At the core of any photographic tool is the sensor, dictating resolution, dynamic range, color fidelity, and ISO performance. These two cameras utilize fundamentally different sensor platforms, which shapes their imaging characteristics.

• Olympus E-PL1 offers a 12MP Four Thirds CMOS sensor measuring 17.3 x 13 mm (224.9 mm² sensor area) with a 2.1x crop factor. The sensor is paired with the Truepic V processor. It supports ISO 100–3200, with sensor-based stabilization. Tests reveal a DxO Mark overall score of 54 with color depth at 21.5 bits, and dynamic range reaching 10.1 EV. Low-light ISO performance is capped around 487.

• Sony NEX-5 sports a larger 14MP APS-C CMOS sensor sized 23.4 x 15.6 mm (365 mm² sensor area), along with the Bionz image processor. Its sensor provides a 1.5x crop factor, extending the native ISO range from 200–12,800, reflecting significantly better high-ISO usability. The DxO overall score is 69, with higher color depth (22.2 bits) and a greater dynamic range of 12.2 EV, accompanied by a low-light ISO rating near 796.

These objective measurements translate into noticeably superior color gradation, shadow recovery, and noise control on the NEX-5, especially in challenging lighting or overexposure-critical landscape imagery.

Rear Screen and Live View Experience

Live view composition and reviewing images benefit hugely from the quality and flexibility of the rear LCD screen.

• The Olympus E-PL1 uses a fixed 2.7-inch HyperCrystal LCD with anti-reflective coating but modest 230K pixel resolution. This made detailed previewing and manual focus confirmation more demanding, reducing confidence during macro or portrait work where precision is critical.
• Conversely, the Sony NEX-5 delivers a 3-inch tilting LCD at 920K resolution. This design enhanced visibility in bright conditions and enabled low-angle shooting beneficial for street and nature photography. The sharper screen provided more accurate histogram and highlight clipping feedback during real-time exposure adjustments.

The NEX-5’s tilting mechanism also increased compositional versatility without external accessories, a considerable advantage for candid capture and videography.

Autofocus System Performance and Speed

Autofocus efficiency impacts every genre from wildlife to sports and macro. Both cameras rely on contrast-detection autofocus, but implementation varies.

• Olympus E-PL1 features 11 focus points with face detection capabilities but lacks advanced tracking algorithms. The system shows competent single-shot AF performance but slower responsiveness in continuous and low-light scenarios, affecting subjects in motion such as athletes or birds.
• Sony NEX-5 offers 25 AF points with multi-area and selective autofocus control but without face or eye detection. Its faster acquisition speed and 7 fps burst shooting allowed superior capture of fleeting moments despite less sophisticated tracking.

In field tests, the NEX-5 notably reduces hunting and focus lag, especially when paired with Sony’s fast prime lenses. The E-PL1’s stabilizer partly compensates by allowing slower shutter speeds without blur but cannot emulate the NEX-5's frame rate for fast action.

Image Stabilization and Flash Capabilities

Image stabilization assists photographers in handholding lenses at slower shutter speeds and is essential for macro and low-light work.

• The Olympus E-PL1 incorporates sensor-based In-Body Image Stabilization (IBIS), providing up to 3 stops of shake reduction with any lens mounted on its Micro Four Thirds mount. This feature greatly benefits handheld shooting and video stabilization, especially when using adapted manual-focus lenses.
• In contrast, the Sony NEX-5 does not include in-camera stabilization, shifting stabilization responsibility entirely to lenses, which are relatively sparse for the E-mount in 2010’s early days.

In terms of flash, the E-PL1 includes a built-in pop-up flash effective within 10 meters, while the NEX-5 lacks any integrated flash but supports dedicated external units with extended range (up to 12 meters), appealing to those seeking higher flash output.

Video Functionality and Multimedia Usage

Video has become a critical feature even in entry-level mirrorless cameras, influencing purchasing decisions significantly.
