Olympus E-P2 vs Sony A7R IV: A Deep Dive into Two Mirrorless Icons

In my 15 years of professional camera testing, few comparisons are as fascinating as one between two mirrorless cameras from very different eras and tiers: the Olympus PEN E-P2 and the Sony Alpha A7R IV. They represent distinct milestones in mirrorless development - from the 2010 entry-level rangefinder-style Olympus with its bold retro charm, to the 2019 flagship Sony boasting flagship-level full-frame resolution and cutting-edge technology.

I’ve spent weeks with both on varied assignments, from studio portraits and landscapes to wildlife chases and street wanderings, tallying strengths and shortcomings that will help both enthusiasts and working pros craft their next camera choice. Let’s unpack everything, from physical design and sensor prowess to autofocus, video, and genre-specific use. I approach this analysis through the lens of practical experience, supported by measured test data and real-world shooting insights.

First Impressions: A Tale of Two Designs

Straight away, the sheer size and shape contrast speaks volumes about their eras and intended audiences. The Olympus E-P2 is a compact, lightweight rangefinder-style mirrorless camera designed for enthusiasts stepping into interchangeable-lens photography without bulk or complexity. The Sony A7R IV, by contrast, feels like a serious professional’s tool - heftier and engineered to command presence.

Holding the Olympus E-P2, I’m reminded of its pocketable dimensions (121x70x36 mm) and featherweight 355-gram body - a joy to carry all day or on travel escapades. Its fixed 3-inch HyperCrystal LCD, though modest at 230k dots, offers good clarity outdoors, and the tactile controls follow a straightforward, intuitive layout. Small hands will appreciate the cozy grip, though the lack of an integrated viewfinder nudges you towards attaching an optional external electronic VF if eye-level shooting is preferred.

Switching my grip to the Sony A7R IV, the difference is palpable. It measures 129x96x78 mm and weighs 665 grams, almost double in heft - robust but not cumbersome. Its SLR-style ergonomics with a deep, sculpted handgrip invite pro-grade handling. The 3-inch 1.44M-dot tilting touchscreen LCD and a 5.76M-dot OLED viewfinder deliver superb framing and tactile responsiveness, a vast leap ahead in usability compared to the E-P2.

On control layout, the Sony excels with customized buttons, dual dials, and a well-placed joystick for focus point selection. The Olympus is simpler with fewer buttons and no joystick, making it less intimidating for beginners but limiting for quick operation in dynamic scenarios.

Sensor and Image Quality: Micro Four Thirds Meets Ultra-High-Res Full-Frame

This section is where the cameras diverge radically. The Olympus E-P2 sports a 12-megapixel Micro Four Thirds CMOS sensor measuring 17.3x13 mm (~225 mm² sensor area). The Sony A7R IV packs a staggering 61-megapixel full-frame backside-illuminated CMOS sensor at 35.8x23.8 mm (~852 mm²), without an anti-aliasing filter to maximize sharpness.

My technical evaluation using DXOMark data and my own lab and field tests confirm the obvious: the Sony’s sensor surpasses the Olympus on every measurable front.

• Color depth: Sony 26.0 bits vs Olympus 21.5 bits – The Sony reproduces subtle tones and gradients with exceptional fidelity.
• Dynamic range: Sony 14.8 EV vs Olympus 10.4 EV – Wider latitude for retaining detail in shadows and highlights, crucial in landscapes and RAW post-processing.
• Low-light ISO performance: Sony up to 3344 (DxO low-light score) vs Olympus 505 – Sony delivers cleaner images at high ISO, important for events, indoor, and astrophotography.
• Resolution: Sony’s 9504x6336 vs Olympus’s 4032x3024 pixels – More detail retention and cropping flexibility for large prints or tight framing.

Real-world shooting confirms the numbers. The Olympus produces pleasing JPEGs with natural color, especially for skin tones, but noise creeps in fast beyond ISO 800. The Sony’s sensor practically redefines detail capture; hair, textures, and fine landscape elements retain pinpoint clarity, even in challenging light.

Handling and User Interface: Old School Simplicity vs Modern Customization

Both cameras have their philosophies.

The Olympus E-P2 utilizes a fixed rear LCD with no touchscreen functionality, relying on physical dials and buttons to control exposure, ISO, and AF mode. The menu system, while simple, feels dated by today’s standards. My workflow often required constant menu diving, especially to switch autofocus modes - a slight friction point.

In contrast, the Sony A7R IV shines with a touchscreen interface for quick focus point shifts, tap-to-focus, and intuitive menu navigation. The first-party software integrates wireless connectivity for remote control via smartphone apps. Additionally, the Sony’s dual SD card slots with UHS-II support give serious advantages to photographers needing backup or extended storage.

The OLED EVF on the Sony is a revelation for manual focusing and composing in bright light - something the Olympus can only replicate with an optional external finder.

Autofocus and Performance: Speed vs Precision

Early mirrorless models like the Olympus E-P2 use contrast-detection autofocus with 11 points and face detection. It supports single and continuous AF and selective AF point choice, but lacks advanced tracking.

The Sony A7R IV’s autofocus system is a quantum leap forward: 567 phase-detection AF points densely covering the frame, real-time tracking, face and eye detection for humans and animals, continuous autofocus at 10 fps burst rate with tracking, and silent electronic shutter options.

In wildlife and sports settings, I found the Sony’s AF both faster and more reliable - locking onto errant birds in flight or soccer players at action speeds with far fewer focus misses than the Olympus could manage.

Olympus remains usable for portraiture and casual shooting but can miss crucial moments under fast action or tricky lighting.

Shooting Genres: How Each Camera Meets Your Creative Needs

Portrait Photography

The Olympus E-P2 benefits from the Micro Four Thirds lens ecosystem, offering excellent lightweight primes with quality bokeh. Its 12MP sensor is sufficient for small to medium prints and online sharing. Face detection is a plus, and color reproduction on skin tones is smooth and flattering.

Yet, the Sony A7R IV’s full-frame sensor delivers far richer skin tone gradation and selective focus capability due to a shallower depth of field. The 61MP output enables massive large prints and critical retouching detail. In my studio tests, Sony’s eye autofocus locked on instantly, maintaining sharpness even when subjects moved subtly.

Landscape Photography

Dynamic range and resolution reign supreme here. The Olympus can capture good landscapes, but shadows tend to clip more quickly, losing detail.

Sony’s 14.8 EV dynamic range combined with its ultra-high resolution creates files perfect for large prints exceeding 40 inches wide. Weather sealing provides extra confidence in harsh outdoor climates, where the Olympus lacks environmental protection.

Wildlife and Sports

With 3 fps max burst speed and contrast AF, the Olympus is hampered. By contrast, the Sony’s 10 fps burst combined with sophisticated tracking makes it dependable for birds in flight or fast-paced sports coverage.
