Olympus OM-D E-M5 II vs Ricoh GR: An In-Depth Camera Comparison for Enthusiasts and Professionals

In the quest for a new camera, enthusiasts and professional photographers frequently encounter two distinct categories that this comparison aims to explore comprehensively: the advanced mirrorless segment represented by the Olympus OM-D E-M5 II, and the large sensor compact class embodied by the Ricoh GR. Although both cameras share certain image quality aspirations, their design philosophies, feature sets, and intended use cases diverge significantly. Drawing on over fifteen years of hands-on experience testing thousands of cameras under diverse photographic disciplines, this article provides a rigorous, data-driven, and practice-oriented comparison of these two models, helping you make an informed decision tailored to your specific workflows and creative goals.

Physical Design and Handling: Ergonomics that Define Shooting Experience

Understanding the physical dimensions, weight, and control layout is foundational to assessing user comfort and operational efficiency during shooting sessions. The Olympus E-M5 II, as a mirrorless interchangeable lens camera (MILC) with a Micro Four Thirds mount, assumes a classic SLR-style mirrorless shape with substantial grip and button presence, whereas the Ricoh GR is designed as a large sensor compact camera emphasizing discreetness and portability.

Measured in millimeters, the Olympus E-M5 II's dimensions stand at approximately 124 x 85 x 45 mm, weighing 469 grams without a lens attached. This size comfortably accommodates a more extensive set of physical controls, multiple dials, and provides a robust grip - features appreciated during prolonged landscape or wildlife shoots where stable handling is vital. In comparison, the Ricoh GR’s compact form factor, measuring around 117 x 61 x 35 mm and weighing merely 245 grams, positions itself as one of the smallest APS-C sensor cameras on the market. This makes it highly pocketable, suitable for street photographers prioritizing discretion and agility.

Ergonomically, the Olympus offers numerous customizable physical controls, including dual command dials and an articulated touchscreen that facilitate speedy manual adjustments - an invaluable asset for photographers who prefer tactile feedback and immediate access without diving into menus. The Ricoh GR, while minimalist, retains a dedicated control ring around its fixed 28mm equivalent F2.8 lens for aperture control, but lacks touchscreen interactivity and extensive external buttons, relying more on menu navigation and fewer shortcuts.

This fundamental design divergence reflects the cameras’ distinct philosophies: Olympus prioritizes operational versatility and professional ergonomics, while Ricoh leans towards rapid, unobtrusive shooting with minimal setup.

Sensor Technology and Image Quality: Assessing the Heart of the Camera

Sensor performance remains the critical determinant of image quality, critical for photographers aiming at print, large crops, or demanding post-processing. The Olympus E-M5 II employs a 16MP Four Thirds-sized (17.3 x 13 mm) CMOS sensor (MOS type) paired with the TruePic VII processor, whereas the Ricoh GR features a larger APS-C (23.7 x 15.7 mm) CMOS sensor, also 16MP, but with no specifically disclosed processor generation.

The Ricoh’s larger sensor area of 372.09 mm² outpaces Olympus’s 224.90 mm² by roughly 65%, lending it a fundamental advantage in light-gathering capacity and dynamic range, which translates to superior noise control at elevated ISOs and finer tonal gradations. DxOMark benchmarking reinforces this: the Ricoh GR records an overall DxOMark score of 78, including a color depth of 23.6 bits and dynamic range rated at 13.5 EVs, while the Olympus E-M5 II scores 73 overall with color depth at 23.0 bits and a dynamic range of 12.4 EVs.

This difference manifests palpably in real-world shooting scenarios requiring high ISO sensitivity - night or astro photography, indoor casual portraits, or dimly-lit street scenes - where the Ricoh GR demonstrates better low-light noise characteristics (DxO low-light ISO: 972 vs. 896). The Olympus, while respectable, encounters more visible luminance noise above ISO 1600, limiting its usability in such conditions without resorting to noise reduction that can compromise detail.

The Olympus, though constrained by smaller sensor size, benefits from its renowned 5-axis in-body image stabilization (IBIS), compensating somewhat for its ISO performance by enabling sharp long exposures handheld (up to 4–5 stops benefit). This feature, absent in the Ricoh GR, is crucial for landscape and macro photographers who require image sharpness without higher ISOs.

Autofocus Systems: Precision and Speed Across Genres

Autofocus (AF) reliability and performance are critical for capturing decisive moments, especially in fast-action genres such as wildlife, sports, or street photography. Here, the Olympus E-M5 II excels with its 81-point contrast-detection AF system augmented by on-sensor phase detection pixels, while the Ricoh GR employs a more rudimentary contrast-detection system without phase-detection.

The Olympus system supports face and eye detection autofocus with continuous AF tracking, enabling reliable subject acquisition and retention even during movement. It provides selectable AF modes: single, continuous, and tracking modes - vital for sports or wildlife photographers tracking erratic subjects. Additionally, manual focus assist is enriched with focus peaking and magnification.

In contrast, the Ricoh GR, despite its capable APS-C sensor, lacks advanced continuous AF tracking or face detection, relying predominantly on contrast detection with fewer focus points and no eye detection. Its autofocus performance is competent for static subjects and street photography where subjects are central and relatively still, but it falls short for action-packed scenarios or dynamic wildlife scenes.

Hence, for photographers requiring highly responsive autofocus systems, especially for sports or fast-moving wildlife, the Olympus E-M5 II presents a more refined solution.

Viewfinder and LCD Interface: Composing with Confidence

Composing accurately in diverse lighting conditions and shooting angles shapes the user experience deeply. The Olympus E-M5 II is equipped with a high-resolution electronic viewfinder (EVF) featuring 100% coverage, 2,360k-dot resolution, and approximately 0.74x magnification, surpassing many peers in offering a crisp, real-time preview of exposure, white balance, and depth of field. Its fully articulating 3.0-inch touchscreen LCD with 1,037k-dot resolution further enhances flexibility for low or overhead shooting and enables touch-based focus-shift.

Conversely, the Ricoh GR offers a fixed 3.0-inch TFT LCD with 1,230k-dot resolution but lacks a built-in EVF. It optionally supports an external optical viewfinder, which is a more rudimentary device without exposure or focus information, thus less versatile in variable conditions.

The Ricoh’s fixed screen and absence of touchscreen can be a limitation for photographers who demand intuitive interface navigation or versatile angle composition. Olympus’s interface and articulating touchscreen provide a superior experience for diverse shoots including macro, video, and landscape photography.

Lens Ecosystem and Compatibility: Creative Versatility

The Olympus OM-D E-M5 II leverages the Micro Four Thirds system’s mature lens mount, granting access to over 107 native lenses ranging from ultra-wide angles to super-telephotos. This extensive lens ecosystem is a major advantage for professional applications, enabling tailored setups for portraiture (fast primes), wildlife (telephoto zooms), macro (dedicated close-up optics), and video work (cine-style zooms).

The Ricoh GR, a compact with a fixed 28mm equivalent F2.8 lens, is inherently limited in optical flexibility, offering no changeable lenses and fixed focal length. The 28mm angle serves well for street, travel, and environmental portraiture but lacks telephoto reach or wider ultra-wide-angle options, and presents compromises in tight spaces or specialized genres such as macro or wildlife.

Therefore, while the Ricoh GR excels as a portable, ready-to-use camera with high-quality fixed optics, the Olympus is unmatched for those who require system adaptability and lens interchangeability.

Burst Rates and Shooting Performance: Capturing the Decisive Moment

Continuous shooting speed and buffer capacity play decisive roles in sports, wildlife, and action photography. The Olympus E-M5 II achieves a 10 frames per second (fps) continuous shooting rate, which is highly competitive in its class, enabling photographers to capture rapid sequences with high fidelity (shutter speeds up to 1/8000s mechanical, and electronic shutter speeds up to 1/16000s for silent operation).

In contrast, the Ricoh GR offers a slower burst rate of 4 fps with limited continuous AF capabilities, constraining its use for fast-action sequences. This limitation reflects its design targeting candid, spontaneous street or travel photography rather than high-speed sports.

Environmental Durability and Build Quality

Weather sealing and rugged construction matter considerably for outdoor, travel, and landscape shooters frequently exposed to challenging conditions. The Olympus E-M5 II provides robust environmental sealing against dust and splash water but does not claim full waterproof or freezeproof status. Its magnesium alloy body offers durability without excessive weight.

The Ricoh GR, while well built with a solid metal chassis, lacks weather sealing, relegating it to fair-weather or indoor environments primarily.

Video Capabilities: Meeting Hybrid Demands

For multimedia content creators and hybrid shooters, video specifications are critical. The Olympus E-M5 II supports Full HD 1080p video recording at up to 60p with advanced in-body 5-axis stabilization that smooths handheld footage effectively. It also includes a microphone input for improved audio capture, enhancing production quality for professional video work.

The Ricoh GR offers Full HD video up to 30p, limited by its lack of stabilization and absence of external microphone support, curtailing its utility for more serious videographers.

Battery Life and Connectivity

Battery endurance is often undervalued until field use reveals its impact on shooting duration. The Olympus E-M5 II delivers approximately 310 shots per CIPA standards, aided by efficient processor design, while the Ricoh GR offers about 290 shots, marginally lower but still competitive.

Connectivity wise, the Olympus features built-in Wi-Fi for image transfer and remote control; the Ricoh GR supports the Eye-Fi protocol, facilitating wireless image transfer but lacks onboard Wi-Fi or Bluetooth, reducing modern wireless workflow fluidity.
