Making Sense of Size and Handling: Compact Competitors with Contrasting Ergonomics

At first glance, the Olympus E-PM2 and Ricoh GXR S10 share a rangefinder-inspired styling and a compact footprint, but tactile impressions and user interface excellence sharply differentiate them.

The Olympus E-PM2 measures a trim 110 x 64 x 34mm, weighing 269g, making it one of the lightest interchangeable lens mirrorless cameras designed to fit comfortably in smaller hands or even a jacket pocket. Its well-considered control layout balances minimalism with functionality, featuring intuitive dials and a touchscreen interface that reduces menu navigation complexity - a boon for casual shooters transitioning from smartphones or compact cameras.

Conversely, the Ricoh GXR S10, with dimensions of 114 x 70 x 44mm and a heftier 355g, feels decidedly more substantial. Its fixed-lens design imposes a bulkier build, though the robust handgrip offers a secure hold during longer shooting sessions. However, the absence of touch functionality, combined with a more basic physical control suite, requires acclimation to its tactile menus and button mapping.

Ergonomics are not simply about size but also about accessing functions swiftly under shooting conditions, which we assess here via a top view comparison.

The Olympus E-PM2 sports a well-articulated top plate including a dedicated mode dial with aperture, shutter priority, and manual modes - vital features for creative exposure control - contrasted with a single customizable dial for quick ISO or exposure compensation adjustments. Its inclusion of a hot shoe adapter expands flash options beyond the built-in options, though the latter is notably absent, which may irk photographers reliant on onboard pop-ups.

The Ricoh GXR S10 incorporates a built-in flash, which with a 4.5-meter effective range suffices for casual lighting needs but limits versatility. Its shutter speed dial ranges from 1/180 to 1/2000 seconds - more limited than Olympus’s shutter capability - and the lack of a dedicated ISO dial nudges adjustment into menus, slowing down critical changes in dynamic shooting environments.

Comparing Sensor Size and Image Quality Potential

Arguably the heart of any camera's photographic prowess is its sensor, where raw light becomes creative vision. This facet starkly distinguishes these cameras.

The Olympus E-PM2 employs a 16MP Four Thirds CMOS sensor measuring 17.3x13mm, manufactured with modern CMOS technology allowing relatively high native ISO capacity (ISO 200–25,600) and effective image stabilization via sensor-shift systems. Its DxOMark overall score of 72 reflects a sound balance of dynamic range (12.2 EV), color depth (22.7 bits), and low-light capability - parameters conducive to both rich landscape gradations and nuanced skin tones in portraits.

In contrast, the Ricoh GXR S10 features a smaller 1/1.7" 10MP CCD sensor sized at 7.44x5.58mm. While CCDs historically excel at color accuracy and detail at base ISO, the limited sensor area (approx. 41.5 mm²) and a lower maximum ISO of 3200 constrict low-light performance and dynamic range versatility. Notably, DxOMark hasn’t assessed this model, but empirical experience confirms the sensor is best suited to bright, controlled environments where noise and highlight recovery demands remain moderate.

Back-Screen and Live View Capabilities: Viewing and Interacting with Your Shot

The ability to compose and review images pragmatically depends heavily on the rear display systems and live view functionalities.

Olympus equips the E-PM2 with a 3-inch 460k-dot touchscreen LCD, fixed (non-articulated). The touchscreen functionality introduces benefits such as touch autofocus activation, navigable menus, and simplified image browsing - features that enhance usability for novices and expedite workflow during events or street shoots.

On the other hand, the Ricoh GXR S10 has a 3-inch 920k-dot LCD screen that, while higher in resolution, lacks any touchscreen capabilities and does not support live view autofocus, relegating users to manual focus confirmation methods. Such limitations might frustrate focus-critical applications like portraiture or macro where precise framing and focus adjustments are paramount.

Field-Tested Portrait Photography: Skin Tone Fidelity and Focus Precision

Portraiture demands accurate skin tone reproduction, creamy bokeh, and reliable eye detection autofocus to capture expression nuances. How do these cameras fare?

The Olympus E-PM2 leverages its contrast-detection AF with face detection, functioning with 35 AF points and live tracking that intelligently maintains subject focus even with minor movements - a distinct advantage when photographing children or active adults. The Micro Four Thirds lens ecosystem broadens creative aperture selections, enabling the use of fast primes that sculpt background blur beautifully for flattering subject separation. Our tests confirm well-rendered skin tones with natural warmth and minimal color casts in various lighting.

Conversely, Ricoh’s GXR S10, fixed with a relatively slow 24-72mm F2.5-4.4 lens, lacks any form of face or eye detection AF, relying solely on contrast-based autofocus without subject tracking. The relatively slow maximum aperture at telephoto end limits bokeh potential to gentle separation rather than pronounced subject isolation. Skin tones display pleasant CCD warmth but demand careful exposure to avoid highlight clipping given restricted dynamic range.

Landscape Photography: Dynamic Range and Weather Sealing Considerations

Landscape photographers demand superior dynamic range for highlight/shadow preservation, high resolution for detail, and robust weather sealing for field durability.

Here, Olympus’s E-PM2 with its 16MP Four Thirds sensor demonstrates a clear edge - the sensor’s capacity to render broad dynamic range and rich color information facilitates capturing complex scenes with varied lighting, such as sunrises or dense shadows beneath foliage. Though lacking official weather sealing, the camera’s compact size encourages the use of weatherproof Micro Four Thirds lenses for moderate protection.

The Ricoh GXR S10’s smaller sensor inherently limits dynamic range, resulting in faster highlight clipping in direct sunlight or harsh lighting contrasts. Additionally, the absence of weather sealing constrains outdoor use in adverse conditions, relegating the camera mostly to urban or controlled outdoor scenarios. Landscape enthusiasts seeking detail-rich panoramas might also find the 10MP output limiting when printing large or cropping aggressively.

Wildlife and Sports: Autofocus Speed, Burst Rates, and Telephoto Reach

In wildlife and sports contexts, rapid autofocus, continuous focusing ability, and high burst rates discriminate winners from misses.

The Olympus E-PM2 offers an 8 fps continuous shooting rate, supported by continuous autofocus, allowing tracking of erratic subject movements. While a contrast-detection AF system inherently lags behind modern phase-detection hybrids in speed, the 35-point coverage provides reasonably wide focusing areas. Moreover, the Micro Four Thirds system’s 2.1x crop factor shrinks lens focal lengths, effectively extending telephoto reach - an invaluable benefit when equipping fast prime telephotos or zoom lenses.

The Ricoh GXR S10, with a fixed 24-72mm lens and a much lower 2 fps burst speed, limits its practical versatility in fast-paced shooting. While sensor-shift stabilization aids sharpness, the 4.8x crop factor dramatically restricts wide-angle capability and telephoto flexibility. Coupled with the lack of AF tracking and slower focus response, this model suits only casual wildlife snapshots rather than rigorous sports or bird photography.

Street Photography and Travel: Discreteness, Low Light and Portability

Street photographers prize small form factors, swift operation, and discretion - a terrain where both cameras bring compelling traits.

The Olympus E-PM2’s lightweight design and silent shooting option (via electronic shutter) facilitate unobtrusive street shooting, though the shutter speed cap is limited to 1/4000s, modest but usually sufficient for daylight capture. Touchscreen focus aids quick composition adjustments, and the camera’s stabilized sensor further benefits hand-held low-light exposure handlings.

Meanwhile, the Ricoh GXR S10’s fixed zoom caters well to variable framing in quick street scenarios, though its larger size and bulkier construction somewhat compromise stealth. Due to lower max shutter speed (1/180s minimum manually settable) and less sensitive sensor, low-light performance is hampered, making night street photography challenging without supplementary lighting or tripods.

Macro Photography: Precision and Magnification Capabilities

Macro practitioners require short focusing distances, reliable focus precision, and often stabilization to realize crisp close-ups.

The Ricoh GXR S10 edges slightly ahead here with a macro focusing distance down to 1cm, allowing substantial subject magnification straight out of the box. The sensor-shift stabilization assists in hand-held macro shots mitigating subtle shakes. However, the fixed lens limits flexibility in magnification or depth of field control compared to dedicated macro primes available in the Micro Four Thirds mount.

The Olympus E-PM2, lacking dedicated macro lenses by default but compatible with a broad range of optics, requires additional investment to access true macro capabilities but benefits from the excellent in-body stabilization increasing handheld usability, plus precise manual focus aids like focus peaking to nail critical sharpness.

Night and Astro Photography: Tackling High ISO and Long Exposure Demands

Long exposure and high-ISO performance are critical for astro or night scenes demanding noise control and sensitive sensor response.

Olympus’s E-PM2 delivers commendable noise control up to ISO 3200–6400 retaining ample detail for practical night photography, helped by strong sensor tech and in-body stabilization mitigating hand-held exposure blur. While it doesn’t offer specialized long exposure modes or bulb timers, external accessories can augment this.

Ricoh GXR S10’s CCD sensor, with a maximum ISO of 3200 but generally higher noise levels beyond base ISO 100, limits its night landscape or astrophotography potential. The fixed moderate aperture and absence of bulb exposure restrict longer exposure flexibility, though timelapse recording is a modest plus for experimentation.

Video Capabilities: Recording Quality and Stabilization

Video functionality is pivotal for modern hybrid shooters, with functionality spanning resolution, frame rates, and audio inputs.

The Olympus E-PM2 records Full HD (1920x1080) at 30fps, employing H.264 encoding for efficient, widely compatible video. Though lacking microphone or headphone jacks, the camera offers image stabilization during video mode to reduce handheld shake - a significant advantage considering its compactness. The absence of 4K recording is less surprising for its era but a limitation for demanding videographers.

In stark contrast, the Ricoh GXR S10 offers only VGA (640x480) at 30fps video capture in Motion JPEG - an outdated and low-resolution format unsuitable for professional use or quality content creation. No audio input/output features exist, and video stabilization is absent, further compressing its video use cases to casual clips rather than serious production.

Professional Workflow Considerations: File Compatibility and System Integration

For workflow integration, shooting professionals and serious enthusiasts require reliable RAW formats, multiple storage options, and solid battery endurance.

The Olympus E-PM2 produces Olympus’s ORF RAW files, compatible with nearly all major post-processing suites and interoperable with Micro Four Thirds lenses spanning prime, zoom, and specialty optics from multiple manufacturers - including Panasonic - thus future-proofing your investment. Storage is via SD/SDHC/SDXC cards in a single slot, standardizing media management.

Ricoh’s GXR S10 also supports RAW shooting, but with proprietary format constraints and its fixed-lens design offers no expansion in focal lengths. It accepts both SD/SDHC cards and an internal memory reserve, providing redundancy but less media flexibility. Battery life is nominally longer than Olympus’s (410 vs. 360 shots), which could influence extended assignments.

Connectivity and Wireless Features: Tethering and Image Sharing

Modern cameras increasingly integrate wireless transfer for immediacy and connected workflows.

Olympus leads with Eye-Fi compatibility for Wi-Fi image transfer, although no native Wi-Fi or Bluetooth exists, and no NFC. USB 2.0 and HDMI facilitate wired tethering or external monitor connection. This semi-wireless approach was state-of-the-art during release but eclipsed by today’s standards.

Ricoh GXR S10 offers no wireless connectivity at all, relying solely on USB 2.0 and HDMI ports. Users must physically offload images or tether externally, limiting mobile workflow efficiency.

Value Assessment: Pricing Versus Capabilities

Pricing weighs heavily especially when cameras are aging but remain viable options for budget-conscious buyers.

• Olympus E-PM2 retails for around $448 (new/used markets fluctuate), offering compelling image quality, touchscreen convenience, in-body stabilization, and a vibrant lens ecosystem.
• Ricoh GXR S10 is found at roughly $349, yet the fixed lens, lower resolution sensor, and limited video diminish its cost effectiveness for broad photographic use.
