In general, these compact sensors exhibit limitations in dynamic range, noise performance, and color depth when compared to larger interchangeable lens cameras. The maximum ISO is capped at 1600, with no RAW support, restricting post-processing latitude. The CCD technology, while standard in compact cameras of that era, cannot rival modern CMOS designs in signal-to-noise efficiency.

The Panasonic G100 uses a Four Thirds sensor (17.3 x 13 mm) with approximately 225 mm² of surface area, significantly larger than the Olympus. This 20-megapixel CMOS sensor offers greater resolution, superior dynamic range, higher native ISO up to 25,600, and crucially supports RAW files, allowing photographers full control over tone mapping and noise reduction workflows. The anti-aliasing filter reduces moiré while maintaining sharpness. This sensor’s size and architecture make it highly versatile across demanding photographic genres.

From a technical perspective, the Panasonic's sensor advantage translates directly into higher image quality, better low-light capability, less noise at elevated ISOs, and greater detail rendering - factors critical for professionals or enthusiasts aiming for high-fidelity results.

Autofocus Systems: Contrast-Detection Compact Meets Modern Hybrid AF

The Olympus 9000 relies solely on a contrast-detection AF system with no phase-detection, face detection, or tracking functionalities. Focus points are unspecified and limited. Additionally, autofocus speed is measured but generally slow compared to modern standards, sometimes leading to hunting in low-contrast or low-light scenarios. The lack of manual focus further restricts control and tackling challenging subjects such as macro close-ups or distant wildlife.

In contrast, the Panasonic G100 incorporates a hybrid AF system with 49 focus points, majority contrast-detection based, supported by on-sensor phase-detection pixels to enhance speed and accuracy. It includes advanced face detection but lacks animal eye AF (a minor drawback for wildlife portraiture). The camera supports continuous AF, AF tracking, selective AF area, and touch AF on the articulated LCD, facilitating precise targeting and reliable focus tracking in fast-moving conditions. Focus bracketing and stacking features enable macro photographers additional precision options.

Practically, the Panasonic’s autofocus system outperforms the Olympus by a wide margin, enabling confident focus acquisition in diverse conditions including sports, wildlife, and macro, which the Olympus compact would struggle to manage effectively.

Lens System and Focal Range: Fixed Zoom and Versatile Interchangeability

The Olympus Stylus 9000 features a built-in, non-removable 28–280mm equivalent zoom lens with a maximum aperture range of f/3.2–5.9. This wide-to-telephoto range is convenient for general-purpose snapshots but with relatively slow aperture values, limiting background separation and low-light capability. The absence of expandable optics or close focusing beyond a 1 cm macro limit further restricts creative flexibility.

Alternatively, the Panasonic utilizes the Micro Four Thirds mount, granting access to a vast ecosystem exceeding 100 native lenses, ranging from ultra-wide primes to super-telephoto zooms. This adaptability allows photographers to tailor their setups to specialized needs from fast portraits with wide apertures to wildlife telephoto reach and dedicated macro optics. The camera supports lenses with optical image stabilization to compensate for camera shake. This dynamic lens compatibility significantly extends the G100’s creative and technical possibilities.

Beginners or enthusiasts prioritizing an all-in-one, straightforward solution will find the Olympus compact’s fixed lens advantageous for simplicity and portability. Professionals or advanced amateurs will benefit from the Panasonic’s modular lens strategy and higher optical performance potential.
