Sensor and Image Quality: Four Thirds vs. 1/2.3" BSI-CMOS

Central to image quality is sensor design. The Olympus E-450 sports a 10-megapixel Four Thirds CMOS sensor with dimensions of 17.3 x 13mm (224.9 mm² sensor area), coupled with Olympus’ TruePic III image processor, producing images at 3648x2736 resolution with a native ISO range of 100 to 1600. This larger sensor size in the Four Thirds format generally facilitates better dynamic range and improved low-light performance compared to smaller sensors.

The Sony QX10 uses an 18-megapixel 1/2.3" BSI-CMOS sensor sized 6.17 x 4.55mm (28.07 mm²) with a maximum image resolution of 4896x3672 and ISO range extending up to 3200. While boasting higher nominal megapixels, the smaller sensor area limits light-gathering capability and dynamic range, especially in low-light scenarios.

Quantitative analysis from DxOMark rates the E-450 with an overall score of 56, color depth at 21.5 bits, dynamic range at 10.5 EV, and low light ISO performance rated at ISO 512. The QX10 lacks official DxOMark data, but tests and sample images confirm expected limitations inherent to its sensor size - exhibiting increased noise at higher ISO settings and restricted latitude for heavy post-processing.

This marked difference is crucial for photographers prioritizing image quality, creative latitude, and larger prints.

Sensor size and resolved detail directly influence low light capability and dynamic range.

Autofocus and Shooting Experience: Precision vs. Convenience

The Olympus E-450 employs a hybrid autofocus system with three phase-detection and contrast-detection points, including multi-area and selective AF modes, but notably lacks face or eye detection and tracking capabilities. In practical terms, autofocus is responsive and accurate for static subjects and moderate action but can struggle with fast-moving subjects or weak light. Continuous autofocus is supported but limited.

Sony’s QX10 leverages contrast-detection AF aided by an app-based interface, featuring face detection but no continuous AF or animal eye detection. Given the lens’s integrated 10x zoom (25-250mm equivalent focal length), it offers flexible composition options through optical zoom, though autofocus speed and accuracy lag behind DSLR standards, which impacts candid or fast action shots.

Regarding burst rates, the E-450 can shoot up to 4 FPS, suitable for entry-level sports or wildlife attempts, while the QX10 does not specify burst capabilities, focusing instead on casual shooting.
