The OLED interface menus depend on a three-way rocker for navigation, requiring menu dives for advanced parameter tweaks. This can interrupt shooting flow. The camera supports exposure compensation, manual exposure modes (shutter, aperture priority, full manual), and basic bracketing options, but offers no illuminated buttons or shortcut customization.

• Sony NEX-5R: The NEX-5R incorporates the Bionz processor, paired with a touchscreen that replaces many traditional controls, fostering a configurable and intuitive user interface. The shutter dial alongside programmable Fn button and virtual control wheel accessible on the screen enhances rapid adjustments. Advanced autofocus area selection and drive modes are directly accessed through touch menus or physical buttons, markedly improving on Olympus’s less accessible control scheme.

Overall, the Sony’s hybrid physical-touch interface provides superior agility and control granularity in real-world shooting. However, purists favoring tactile dials may prefer Olympus’s simpler manual control approach despite the trade-off in interaction speed.

Sensor Technology and Image Quality: Measuring Photographic Fundamentals

Image sensor characteristics underpin a camera’s capability to render resolution, dynamic range, color fidelity, and high ISO performance.

• Olympus PEN E-PL1s Sensor Overview: The PEN uses a 12MP Four Thirds CMOS sensor (17.3x13 mm). This smaller sensor size results in a 2.1x crop factor that affects field of view and depth-of-field characteristics. The TruePic V processor attempts noise reduction and sharpening but is limited by older sensor technology resulting in moderate high ISO quality with a maximum native ISO 6400.

• Sony NEX-5R Sensor Overview: The NEX-5R’s 16MP APS-C CMOS sensor (23.4x15.6 mm) is physically larger with about 62% more sensor surface area, affording improved light gathering and lower noise. Native ISO extends to 25600, enabling cleaner high ISO imagery. Additionally, the Sony sensor benefits from a back-illuminated design that enhances low light performance and dynamic range.

Empirical Testing Results

• Dynamic range: Sony leads with ~13.1 EV versus Olympus’s untested but practically narrower range expected from Four Thirds sensors.
• Color depth: Sony excels at 23.7 bits over Olympus’s non-DxO-tested unit, indicating richer color gradation.
• Noise performance: Sony maintains usable image quality beyond ISO 3200, whereas the E-PL1s degrades sharply above ISO 1600.

While the Olympus sensor suffices for well-lit conditions, landscapes, and casual indoor photography, Sony’s sensor architecture notably better suits demanding lighting and professional workflows requiring cleaner files and broader tonal flexibility.

Display and Viewfinder: Evaluating Composition Tools

The ability to confidently frame and review images directly impacts shooting efficiency and precision.

• Olympus PEN E-PL1s: Featuring a 2.7" fixed HyperCrystal LCD with low 230k-dot resolution, the PEN’s screen is challenging to interpret under bright ambient light, and the lack of articulation limits framing angles. Absence of a built-in electronic viewfinder (EVF) constrains composition flexibility, relegating framing options to screen use or optional external EVFs, reducing spontaneous shooting capabilities.

• Sony NEX-5R: The 3.0" tilting TFT LCD boasts a 920k-dot resolution and responsive capacitive touchscreen. The “tilt up 180°” ability facilitates high, low, and selfies framing positions, instrumental for street, travel, and video work. Like Olympus, it lacks a built-in EVF but supports optional external EVF accessories; however, the versatile LCD largely compensates for this.

The disparity in screen specifications and articulation tilts advantage decidedly toward the Sony NEX-5R for photographers seeking intuitive, flexible composition aids and quicker focus confirmation.

Autofocus System: Speed, Accuracy, and Tracking Capabilities

Autofocus (AF) efficiency underpins success in action-oriented genres, macro precision, and even portraiture for sharp critical focus, especially eye detection.

• Olympus PEN E-PL1s: Uses 11 contrast detection AF points with face detection enabled. Lacks phase detection, thus AF acquisition and tracking suffer in lower light and moving subjects. Continuous AF mode works but is noticeably slower relative to modern systems. Eye detection autofocus is absent, limiting portrait precision.

• Sony NEX-5R: Implements a hybrid autofocus system with 99 phase-detection points supplemented by contrast detection. This mix yields substantially faster AF acquisition times (often <0.15s) and superior tracking of moving subjects. Though lacking native eye AF, multi-area AF and center AF with face detection deliver reliable focusing during portraits and general shooting.

In practical wildlife, sports, and street scenarios, Sony’s autofocus system outperforms the Olympus’s system through speed and accuracy, reducing missed shots under challenging conditions.

Burst Shooting and Buffer: Capturing Action Moments

A camera’s frame rate and buffer depth directly correlate with its ability to seize decisive moments in fast-paced photography.

• Olympus PEN E-PL1s: Provides a continuous shooting speed of 3 fps with limited buffer depths. This restricts the camera’s relevance for sports, wildlife, or other rapid-fire shooting scenarios.

• Sony NEX-5R: Offers up to 10 fps continuous shooting, an exceptional rate for its class and generation. The buffer can handle several dozen compressed RAW frames, enabling bursts of action to be reliably captured.

Therefore, sports photographers or wildlife enthusiasts prioritizing burst capabilities will find the Sony’s performance superior by a large margin.

Lens Ecosystem and Compatibility: Extensibility and Creative Flexibility

The system lens mount and available optics impact versatility and future-proofing potential.

• Olympus PEN E-PL1s: Uses the Micro Four Thirds mount, a widely adopted standard backed by Olympus, Panasonic, and third-party manufacturers. With over 100 native lenses available ranging from ultra-wide to super-telephoto, this system provides ample choices for portraits, macro, landscape, and telephoto applications. The 2.1x crop factor implies that existing lenses behave as telephoto equivalents, advantageous for wildlife pictures.
