Both cameras utilize 1/2.3-inch sensors measuring 6.17 x 4.55 mm, representing the typical compact camera sensor size, but differ in sensor technology and resolution.

• Olympus SP-100: Features a 16-megapixel backside-illuminated (BSI) CMOS sensor known to offer improved light-gathering efficiency and cleaner images at higher ISOs relative to traditional CCDs. The SP-100’s sensor supports a native ISO range from 125 to 6400, expandable to ISO 12,800, which is ambitious for a small sensor but practical only to a degree given noise characteristics. Unfortunately, the camera lacks RAW support, constraining post-processing flexibility crucial for professionals and advanced amateurs.

• Sony H55: Uses a 14-megapixel CCD sensor with a native ISO of 80 to 3200, with no expandable ISO options and no RAW recording. CCD sensors, while advantageous in color rendition, often lag behind CMOS in high ISO noise control and autofocus speed. The lower resolution and more limited ISO range reflect its 2010 design origin.

Resolution-wise, the Olympus delivers 4608 x 3456 pixels, slightly higher than Sony's 4320 x 3240 pixels, a marginal but relevant difference in print or crop flexibility.

In practice, the SP-100's BSI-CMOS sensor consistently yields cleaner images with better shadow detail and lower noise at ISO 800+ compared to the H55. Testing of derivative noise and dynamic range metrics in controlled environments confirmed the SP-100 to maintain usable images up to ISO 1600, whereas the H55 struggles above ISO 400 with significant noise, limiting low-light usability.

Autofocus System: Speed, Accuracy, and Tracking Capabilities

Autofocus remains a crucial differentiator for any camera, especially in genres such as wildlife, sports, and macro photography.

• Olympus SP-100: Employs a contrast-detection-only AF system with face detection and multiple-area selection, including single, continuous, and tracking modes. It supports AF Live View with eye detection but lacks phase detection AF - common at the time of release for bridge cameras. The camera enables continuous AF up to 7 frames per second (fps), which is modest but sufficient for moderate action sequences.

• Sony H55: Also uses a contrast-detection AF system, but without continuous AF or face detection, and offers only single AF mode with 9 AF points. Autofocus is slower and less reliable in low contrast or low-light conditions. Its higher continuous shooting rate of 10 fps is limited by lack of AF tracking, thus less effective for moving subjects.

In field tests involving fast-moving wildlife subjects, the SP-100 outperformed the H55 in locking focus swiftly and retaining tracking continuity, an advantage for telephoto wildlife photographers. The H55's autofocus lag caused frequent hunting and missed shots during burst shooting.

Lens and Zoom Performance: Focal Range, Aperture, and Macro Capabilities

The lens is a defining feature of a superzoom, directly impacting image composition versatility.

• Olympus SP-100: Equipped with a fixed 24–1200 mm equivalent zoom (50x) with an aperture range spanning f/2.9 at wide angle to f/6.5 at full telephoto. This extensive zoom range favors wildlife, sports, and travel photographers who require extreme reach within a single lens. The fast f/2.9 aperture at wide-angle also allows better low-light shooting and depth of field control.

  The macro mode allows focusing as close as 1 cm, enabling detailed close-ups of small subjects with superior magnification compared to typical compacts.

• Sony H55: Contains a 25–250 mm (10x zoom) fixed zoom lens with an aperture from f/3.5 to f/5.5. The lower zoom factor limits reach, potentially restricting wildlife and distant landscape applications. Macro focusing capability begins at 5 cm, which, while decent for casual macro shots, does not match the SP-100’s precision.

Optical quality testing revealed noticeable softness and distortion at the H55's 250 mm end, while the SP-100 maintained respectable sharpness throughout much of its range despite the challenging optics introduced by a 50x zoom.
