present.
• Panasonic FZ100: 14MP resolution (4320 x 3240), Venus Engine FHD processor; sensor area slightly smaller at 27.72 mm²; max ISO 6400; antialias filter also present.

While both cameras feature nearly identical sensor sizes, the TG-860 edges out with a higher resolution sensor. However, resolution alone does not guarantee superior image quality. The TG-860’s TruePic VII processor generally delivers well-balanced color reproduction and noise reduction optimized for outdoor scenarios.

Conversely, the FZ100’s Venus Engine tends to produce sharper images at standard sensitivities and supports RAW file capture, a crucial advantage for enthusiasts wanting full control over post-processing workflows - a feature absent in the TG-860’s JPEG-only pipeline.

In practical testing, both cameras struggle with noise at ISO levels above 800, a limitation inherent to their small sensors. However, the FZ100 enables finer exposure control and shooting in RAW, offering advanced photographers more latitude to mitigate this through software.

Bottom line: If ultimate image quality and flexible post-production are priorities, the FZ100 has the edge due to RAW support and manual exposure modes. For casual shooting with instant JPEG delivery and vibrant colors, the TG-860 suffices.

Autofocus and Shooting Speed: Responsiveness Under Pressure

Fast, accurate autofocus (AF) and burst rates dramatically affect success in wildlife, sports, and street photography.

• TG-860: Uses contrast-detection AF with face detection; offers continuous AF and tracking; 7 fps continuous shooting (limited buffer); no manual focus.
• FZ100: Also contrast-detection based AF with face detection; supports single, continuous, and tracking AF modes; manual focus present; faster 11 fps burst rate.

In my hands-on testing with moving subjects, the FZ100’s faster burst speed and manual focus option allow for better tracking and capturing rapid sequences - essential when photographing fast wildlife or sports moments. The TG-860 performs adequately in controlled environments but occasionally displays sluggish AF response in low contrast or challenging lighting, which can be frustrating for action shots.
