Sensor Technologies and Image Quality: A Technical Divergence

The foundational technical distinction here lies in sensor size and technology, leading to pronounced differences in image quality, noise performance, and depth of field rendering.

The Olympus’s 1/2.3" CCD sensor measures a mere 6.08 x 4.56 mm (sensor area ~27.7 mm²) with a 10-megapixel resolution cap (3648 x 2736 pixels). As a point-and-shoot sensor type, it naturally trades off dynamic range and low-light sensitivity for compactness and cost-efficiency. Olympus employs a fixed lens with a 5.9x crop factor equivalent focal length of 38-114 mm and max apertures ranging F3.5–F5.0, inherently limiting shallow depth of field and bokeh effects.

Conversely, the Sony NEX-3 boasts a considerably larger APS-C sized CMOS sensor with dimensions 23.4 x 15.6 mm (sensor area ~365 mm²) and 14 megapixels resolution (4592 x 3056 pixels), roughly 13 times the surface area of the Olympus sensor. This significant increase translates directly into superior low-light capability, dynamic range, color depth, and detail retention. Notably, the Sony benefits from the mature Bionz image processor and is paired with a vast lens ecosystem supporting manual focus, delivering creative flexibility few compacts match.

While the Olympus is limited to JPEG-only outputs and capped at ISO 1600 native, the Sony supports RAW recording, maximum ISO sensitivity up to 12800 native, and custom white balance settings, empowering higher-quality post-production workflows.

Viewing and Interface: Balancing Simplicity and Control

The Olympus features a fixed 2.5-inch LCD with 230k-dot resolution, providing a basic but adequate viewfinder replacement for composing shots outdoors. Meanwhile, the Sony leverages a larger 3-inch TFT Xtra Fine LCD with tilting mechanism and a higher 920k-dot resolution, enhancing framing comfort in diverse shooting angles and lighting.

Practically, the Sony’s LCD enables clearer image review and manual focus accuracy, critical to mirrorless operation, whereas the Olympus’s fixed screen and lack of live optical/electronic viewfinder align with its straightforward point-and-shoot use cases.

Autofocus and Speed: Precision Versus Simplicity

In terms of autofocus, the Olympus 550WP relies on contrast-detection AF with no face detection, no continuous AF, and no multi-area AF capabilities. This simplifies operation but limits performance on moving subjects or complex scenes.

In contrast, the Sony NEX-3’s AF system incorporates 25 focus points employing contrast-detection with face detection support and selectable multi-area focusing, significantly enhancing focus accuracy and speed, especially beneficial in portrait, wildlife, and street scenarios. Continuous AF support and burst shooting at up to 7 fps put the Sony well ahead for action photography.

Practical Photography Genres: Head-to-Head

To better appreciate each camera’s suitability, let’s dissect their performance across various photography disciplines.

Portrait Photography

The Olympus’s small sensor and limited aperture range restrict creative control over depth of field and background separation. Skin tones remain adequate in natural light but can appear less nuanced in shadow detail or highlight transitions, a consequence of limited dynamic range. The lack of face detection or eye AF further diminishes focus accuracy on moving subjects or candid portraits.

Conversely, the Sony’s APS-C sensor yields pleasantly smooth bokeh and precise skin tone rendition, with face detection AF significantly aiding sharp focus on eyes. The wide array of compatible fast prime lenses (e.g., Sony 50mm f/1.8 OSS) allows photographers to achieve professional-level shallow depth of field effects and subtle skin texture reproduction, making the NEX-3 a markedly superior portrait tool.

Landscape Photography

Landscape shooters demand high resolution, dynamic range, and weather durability. The Olympus, while compact and partially weather-sealed, is not fully ruggedized and lacks true environmental sealing. Its 10 MP sensor suffices for casual landscapes but shows limitations in shadow recovery and highlight clipping. The fixed 38-114 mm lens range is less ideal for wide vistas needing ultra-wide focal lengths.

The Sony NEX-3, despite lacking weather sealing, offers higher resolution (14 MP) and broader dynamic range (12.0 EV on DxOMark), facilitating capture of complex tonal gradations in skies and foliage. Interchangeable lenses include numerous ultra-wide angle options (e.g., Sony 16mm f/2.8). Thus, landscape photographers benefit from enhanced detail and compositional flexibility.

Wildlife Photography

Wildlife demands rapid autofocus, telephoto reach, and burst shooting speed. The Olympus’s slow contrast-detection AF and lack of continuous AF or tracking render it unsuitable for capturing fast-moving animals. The 114 mm equivalent max focal length is short for distant subjects.

The Sony NEX-3, while not a dedicated sports camera, offers 7 fps shooting and 25 AF points with multi-area focus, significantly improving success rates on moving wildlife. When paired with telephoto lenses (e.g., Sony 55-210mm f/4.5-6.3 OSS), it becomes a practical choice for entry-level wildlife shooters needing affordability and image quality over speed.

Sports Photography

Neither camera is tailored to high-speed sports. The Olympus’s limited frame rate and slow AF mean crucial moments are likely missed. The Sony’s 7 fps burst and AF options marginally improve capability but still lag behind professional APS-C DSLRs and mirrorless models with dedicated phase-detection AF systems.

Street Photography

Portability and discretion favor the Olympus with its compact silhouette and negligible shutter sound, ideal for candid urban shooting. However, the small sensor limits image quality in challenging light.

The Sony’s mirrorless design is larger but still compact relative to DSLRs, offering silent shooting modes and better low-light performance (ISO 12800 max), beneficial for street photographers aiming for image quality and versatility without drawing attention.
