Comparing Sony Cyber-shot DSC-H55 and Sony Cyber-shot DSC-RX10 II: A Definitive Guide for Discerning Photographers

As someone who has spent over 15 years extensively testing and analyzing cameras from entry-level compacts to professional-grade systems, I recognize how pivotal it is to decode the nuances that distinguish seemingly analogous models - particularly within the same brand. In this detailed review, we will meticulously compare two distinct offerings from Sony’s Cyber-shot lineup: the modest Sony H55 compact bridge camera launched in 2010, and the robust Sony RX10 II, introduced five years later as a large sensor superzoom bridge camera.

Although both are Cyber-shot models, they serve remarkably different use cases and target very different photographic audiences. My hands-on testing, calibrated sensor lab measurements, and real-world shooting experience underpin this comprehensive comparison. We’ll cover all vital aspects: from sensor technology, image quality, autofocus capabilities, and ergonomics, to specialized genre performance and overall value proposition. The goal is to empower photographers at various skill levels - with practical, actionable intelligence - to confidently identify which camera best suits their creative and technical aspirations.

Visualizing Physical Differences: Size, Design, and Handling

One of the immediate and most practical distinctions between the Sony H55 and RX10 II lies in their form factors. The H55 is a compact point-and-shoot styled bridge camera, whereas the RX10 II advances toward full DSLR ergonomics with a large, protruding lens and a significantly bigger body.

Sony H55 vs Sony RX10 II size comparison

Sony H55: Very pocketable and lightweight at only 200 grams with physical dimensions of 103 x 58 x 29 mm, the H55 excels in portability. Its small size makes it an attractive choice for casual travel or everyday carry, but can feel limiting in hand, particularly for users with larger palms or those who demand extensive manual control.

Sony RX10 II: At 813 grams and measuring 129 x 88 x 102 mm, this camera is substantially bulkier and heavier. This weight penalty buys considerably improved handling ergonomics reminiscent of DSLR-type cameras, with a deeper grip and strategically placed buttons that support sustained handheld shooting sessions, including on-the-fly adjustments during dynamic scenarios like wildlife or sports photography.

Despite the RX10 II’s heft, the build quality is robust and reassuringly solid, featuring partial weather sealing absent in the H55 - a critical factor if shooting outdoors in mixed or harsh weather conditions. The H55’s compactness sacrifices sealing entirely.

This physical size difference reflects the philosophical divergence: snapshot convenience versus advanced creative control.

Layout and Interface: Navigating Controls and Usability

Looking at the top and rear control layouts reveals the degree to which Sony intended to prioritize manual operation and quick access to key functions on each model.

Sony H55: The control set is minimalistic, geared toward simplicity. There is no mechanical shutter priority, aperture priority, or manual exposure modes, which significantly constrains creative exposure control. The menu and dial systems are straightforward but do not cater well to experienced users demanding full customization or rapid setting adjustments. The absence of an electronic viewfinder (EVF) forces users to depend entirely on the fixed, low-resolution 3.0-inch LCD for framing.

Sony RX10 II: Offers a DSLR-like control experience with dedicated dials for shutter speed, aperture, exposure compensation, and mode selection, alongside customizable buttons. It incorporates a high-resolution EVF delivering 2,359K dots with 100% frame coverage - a major advantage for precise composition and working under bright sunlight. The rear 3.0-inch LCD also improves considerably on resolution with 1,229K dots and is tiltable for creative shooting angles.

This deeper tactile and visual control system situates the RX10 II as a tool for photographers who prioritize swift, intuitive operation and fine exposure fidelity.

Sensor Technology and Its Impact on Image Quality

Arguably the most critical factor differentiating these two cameras is their sensor technology, which profoundly influences image quality across every genre from landscapes to portraits.

Sony H55 vs Sony RX10 II sensor size comparison

Sony H55 Sensor:

  • Type: 1/2.3” CCD sensor measuring 6.17 x 4.55 mm (28.1 mm²)
  • Resolution: 14 megapixels (4320 x 3240 pixels)
  • ISO Range: 80 to 3200 (native)
  • Raw Support: No

This small sensor size inherently limits the dynamic range and low-light performance. CCD sensors were once favored for color fidelity but now lag behind newer CMOS designs in noise management and speed. The H55’s native ISO maxes out at 3200, but usable image quality above ISO 400 is considerably compromised by noise and loss of detail. The absence of raw shooting further restricts post-processing flexibility.

Sony RX10 II Sensor:

  • Type: 1” BSI-CMOS sensor measuring 13.2 x 8.8 mm (116.16 mm²)
  • Resolution: 20 megapixels (5472 x 3648 pixels)
  • ISO Range: 64 to 25600 (expanded)
  • Raw Support: Yes

The RX10 II’s larger 1” sensor offers more than 4x the sensor area of the H55, translating into superior light gathering, wider dynamic range (measured at 12.6 stops by DxO Mark), and exceptional detail retention throughout its ISO range. The back-side illumination (BSI) technology doubles down on sensitivity improvements, delivering cleaner images in dimly lit environments and smoothing high ISO grain structure.

Raw support enables professionals and serious enthusiasts to extract maximum image quality by fine-tuning exposure, color balance, and noise reduction in post-processing. The RX10 II’s sensor technology effectively places it in a class vastly superior to that of the older H55, making it a more versatile and future-proof choice.

Autofocus and Shooting Performance Under Real Conditions

Despite their different release years, understanding autofocus systems and burst shooting capabilities remains essential for practical evaluation.

Sony H55 Autofocus:

  • Contrast-detection AF with 9 focus points (including a central point)
  • Single AF mode only; no continuous tracking or advanced subject recognition
  • Face detection unavailable

Sony RX10 II Autofocus:

  • Contrast-detection AF with 25 points
  • Continuous AF with subject tracking and face detection
  • Improved responsiveness and accuracy for fast-moving subjects
  • Eye AF supported for portraits (though animal eye AF is missing)

Shooting Speed:

  • H55: 10 frames per second continuous shooting, albeit with limited buffer depth and no AF tracking
  • RX10 II: 14 fps continuous burst, combined with continuous AF tracking, ideal for capturing action sequences such as sports or wildlife

In practical field tests, the H55 struggles to maintain focus reliability on erratically moving subjects, and its fixed-lens inability to accommodate telephoto reach beyond the 10x zoom may be cumbersome. The RX10 II, conversely, excels at swiftly locking onto subjects with minimal hunting, even in low-contrast or low-light scenes, a testament to its more advanced processor (Bionz X) and autofocus algorithm enhancements.

Specialized Genre Performance: Which Camera Excels Where?

Achieving a well-rounded understanding requires examination of their real-world suitability across the spectrum of photographic disciplines.

Portrait Photography

Portraiture demands natural skin tones, precise eye focus, and attractive background separation.

  • Sony H55: Limited by small sensor and lack of manual aperture control, resulting in predominantly deep depth-of-field images with minimal bokeh separation, plus no eye-detection AF. Skin tones appear adequate under good lighting but can lack subtlety in complex lighting.
  • Sony RX10 II: Its bright f/2.8 constant aperture across the zoom range allows shallow depth-of-field effects with pleasing bokeh, while face and eye detection AF ensures critical focus. Larger sensor size delivers smoother skin tones and finer gradations.

Verdict: RX10 II firmly outperforms for creative portraits that demand professional aesthetics.
