Olympus OM-D E-M5 II vs Olympus PEN E-PL5: In-Depth Mirrorless Camera Comparison for Enthusiasts and Pros

In the evolving micro four thirds mirrorless space, Olympus has long stood as a pioneer, catering to both entry-level users and advanced photographers with a rich lens ecosystem and thoughtful ergonomics. Two cameras significant in Olympus's lineup - the Olympus OM-D E-M5 II, announced in early 2015, and the earlier Olympus PEN E-PL5 from 2012 - represent markedly different approaches and generations, yet both remain popular with certain user segments.

Drawing on over 15 years of experience testing hundreds of mirrorless cameras in diverse real-world conditions, this article offers a detailed, technical, and balanced evaluation of these cameras. We analyze their build, image quality, autofocus, and feature sets while exploring strengths and weaknesses across photography disciplines such as portrait, landscape, wildlife, and video, among others. By incorporating practical performance insights alongside industry benchmarks, we empower you to decide which Olympus fits your needs best.

Physicality and Handling: Classic vs Evolved Ergonomics

The Olympus OM-D E-M5 II brings a more sophisticated, professional-style SLR-type mirrorless body design compared to the more compact rangefinder-esque PEN E-PL5. Understanding how size, weight, and controls affect shooting comfort can be decisive, especially for long shooting sessions or travel.

• Dimensions & Weight: The E-M5 II measures 124 x 85 x 45 mm and weighs approximately 469 grams (excluding lens), whereas the E-PL5 is smaller at 111 x 64 x 38 mm and lighter at 325 grams. The increased bulk of the E-M5 II translates to a heftier feel but adds substance that many find stabilizing, particularly with larger lenses.

• Ergonomics: The E-M5 II features a pronounced grip with pronounced button placement designed for efficient operation without removing the eye from the viewfinder, while the E-PL5 maintains a minimalist profile suitable for casual shooting yet less intuitive for rapid settings changes.

• Build Quality & Weather Sealing: The OM-D E-M5 II offers extensive environmental sealing against dust and splash, not present in the E-PL5, ensuring better reliability in outdoor and demanding conditions.

Controlling complexity increases from the E-PL5 to the E-M5 II, reflecting the latter’s more advanced user base. Photographers accustomed to classic DSLR layouts will appreciate the deliberate button layout and tactile feedback of the E-M5 II’s interface. Let’s look more closely at the top layout.

• The top plate of the E-M5 II reveals dedicated dials for exposure compensation and mode selection, plus a multi-function control dial, none of which appear on the E-PL5. Such direct control facilitates quicker manual exposure adjustments and operational flow.

• Both cameras feature electronic viewfinders, but the E-M5 II’s EVF boasts a 2360k-dot resolution with 100% coverage and 0.74x magnification, surpassing the E-PL5, which lacks a built-in EVF and relies on optional add-ons, which impacts framing precision and usability especially in bright conditions.

• The E-M5 II also sports a fully articulated 3-inch touchscreen with 1037k-dot resolution, outclassing the E-PL5’s smaller tilting 3-inch screen at 460k dots.

The difference in rear-screen clarity and articulation greatly benefits users who shoot video or unusual angles.

Sensor and Image Quality: Technology Maturity Over Time

Both cameras employ a Four Thirds sensor measuring 17.3x13mm, with the same physical sensor area approximately 225mm². However, advancements in sensor technology and image-processing engines materially influence final image quality.

While nominally similar on paper, the E-M5 II's TruePic VII processor enables superior noise reduction algorithms, subtly superior dynamic range handling, and enhanced color reproduction accuracy, especially in challenging lighting conditions. This translates into cleaner high ISO images and better highlight retention during post-processing.

In practical testing with landscape and night photography, the E-M5 II produces images with richer tonality and less chroma noise above ISO 1600. The smaller improvement in dynamic range is nevertheless relevant for photographers who pull detail from shadows.

Autofocus System: Precision and Speed

Autofocus performance directly impacts usability, especially for fast-moving subjects or critical focus in portraiture.

Both rely on contrast-detection AF systems as neither incorporates phase-detection pixels on sensor, common in newer models.

The E-M5 II’s superior focusing engine and higher number of AF points deliver noticeably faster and more reliable autofocus acquisition and tracking in real-world tests - critical in wildlife, sports, and street photography where speed and precision under variable lighting directly affect keeper rates.

In slower 35-point AF systems like the E-PL5, autofocus hunting in low contrast scenes is more prevalent, making it less ideal for demanding genres.

Burst Shooting and Buffer Considerations

The E-M5 II’s 10 fps burst with mechanical shutter (and up to 1/16000s silent electronic shutter) offers versatility for capturing decisive moments during sports or wildlife action. The E-PL5 maxes at 8 fps but only with lower buffer depth, restricting burst duration.

Lens Mount and Ecosystem: Shared Foundation, Diverging Needs

Both utilize the Micro Four Thirds lens mount compatible with an exceptionally broad range of over 100 lenses - from ultra-wide to super-telephoto and specialized prime optics.

This shared mount affords flexibility, but the E-M5 II’s advanced features like focus bracketing and in-body 5-axis stabilization encourage demanding users to pursue stabilized telephoto and macro lenses more aggressively, with improved image quality owing to stable capture.

Image Stabilization: A Defining Feature Difference

One of the hallmark upgrades with the E-M5 II is its comprehensive sensor-based 5-axis image stabilization, which corrects yaw, pitch, roll, vertical, and horizontal shift movements.

In contrast, the E-PL5 offers basic in-body stabilization but lacks the advanced 5-axis correction.

In practical terms:

• The E-M5 II enables hand-held shooting at shutter speeds up to 4-5 stops slower than normal without decentered blur.
• Macro and telephoto shoot-out-of-hand benefit significantly, improving success rates in low light and nature photography.

Video Capabilities: Bridging Stills and Motion

Video has become a crucial feature for hybrid shooters.

The E-M5 II’s ability to record 1080p video at 60fps offers smoother video capture and slow-motion post-production flexibility absent on the E-PL5. It also includes a microphone jack for external audio - an important feature for serious video use. The advanced image stabilization further improves handheld video smoothness, critical for run-and-gun recording.

Battery Life and Storage

• E-M5 II uses BLN-1 battery offering approximately 310 shots per charge.
• E-PL5 uses BLS-5 with roughly 360 shots per charge.

While the E-PL5 has modestly longer rated battery life, our testing showed minimal difference in real-life usage, where factors like live view and video shorten actual frames per battery cycle.

Both use a single SD/SDHC/SDXC card slot, standard for mirrorless cameras of their era.

Connectivity and Wireless Features

• The E-M5 II incorporates built-in Wi-Fi for image transfer and remote control, a significant advantage for modern workflows.
• The E-PL5 relies on Eye-Fi card compatibility for wireless transfer, which is limited and outdated.

This difference marks a critical usability improvement for social media photographers or those wanting instant sharing.

Comprehensive Photo Sample Analysis

Real-world image samples reveal nuanced superiority of the E-M5 II in color fidelity and detail retention, particularly at high ISO settings and complex light situations such as sunsets or shaded forests. Both cameras deliver sharp 16MP detail at base ISO, but the improved processing and stabilization enable the E-M5 II to clinch more compelling portraits and landscapes.
