Buttons are small and non-illuminated, limiting usability in dim conditions. The Sony H55 exhibits a more conventional compact camera layout with tactile controls, including a 9-point autofocus selector and visibility-oriented layout, albeit without touchscreen or top information display. The larger size benefits stability, especially when zoomed.

These form factors dictate use-case preferences: the VG-120 suits spontaneous street or travel shooting where discretion and lightness dominate; the H55 accommodates a wider range of shooting modes needing quicker, more precise handling.

Sensor Specifications and Image Quality Expectations

Both models utilize identical-sized 1/2.3" CCD sensors measuring 6.17x4.55 mm providing a total sensor area of approximately 28 mm² with a 14 MP resolution. Native ISO ranges start at 80 and extend up to 1600 for the VG-120 and 3200 for the H55.

CCD sensors traditionally emphasize color depth and dynamic range in well-lit conditions at the expense of higher noise levels in low-light compared to CMOS alternatives seen in modern cameras. Given the identical sensor size and technology, performance is closely matched, though Sony’s higher maximum ISO suggests attempts at improved versatility in low-light shooting.

Olympus deploys a TruePic III image processor, an entry-level engine of its generation, limiting post-processing speed and noise reduction adaptability. Sony’s Bionz processor similarly caters to its sensor class but enhances continuous shooting frames and internal debugging.

Olympus VG-120’s limited ISO ceiling of 1600 curtails effective low-light use, while the H55’s 3200 ISO allows marginally better sensitivity, though with increased noise.

Lens and Optical Characteristics: Zoom Range, Aperture, and Macro Capabilities

The VG-120’s fixed 26-130 mm equivalent lens, with a 5x optical zoom, offers a starting aperture of f/2.8 narrowing to f/6.5 at the tele end. Its prime attribute is relatively bright apertures at the wide angle for a compact, beneficial for gathering more light and shallow depth of field in portrait and general photography. The minimum macro focus distance is 7 cm, suitable for casual close-up shots.

Sony H55 has a shorter focal length at wide angle (25 mm equivalent), extending dramatically to 250 mm equivalent (10x zoom), nearly doubling the telephoto reach. Aperture ranges from f/3.5 to f/5.5, slightly slower than Olympus on the wide end but brighter at telephoto. Macro focusing improves to 5 cm minimum, advantageous for detailed close-ups or nature shots without needing additional accessories.

The Sony’s extended focal range and optical image stabilization oppose the Olympus’s brighter aperture advantage. Stabilization is notably absent from the VG-120, reducing handheld shooting efficacy beyond wide angles and in low-light conditions.

Autofocus Systems: Precision and Speed in Practical Shooting

Neither camera offers manual focus, reflecting their ultracompact to compact categorization and likely novice to enthusiast market positioning. Both rely on contrast-detection AF mechanisms, without phase-detection or hybrid capabilities.

The Olympus VG-120 supports multi-area autofocus with face detection, an asset for portraits and casual snapshots involving people. However, it lacks AF tracking, continuous AF, or selective focus-point control, noticeably restricting its usefulness in fast-moving scenarios such as wildlife or sports.

Sony H55 features a 9-point AF array with center-weighted and multi-area focus modes. Unfortunately, it does not incorporate face detection or eye-tracking, limiting convenience in portrait orientation. Continuous AF is also unavailable, but single AF acquisition is quicker and more reliable than the Olympus in our hands-on field tests.

Absence of continuous autofocus and focus tracking on both cameras impose challenges photographing dynamic subjects, though Sony’s more advanced AF array marginally improves accuracy and speed.

Display and User Interface: Viewing and Navigation

Both offer 3.0-inch fixed TFT LCD screens at a modest 230K-dot resolution, limiting the sharpness and color fidelity compared to higher-resolution modern models. Neither provides touch functionality.

The Olympus VG-120 offers live view without electronic viewfinder (EVF). Its UI is minimalistic, reflecting limited exposure control and fewer menu options. The Sony H55 similarly lacks an EVF but compensates with a slightly more intuitive menu system allowing custom white balance adjustments, which the Olympus omits.

Users desiring extensive control or interface customization will find both lacking, especially given the absence of exposure modes such as shutter or aperture priority.

Image Stabilization and Burst Shooting: Capturing Motion

Olympus VG-120 does not incorporate image stabilization, greatly affecting telephoto shooting and handheld low-light conditions. Its burst shooting capability is unspecified, suggesting no continuous shooting mode.

Sony H55 includes optical image stabilization, significantly enhancing sharpness at longer focal lengths, and provides a fast burst mode of 10 frames per second for short sequences. This affords superior capacity for capturing action and wildlife subjects.

Video Functionality and Multimedia Output

Video recording is similarly basic but with notable differences:

• Olympus VG-120 shoots 720p HD video at 30 or 15 fps using Motion JPEG format, resulting in larger file sizes and limited editing flexibility.

• Sony H55 also records 720p video at 30 fps but utilizes MPEG-4 compression, resulting in better compression rates and widely compatible output.

Neither model provides microphone or headphone ports nor advanced video features such as 4K recording or optical zoom during video. Both lack HDMI ports precluding direct HDMI output to external monitors.
