First Impressions: Design, Size, and Handling

A camera’s physical design directly influences shooting comfort, especially during prolonged sessions or travel. Both the Olympus E-P2 and Sony NEX-5T adopt classic rangefinder-style mirrorless bodies with minimalist aesthetics, but their ergonomic nuances merit close inspection.

Olympus E-P2 embodies a compact, retro design typical of Micro Four Thirds cameras of its time, weighing 355 grams with dimensions of 121x70x36mm. Its fixed 3-inch HyperCrystal LCD with anti-reflective coating delivers acceptable viewing angles but lacks articulation and touch responsiveness. Handling is complemented by sensor-based image stabilization, integral to Olympus bodies.

Sony NEX-5T, unveiled three years later, adopts a slightly smaller form factor at 111x59x39mm and weighs a lighter 276 grams, optimizing portability. It features a 3-inch tilting TFT LCD with touchscreen capabilities, tilt angles of +180° and -50°, and higher resolution of 922k dots, significantly enhancing framing flexibility, especially for vloggers and self-portraits.

In testing, the E-P2’s vintage control layout offers a tactile shooting experience but feels less modern compared to the NEX-5T’s responsive touchscreen interface and customizable buttons accessible on its top plate (detailed further below). While Olympus’s sensor-based stabilization lends handholding advantages, Sony’s lighter weight and screen articulation favor mobility-focused photographers.

Control Layout and Top-Plate Design: Intuitive or Overwhelming?

Control ergonomics not only affect ease of use but also fast operation in dynamic shooting scenarios. The Olympus E-P2 opts for simplicity with limited direct controls, relying on menus for exposure settings and shooting modes, whereas the Sony NEX-5T offers a more elaborate, user-friendly control scheme.

The NEX-5T incorporates a dedicated mode dial, a larger shutter button with a surrounding on/off switch, a control wheel, and multiple customizable buttons. This arrangement facilitates quick switching between aperture priority, shutter priority, and manual modes, valuable for photographers needing rapid adjustments.

Conversely, the E-P2, consistent with its entry-level positioning over a decade ago, has fewer dedicated external controls, demanding menu navigation for some settings, which can slow down workflow for users accustomed to direct access dials and buttons. The absence of illuminated buttons diminishes usability in low-light conditions.

Sensor Technology and Image Quality: Four Thirds vs APS-C

Sensor size and technology fundamentally dictate image quality potential - from dynamic range to noise handling and resolution.

Olympus’s E-P2 sports a 12MP Four Thirds CMOS sensor measuring 17.3 x 13 mm (224.9 mm² sensor area), while Sony’s NEX-5T houses a substantially larger 16MP APS-C CMOS sensor at 23.4 x 15.6 mm (365.04 mm²). This 62% increase in sensor area allows for larger photodiodes, improved light-gathering capability, and enhanced dynamic range.

According to DxOMark testing benchmarks and corroborated by practical experience, the NEX-5T exhibits:

• Higher overall image quality score (78 vs 56)
• Superior color depth (23.6 bits vs 21.5 bits), rendering more nuanced skin tones and landscapes
• Expanded dynamic range (13.0 EV vs 10.4 EV), critical for preserving highlights and shadow details in high-contrast environments
• Better low-light ISO performance (1015 vs 505), which translates to cleaner images at elevated sensitivities

While the E-P2 benefits from sensor-based image stabilization allowing slower shutter speeds without blur, the APS-C sensor’s inherent noise advantage makes it more adept for night, astro, and low-light photography.

Autofocus Systems: Navigating Focus Speed and Accuracy

Accurate and swift autofocus is essential across all genres, especially wildlife, sports, or street photography where decisive focus can make or break an image.

The Olympus E-P2 employs an 11-point contrast-detection AF system with face detection, but no phase-detection, limiting its autofocus tracking speed and reliability for moving subjects. The single continuous shooting speed of 3 fps further constrains its capacity for action photography.

The Sony NEX-5T’s 99-point hybrid autofocus with 25 cross-type phase-detect points dramatically improves speed and tracking accuracy. It supports continuous AF with face detection and eye detection - ideal for portrait photographers aiming for tack-sharp eyes. With a burst rate of 10 fps, the NEX-5T can capture fast action sequences more effectively.

Highlights:

The hybrid AF system in the Sony offers robust performance in wildlife and sports contexts, where precise subject tracking and high frame rates are paramount - strongly favoring the NEX-5T.

LCD Screens and Viewfinder Options: Critical Composing Tools

Optical and electronic viewfinders remain indispensable for critical composition beyond the LCD screen, especially in bright conditions.

Neither camera offers a built-in electronic viewfinder (EVF). However, the Olympus E-P2 supports an optional external EVF (sold separately), whereas the Sony NEX-5T lacks EVF compatibility but compensates with its superior touchscreen display.

The E-P2’s 3-inch 230k-dot fixed LCD is relatively dim and less responsive, limiting its usefulness in real-world shooting and live tracking. Meanwhile, the NEX-5T’s 3-inch 922k-dot tilting touchscreen affords much improved clarity, touch-focus capabilities, and the versatility to shoot from high or low angles comfortably. This is particularly advantageous in street and travel photography scenarios.

Lens Ecosystem and Compatibility: Expanding Creative Horizons

An extensive and mature lens lineup is crucial for adapting to varying creative demands.

Olympus’s Micro Four Thirds mount earned a significant early start and boasts over 107 native lens options, including compact primes and specialty optics from Olympus, Panasonic, and third parties. The lens ecosystem supports a two-times crop factor, allowing affordable telephoto reach, which benefits wildlife and sports shooters on a budget.

Sony’s E-mount system, while relatively newer around the NEX-5T’s release, already offered 121 lenses, spanning primes, zooms, and high-quality G and Zeiss options, with a crop factor of 1.5x. Though the E-mount initially focused more on APS-C glass, it has since evolved into a fully-fledged system supporting full-frame lenses, giving future upgrade paths.

In practical use, the Olympus system’s smaller sensor size allows for smaller, lighter lenses, while Sony’s APS-C lenses offer superior optical quality and wider apertures, facilitating better bokeh and low-light performance.

Battery Life and Storage: Staying Powered and Ready

For extended shooting sessions and travel excursions, battery endurance and flexible media options are vital considerations.
