Ето че когато става дума за сравнение на един и същи клас апарати и се стигне до често обсъжданият "огромен недостатък" на Паналайката - високите нива на шум, се оказва, че всъщност именно ФЗ18 се представя най-добре сред съперниците:
At ISO 64, the Fujifilm Finepix S8000fd has Extremely High (1583) Resolution, and Low (1.7) Noise. At ISO 100, Noise rises a touch to Moderately Low (2.1). At ISO 200, Noise is Moderate (2.9). At ISO 400, Noise is Unacceptable (3.0); aggressive noise control kicks in at ISO 800, bringing it back down to Moderately Low (2.4). At ISO 1600, noise is again Unacceptable (4.0), with a significant Resolution drop to Acceptable (1150). Color accuracy is Extremely High (Average Delta E: 9.4, ISO 64, Auto White Balance.)
At ISO 50, the Olympus SP560UZ also has Extremely High (1660) Resolution and Low (1.7) Noise. Noise is also Low (1.7) at ISO 100. Noise is Moderately Low at ISO 200 (2.3). At ISOs 400 (2.4), 800 (2.4), and 1600 (2.8) Noise is Moderate. Resolution also drops dramatically at ISO 1600, to Unacceptable (900.) Noise is Unacceptable at ISO 3200 (3.1). Color accuracy is Excellent (Average Delta E: 7.7, ISO 50, Auto White Balance.)
At ISO 100, the Panasonic Lumix DMC-FZ18 has Excellent (1890) Resolution, with Low (1.7) Noise. Noise is Moderate at ISO 200 (2.4). Noise is Moderately Low at ISOs 400 (2.2), 800 (2.1), and 1250 (2.2) and Moderate at ISO 1600 (2.5.) At ISO 1600, Resolution drops to 1325 (Very High). Color Accuracy is Extremely High (Average Delta E: 8.1, ISO 100, Auto White Balance.)
For the absolute best image quality with all three of these cameras, we suggest shooting at the lowest ISOs possible, combined with image stabilization only when necessary. When it comes to higher-ISO performance, the Panasonic has the definite edge in both resolution and noise control. At ISO 400 and up, the Fujifilm seems to favor resolution over noise suppression, while the Olympus favors noise control over detail.
