Getting Acquainted: Physical Design and Handling

Before diving into image quality and performance, it’s essential to understand the ergonomics and handling of these cameras, since user experience often begins with how a camera feels in the hands and how intuitively the controls are arranged.

Compactness and Ergonomics

The Olympus XZ-10 is notably petite, embodying the essence of a pocketable compact camera with dimensions of 102 x 61 x 34 mm and a weight of merely 221 grams. In contrast, the Sony A37 significantly upsizes to 124 x 92 x 85 mm and weighs 506 grams, embodying the bulk associated with an APS-C DSLR, albeit in a relatively compact SLR form factor.

During field use, the XZ-10’s slim profile makes it an unparalleled choice for street photographers, casual travelers, or anyone requiring minimal intrusion into their surroundings. Its small body, however, limits the size and complexity of controls, which can be less satisfying for users accustomed to physical dials or the tactile feedback found in larger cameras.

Conversely, the Sony A37’s heft and shape yield a more substantial grip and better overall balance, especially when paired with longer lenses - advantageous for wildlife or sports photographers who demand stability during extended shooting. However, the compact SLR design with its deeper body thickness pushes it beyond the easy-pocketable realm.

Controls and Interface Layout

Both cameras offer fully manual exposure modes including aperture and shutter priority, critical for enthusiasts targeting creative control. The XZ-10 features a fixed 3-inch touchscreen with a generous 920k-dot resolution, facilitating intuitive point-and-shoot operations and focus selection. Notably, the screen is fixed, which restricts shooting flexibility in awkward angles, but its touchscreen responsiveness is commendable.

The A37 counters with a slightly smaller 2.6-inch tilting LCD at 230k dots - considerably lower resolution - without touchscreen capabilities. Instead, it relies on physical buttons and a traditional DSLR-style interface. This can be a double-edged sword: physical controls provide more tactile confidence during rapid adjustments, but beginners may face a steeper learning curve.

The absence of touchscreen on the Xperia A37 is mitigated somewhat by the presence of an electronic viewfinder (EVF) with 100% coverage and 1440-dot resolution, providing a vital compositional aid absent in the Olympus. The XZ-10 lacks any EVF, which potentially complicates outdoor shooting under bright sunlight.

Sensor and Image Quality: The Heart of the Matter

Arguably the most crucial aspect in camera evaluation is sensor performance, as it ultimately governs image fidelity, dynamic range, low-light capability, and resolution.

Sensor Size and Resolution Considerations

Here the Sony A37 decisively leads with a 23.5 x 15.6 mm APS-C CMOS sensor - a significant step above the Olympus XZ-10’s diminutive 1/2.3-inch backside-illuminated (BSI) CMOS sensor measuring 6.17 x 4.55 mm. This translates to an effective sensor area of 366.60 mm² for the Sony versus merely 28.07 mm² for the Olympus.

The larger sensor of the A37 naturally confers higher resolution at 16 megapixels (4912 x 3264 pixels), compared with the modest 12-megapixel output (3968 x 2976 pixels) of the XZ-10. More importantly, the physical pixel size is larger on the A37, which contributes to enhanced photon gathering capacity, impacting low-light noise and dynamic range.

In laboratory and real-world testing, the A37’s dynamic range measures approximately 12.9 EV stops, significantly surpassing the XZ-10’s performance, which was not formally tested by DxO but is objectively constrained by its small sensor. Similarly, the Sony facilitates native ISO sensitivity ranging from 100 to 25,600, enabling better noise control at higher sensitivities; the Olympus caps out at ISO 6400.

Image Processing and Raw Capabilities

Both cameras offer RAW capture, which is essential for professionals and enthusiasts who require maximum image editing latitude. The Sony’s RAW files offer greater tonal latitude and finer granularity, benefitting from the sensor prowess and advanced image processing pipeline, while Olympus RAWs tend to be more limited due to sensor size constraints.

Additionally, the Olympus XZ-10 applies an Anti-Aliasing (AA) filter, common in compact cameras to suppress moiré artifacts but at a slight cost to perceived sharpness. The Sony also includes an AA filter but benefits from higher native resolution and sensor technology advancements.

Autofocus Systems: Speed, Accuracy, and Tracking

The autofocus system is critical, particularly for action, wildlife, and event photography. While the Olympus XZ-10 fits into the compact category with contrast-detection AF, the Sony A37’s DSLR lineage includes phase-detection autofocus capabilities through its translucent mirror technology.

• Olympus XZ-10 AF: Contrast-detection system with 35 focus points, face detection enabled, but lacks continuous AF for video, and no animal or sophisticated subject tracking. The AF speed is moderate, adequate for general handheld shooting or portraits but limited for fast-moving subjects.

• Sony A37 AF: Hybrid system combining phase-detection (15 focus points, 3 cross-type) and contrast-detection, offering faster acquisition and better tracking capability - although the model lacks full AF tracking found in some higher-end models. The SLT (single-lens translucent) mirror enables continuous autofocus during live view and video, a benefit for hybrid shooters.

In real-world trials, the Sony A37's AF system felt notably more responsive and reliable in dynamic scenarios such as sports or wildlife, maintaining focus with better accuracy and allowing faster shooting sequences (up to 6 fps) compared to the XZ-10’s 5 fps burst with less consistent focus tracking.
