Sensor Technology and Image Quality Fundamentals

Sensor architecture is the cornerstone of digital imaging. Let's examine both cameras' sensor particulars and how these influence image characteristics.

• Olympus E-520 features a Four Thirds CMOS sensor measuring 17.3 x 13 mm (sensor area: 224.9 mm²). Its 10 MP resolution outputs maximum image dimensions of 3648 x 2736 pixels. The sensor employs an anti-alias filter, influencing sharpness and moiré suppression. Max ISO caps at 1600 natively with a measured low-light ISO performance score of 548 (DxOMark).

• Samsung NX5 sports a larger APS-C CMOS sensor of 23.4 x 15.6 mm (365.04 mm²), yielding a significantly increased 15 MP resolution (4592 x 3056 pixels). This sensor also includes an anti-aliasing filter and extends ISO sensitivity up to 3200.

What to expect in practice:

The larger APS-C sensor in the NX5 inherently provides better noise performance, improved dynamic range potential, and greater subject-background separation when paired with fast optics - the hallmark benefits for portrait, landscape, and low-light photography. The effective crop factor of 1.5x allows use of lenses with a more familiar angle of view compared to the E-520's 2.1x multiplier, which can exaggeratedly narrow perspectives.

The E-520’s Four Thirds sensor, despite its smaller size, delivers competent image quality under good lighting due to Olympic’s Dual TruePic V+ image processor (unnamed in specs but core to color accuracy and processing speed). However, noise increases noticeably beyond ISO 800.

For pixel-level detail, the NX5’s higher resolution grants more cropping flexibility and larger print potential, which enthusiasts and professionals often demand.
