Its mid-sized form factor supports substantial grip real estate, easing manual operation and stabilizing telephoto or heavier lenses. The body feels solid yet remains reasonably portable, suitable for enthusiasts valuing handling precision.

Pentax Efina, by contrast, is ultracompact at 87 x 54 x 21 mm and weighs just 91 g. Designed for supremely casual portability, it fits into the smallest pockets. This form factor trades manual control for simplicity, with limited physical buttons and a compact chassis that favors grab-and-go street and travel photography.

Ergonomically, the E-PL2 offers superior comfort and tactile control, including dedicated dials and customizable buttons, accommodating deliberate photographic workflows. The Efina’s minimal setup suits spur-of-the-moment captures but may frustrate users accustomed to manual exposure settings.

Control Layout and Interface Design: Access and Operation

Beyond mere dimensions, control layout directly impacts photographic responsiveness and customization potential.

The Olympus E-PL2 provides a traditional top-plate design featuring mode dials, shutter release, and exposure compensation controls. Back and top buttons map logically for quick access during shooting. Absence of touchscreen functionality is compensated by physical buttons responsive to tactile feedback, a preference for many professionals who require precision regardless of ambient conditions.

The Pentax Efina, lacking manual exposure modes and physical dials, uses basic button controls mostly oriented towards point-and-shoot use. The limited button count reflects its casual target audience, offering no exposure compensation or priority modes, further restricting user intervention.

For photographers prioritizing speed and control over automated simplicity, the E-PL2’s interface grants a tangible advantage, enabling nuanced adjustment without menu diving.

Sensor Technology and Image Quality: The Heart of Photography

A camera’s sensor determines base image quality, dynamic range, low-light capability, and resolution - key parameters for serious photographers.

Olympus E-PL2 employs a Four Thirds sized CMOS sensor measuring 17.3 x 13 mm with an effective resolution of 12 megapixels (4032 x 3024 pixels). The sensor benefits from CMOS advantages - a generally faster readout and better high ISO performance. The TruePic V image processor is optimized for noise reduction and color fidelity. DxOMark scores reflect a balanced performance with a color depth of 21.4 bits, dynamic range of 10.2 EV stops, and usable high ISO up to 6400.

In comparison, Pentax Efina utilizes a much smaller 1/2.3-inch CCD sensor measuring only 6.17 x 4.55 mm with an effective resolution of 14 megapixels (4288 x 3216 pixels). While higher in nominal pixel count, the sensor’s physical size inherently limits dynamic range and high ISO performance. Its CCD architecture favors color accuracy at low ISO but suffers from increased noise beyond ISO 400-800. The absence of RAW support further restricts post-processing latitude.

Practically, the E-PL2 delivers cleaner images, improved shadow recovery, and greater flexibility in low light or high contrast scenes. The Efina’s sensor is adequate for daylight casual use but will frustrate those seeking image quality beyond typical snapshots.

Viewing and Composing Images: Screen and Viewfinder Capabilities

Framing and reviewing images depend on the quality and usability of the rear LCD and available viewfinder systems.

The E-PL2 offers a 3-inch fixed HyperCrystal LCD with a modest 460k-dot resolution, treated with anti-reflective coating, providing decent visibility in most lighting conditions. Although it lacks a built-in electronic viewfinder, users can optionally attach one, a feature that aids composition when bright ambient light compromises LCD usability.

The Efina’s 2.5-inch TFT LCD of 230k-dot resolution is comparatively smaller and less detailed, which may hinder critical focus assessment and image review. The absence of any viewfinder limits compositional precision, especially outdoors under harsh sunlight.

Thus, shooters valuing image assessment accuracy and flexible framing methods will find the E-PL2’s screen offering superior usability, while the Efina remains basic.

Autofocus Systems: Speed, Accuracy, and Tracking

Autofocus proficiency greatly influences shot success across virtually all genres. Let’s dissect their AF capabilities.

The Olympus E-PL2 incorporates an 11-point contrast detection autofocus system supporting single and continuous AF modes alongside face detection and AF tracking functionalities. While lacking phase detection AF technology (common in higher-end models), its AF system demonstrates dependable accuracy and reasonable speed in good light, suitable for still subjects and moderate action photography. Face detection aids portrait shooters by prioritizing subject sharpness.

Conversely, the Pentax Efina is limited to contrast-detection AF with no continuous AF, no focus tracking, and limited subject recognition. Its focus speed is slower, reflecting point-and-shoot market positioning. The macro focusing distance minimum of 20 cm can assist close-ups but overall autofocus versatility is constrained.

For disciplines such as wildlife, sports, or street photography demanding rapid acquisition and sustained tracking, the Olympus system offers notable practical advantages.

Lens Ecosystem and Versatility

Lens options and compatibility directly affect a system’s long-term usability and creative potential.

The Olympus E-PL2, built on the Micro Four Thirds (MFT) mount, accesses over 100 lenses - including Olympus, Panasonic, and third-party options - spanning wide-angle, telephoto, macro, and speciality glass. The 2.1x crop factor influences focal length equivalency but delivers excellent balance between reach and compactness. Lens stabilization may supplement the in-body image stabilization.

By contrast, the Pentax Efina features a fixed 26–130mm equiv. zoom lens with a relatively slow aperture range of f/3.5–6.3. This built-in zoom covers moderate focal lengths but lacks the flexibility and optical quality control of interchangeable lenses.

Photographers requiring system expandability or specialized lenses (macro, tilt-shift, ultra-fast primes) will find the Olympus platform vastly superior. The Efina suits users content with a simple, all-in-one solution.

Shooting Modes and Exposure Control

Sophisticated exposure options and shooting modes broaden creative scope and precision.

The E-PL2 supports full manual, aperture priority, shutter priority, and program exposure modes, alongside exposure compensation and custom white balance. Its traditional controls facilitate rapid mode switching and exposure tweaking, key for advanced shooting scenarios like landscape bracketing or artistic portraiture requiring precise depth of field or motion control.

The Efina lacks manual exposure modes, exposure compensation, and priority modes entirely. It operates fully in auto or scene mode, limiting photographers to basic snapshots without intentional exposure experimentation.

Hence, enthusiasts and professionals will gravitate to the Olympus for its comprehensive exposure control suite.

Burst Shooting and Continuous Performance

Evaluating the ability to capture fast moving subjects requires analysis of frame rates and buffer performance.

The Olympus E-PL2 delivers a respectable 3 fps continuous shooting rate with autofocus tracking, suitable for casual sports and wildlife photography. While this rate may be insufficient for fast action professionals, it still allows capture of critical moments with some flexibility.

The Pentax Efina does not specify continuous burst capabilities and defaults to single shot operation, insufficient for dynamic subject tracking.

Therefore, the Olympus E-PL2 holds a clear advantage in documenting sports, wildlife, or events requiring burst capture.

Image Stabilization and Low Light Handling

Stabilization and noise control shape handheld shooting feasibility and image sharpness in challenging conditions.

The E-PL2 incorporates sensor-based image stabilization (IBIS), which compensates for shake regardless of lens used, supporting sharper images at slower shutter speeds - a boon for low light and telephoto shots.

The Efina employs digital image stabilization, which approximates shake compensation by cropping and post-processing, often degrading image resolution and quality. Its maximum ISO of 1600 limits low light capability, while Olympus extends native ISO to 6400, with cleaner noise profiles supported by the CMOS sensor.

For nighttime, indoor, or astro photography, Olympus offers meaningful advantages in usable shutter speeds, image clarity, and noise performance.
