In terms of control layout, Olympus’s adoption of dedicated dials for shutter speed, aperture, exposure compensation, and a customizable function button positions it as a camera designed for enthusiasts and semi-pro users who appreciate tactile input and rapid settings access. The Sony model, by contrast, limits manual operation options, with no dedicated manual exposure mode or shutter/aperture priority - reflection of its entry-level orientation - with most functions automated.

Verdict: Ergonomically, the Olympus XZ-2 iHS clearly targets photographers looking for expertise-level control and comfort, while the Sony H55 emphasizes portability and simplicity, trading off some usability for compact convenience.

Behind the Lens: Optical Design and Zoom Capabilities

Lens technology directly influences image quality and creative freedom. Both cameras utilize fixed zoom lenses but with contrasting focal length ranges and apertures.

• Olympus XZ-2 iHS: Features a bright 4x optical zoom equivalent to 28-112 mm (multiplier 4.8x), with impressively fast maximum apertures from F1.8 at wide angle to F2.5 at telephoto. Such brightness benefits low-light shooting and depth of field control, enabling subject separation and creamy bokeh for portraits or close-ups. Remarkably, it supports ultra-close macro focusing down to 1 cm, facilitating fine-detail photography.

• Sony Cyber-shot DSC-H55: Sports a superzoom lens spanning 25-250 mm equivalent (10x zoom, multiplier 5.8x) but with slower maximum apertures ranging F3.5 to F5.5. While the extended zoom range provides greater telephoto reach - advantageous for wildlife or distant subjects - the narrower aperture sacrifices low-light performance and shallow depth of field capabilities. Macro focusing has a minimum distance of 5 cm, less accommodating for extreme close-ups.

The Olympus lens’s constant large aperture at the wide end aids creative control and image sharpness, whereas Sony’s extended focal length targets versatility, albeit trading off in brightness and bokeh potential.

Recommendation: For photographers valuing image quality, artistic control, especially portraits and macro, Olympus takes the lead; for those prioritizing zoom range for travel or casual telephoto use, Sony offers more reach.

Sensor Technology and Image Quality: CMOS vs CCD

A critical determinant of image fidelity is the sensor, and here the two models diverge substantially:

• Olympus XZ-2 iHS: Equipped with a 1/1.7” back-illuminated CMOS sensor measuring approximately 7.44 x 5.58 mm (area 41.52 mm²) with 12 megapixels resolution. This BSI CMOS sensor improves light-gathering efficiency, reducing noise and enhancing dynamic range. It supports RAW capture, allowing extensive post-processing latitude. According to DxOMark tests, it scores 49 overall, with excellent color depth (20.4 bits) and dynamic range (11.3 EV), and reasonable low-light ISO performance (rated 216).

• Sony Cyber-shot DSC-H55: Uses an older 1/2.3” CCD sensor sized 6.17 x 4.55 mm (28.07 mm²) with 14 megapixels. CCD sensors traditionally offer good color accuracy but lag in noise control, especially at higher ISO sensitivities. No RAW support limits flexibility for professionals. Sony’s sensor is not DxOMark tested but comparable sensors of the era exhibit lower dynamic range and higher noise at ISO above 400. Maximum native ISO tops at 3200, which, given the hardware, yields grainy images.

The CMOS sensor in the Olympus provides superior real-world image quality, along with better performance in variable lighting conditions and greater editing versatility due to RAW. The smaller, older CCD in the Sony suits mostly daylight and well-controlled situations.

Autofocus and Shooting Performance: Precision vs Simplicity

Autofocus (AF) effectiveness is pivotal across all photography genres - portrait, wildlife, sports, and more. Each camera’s autofocus system shows its intended user level:

• Olympus XZ-2 iHS: Leveraging 35 contrast-detection focus points with face detection, the AF system supports single-shot autofocus, basic tracking, but lacks phase-detection points. Although continuous AF is absent, manual focus override and peaking assist support precision focusing. Olympus’s sensor-shift image stabilization coupled with fast aperture lenses aids sharp capturing. While the continuous burst rate is unavailable, it compensates by focus accuracy critical in portraits and macro.

• Sony Cyber-shot DSC-H55: Employs a simpler 9-point contrast-detect AF with center-weighted emphasis, lacking face detection and AF tracking. No manual exposure control reduces user input options. Continuous shooting at 10 fps is a standout, facilitating action capture albeit resolution drops or buffering impacts long bursts.

Consequently, Olympus favors quality and focus precision, beneficial when compositional control is prioritized, while Sony offers rapid frame rates suitable for casual sports or street action but with limited subject tracking reliability.

User Interface: Viewing and Controls

Beyond hardware controls, LCD screens and viewfinders contribute to framing ease.

• Olympus XZ-2 iHS: Features a 3-inch tilting touchscreen with 920k-dot resolution, enabling high visibility, intuitive touch focus, and menu navigation. Lacking a built-in EVF but compatible with an optional electronic viewfinder accessory retains user flexibility. The touchscreen interface aligns with modern ergonomic trends favoring direct manipulation.

• Sony Cyber-shot DSC-H55: Offers a fixed 3-inch LCD at much lower resolution (230k dots), reducing detail visibility. No viewfinder available. The absence of a touchscreen demands reliance on button controls, which, although minimal, suffice for straightforward operation.

Clear screen detail and setup responsiveness on the Olympus enhance usability, especially in bright outdoors or complex shooting scenarios.

Image Stabilization: Sensor-Shift vs Optical

Both implement image stabilization to mitigate camera shake:

• Olympus XZ-2 iHS: Incorporates sensor-shift (in-body) stabilization, which corrects shake regardless of lens attached and works with all focal lengths, notably effective for video and macro.

• Sony Cyber-shot DSC-H55: Provides optical image stabilization integrated into the lens, useful primarily at telephoto lengths but less versatile than sensor-shift.

In practice, Olympus’s stabilization is more adaptable and potent, aiding diverse shooting styles including slower shutter speeds and video.
