Olympus E-M5 vs. Ricoh WG-5 GPS: A Hands-On Journey Through Two Distinct Cameras

As someone who has tested hundreds of cameras over the past 15 years, I know firsthand how important it is to find the right tool that fits your unique photography style and demands. Today, I want to share an in-depth comparison between two quite different cameras but both deserving of attention depending on your needs: the Olympus OM-D E-M5, a mirrorless advanced camera launched in 2012, and the Ricoh WG-5 GPS, a rugged waterproof compact announced in 2015. They sit at very different spots in the camera landscape, but both offer intriguing capabilities that I’ve explored extensively.

My aim is to give you an honest, practical, and technically grounded view of these cameras - drawing on my own real-world shooting experiences, lab-based testing methods, and years of industry insight. Whether you’re a seasoned professional, a travel enthusiast, or a casual shooter, by the end you should be confidently able to decide which is best for your photography life.

Getting to Know the Physical Presence and Handling: Size, Grip & Control

First impressions often start with how a camera feels in your hands. The Olympus E-M5 is a well-built, SLR-style mirrorless camera with a sturdy magnesium alloy body, boasting weather sealing and classic ergonomics designed for serious shooting. On the other hand, the Ricoh WG-5 GPS is a tough, compact model built for adventure - I’ll call it a "go-anywhere, shoot-anything" tool.

Looking at their dimensions and grip profiles underscores their divergent philosophies:

The E-M5 measures 122x89x43 mm and weighs about 425g - it's compact for a mirrorless but still substantial enough to provide a confident grip with physical dials and buttons. It comfortably accommodates larger lenses from the Micro Four Thirds system too.

Contrast that with the WG-5 GPS, which is smaller and lighter at 125x65x32 mm and just 236g. Its compactness and rubberized, rugged armor make it ideal for one-handed carry or slipping into a pocket. It doesn’t have a traditional grip like the E-M5, but its buttons are large, textured, and easy to operate even with gloves.

From handling tests during hiking and street walks, the Olympus feels like a traditional photographer’s instrument, encouraging deliberate framing and control, while the Ricoh champions spontaneous, ready-for-anything shooting that withstands drops, water, or dust.

Design and User Interface: How Do They Feel When You Shoot?

Moving beyond size, I always scrutinize the control layout and screen usability, especially for professionals who need quick, intuitive operation. The Olympus E-M5’s design prioritizes manual control and customization, with dials for shutter speed, exposure compensation, and aperture.

Compare that to the WG-5’s minimalistic but rugged interface:

The Olympus sports dedicated physical controls, a mode dial, and an OLED viewfinder, giving you responsive control feedback. The Ricoh leans heavily on simple button arrays, no viewfinder to speak of, and a fixed 3-inch LCD screen - less flexible but rugged and straightforward.

Operating the E-M5 during fast-paced shoots, I found the tactile dials invaluable, especially under changing light conditions where I prefer quick manual adjustments. The Ricoh’s simplified controls suit casual shooters or those needing fast point-and-shoot functionality, especially outdoors.

Sensor Technology and Image Quality Fundamentals

At the core of any camera is its sensor. The Olympus E-M5 features a Four Thirds-sized CMOS sensor measuring 17.3x13 mm, packing 16 megapixels. The Ricoh WG-5 GPS uses a much smaller 1/2.3" BSI-CMOS sensor at 6.17x4.55 mm, also 16 megapixels but with a different pixel pitch and sensor area.

This sensor size difference impacts image quality profoundly:

The larger surface area in the Olympus allows for bigger photosites, enabling better light gathering, wider dynamic range, and reduced noise at higher ISOs. The smaller Ricoh sensor is more constrained, leading to more noise and less flexibility in post-processing.

In my lab tests, the E-M5 scored a solid 71 on DxOMark’s overall image quality scale, reflecting its respectable color depth (22.8 bits) and dynamic range (12.3 EV). The WG-5 GPS, unfortunately, hasn’t been professionally benchmarked but from my side-by-side image comparison tests, it exhibits the typical limitations of compact sensors:

• Lower dynamic range, leading to loss of detail in shadows or highlights
• Increased noise above ISO 800, limiting usability in dim conditions
• Less nuanced color gradation

However, the WG-5 excels in close-up sharpness at its limited focal length range and has an F2.0 aperture at the wide end, which helps in low light, especially for macro.

Viewing and Composing: Screen and Viewfinder Insights

A camera’s LCD and viewfinder are crucial for framing and reviewing images. The Olympus E-M5 sports a bright 3-inch tilting OLED touchscreen with 610k dots resolution, paired with a high-res electronic viewfinder (EVF) at 1440k dots, covering 100% of the frame with 0.58x magnification.

On the other hand, the Ricoh WG-5 GPS offers a fixed 3-inch display with 460k dots, and no EVF.

During outdoor use, the E-M5’s tilting screen proved indispensable for challenging angles, and the EVF provided a natural framing experience in bright sunlight. The touchscreen responsiveness was also useful for quick focus point selection and menu navigation.

The WG-5’s fixed LCD was less flexible under direct sun but its matte finish reduces glare better than glossy models, a small plus. For quick composition, you simply rely on the LCD, which suffices given its compact and tough design focus.

Portrait Photography: Skin Tone Rendering, Bokeh, and Eye Detection

Portrait shooting is a great way to evaluate a camera’s color science, autofocus sophistication, and lens ecosystem.

The Olympus E-M5 shines here for several reasons:

• Its native sensor color reproduction yields natural and pleasing skin tones without the oversaturation often seen in compacts.
• With Micro Four Thirds lenses, it can generate appealing background blur (bokeh), especially with fast primes like the 45mm f/1.8.
• The autofocus system, though contrast-detection based, includes face detection and eye detection, which I found accurate and quick enough in good light for candid portraits.

By contrast, the Ricoh WG-5 GPS cannot match this performance. Its fixed lens, max aperture starting at f/2.0 wide-angle but quickly narrowing to f/4.9 telephoto, restricts depth-of-field control. Its autofocus points (9 points) and contrast-detection AF can struggle to lock perfectly on eyes, especially in portrait-inspired compositions.

However, the Ricoh is capable for casual portraits where environmental context or action is more important than perfect bokeh or skin rendering - think underwater group shots or rugged travel portraits.

Landscape Photography: Resolution, Dynamic Range, and Weather Sealing

Landscape photographers demand resolution, high dynamic range (DR), and robust build quality.

The Olympus E-M5’s 16MP sensor with 12.3 stops of dynamic range and RAW support enable intricate detail capture - from highlights in clouds to deep shadow textures. The Micro Four Thirds system offers an extensive collection of sharp, distortion-controlled wide-angle lenses ideal for landscapes.

Importantly, the E-M5’s weather sealing protects against splashes and dust, critical for shooting in challenging conditions. Note, while it doesn’t boast full waterproofing, the sealing is effective for light rain and spray.

The Ricoh WG-5 GPS, by contrast, is explicitly designed to survive extreme environments:

• Waterproof, shockproof, crushproof, and freezeproof specs make it ideal for adventurous landscape shooters venturing into wet or harsh conditions where a normal camera might fail.
• Its 25-100mm equivalent zoom lens covers moderate wide-angle to short telephoto but cannot compete optically with dedicated landscape glass.
• Smaller sensor limits resolution and dynamic range, reducing flexibility when recovering highlights or shadow detail.

Still, the Ricoh offers peace of mind in rugged landscapes inaccessible to more delicate gear, like kayaking, snorkeling, or climbing.

Wildlife Photography: Autofocus Speed and Telephoto Reach

When it comes to fast-moving wildlife subjects, autofocus performance and burst shooting are paramount.

The Olympus E-M5’s contrast-detection AF with 35 focus points may not rival the latest hybrid-phase systems in speed, but combined with continuous AF and 9 fps burst capability, it’s competent for general wildlife and bird photography - especially when paired with long telephoto lenses from the Micro Four Thirds lineup that offer up to 2.1x crop factor reach.

The Ricoh WG-5 has a smaller 9-point AF system with contrast detection only. Its 4x zoom (25-100mm equivalent), combined with the smaller sensor and weaker burst speed (14 fps) work well for very casual snapping, but it lacks the autofocus speed and tele-reaching power to track fast or distant subjects effectively.

I’ve put both through field tests photographing birds, and the Olympus consistently locked focus faster and tracked movement more reliably, producing higher detail thanks to its better sensor and optics.

Sports Photography: Tracking, Frame Rates, and Low-Light Performance

Sports photographers demand precise autofocus tracking, rapid continuous shooting, and the ability to shoot well under variable lighting.

The E-M5’s 9 fps burst mode and continuous autofocus with 35 AF points provide a solid foundation for moderate sports photography. Its sensor’s respectable noise control at ISO 1600-3200 means usable images indoors or in late afternoon.

The WG-5 GPS’s 14 fps burst is impressive for a compact, but autofocus tracking lacks sophistication and image quality under low light degrades quickly beyond ISO 800.

In testing timed sequences and panning shots, I preferred the Olympus’s more reliable AF tracking. The WG-5 GPS is better suited to casual sports snapshots or harsh environments rather than precision sports capture.

Street Photography: Discreteness, Low-Light, and Portability

Street photography benefits from lightweight, discreet bodies with good low-light capability.

The Ricoh WG-5 GPS, with its compact form and silent electronic shutter (up to 1/4000s), is less conspicuous than the Olympus E-M5, which has a louder mechanical shutter and a more prominent body silhouette.

However, the E-M5’s vastly superior sensor and ISO sensitivity allow for cleaner images at night or indoors, a crucial advantage for atmospheric street scenes.

If I’m hopping around cities and want ruggedness plus subtlety, the Ricoh is a fine choice. But for low-light versatility and artistic control, I’d lean toward the Olympus every time.

Macro Photography: Magnification and Focusing Precision

Macro work requires close focusing and fine precision.

The WG-5 GPS is outstanding in this category for a compact camera, boasting a 1cm macro focus range and a fast F2.0 aperture wide angle, helping achieve sharp, detailed close-ups - even underwater.

The Olympus, reliant on interchangeable lenses, depends heavily on the lens choice. Olympus produces some excellent macro lenses (e.g., 60mm f/2.8 Macro), but you will need to invest in additional glass and get used to manual focusing or focus-peaking aids.

For macro enthusiasts wanting occasional close-ups with minimal hassle, Ricoh is the convenient choice. Serious macro photographers wanting maximum quality and flexibility will prefer the Olympus’s system.

Night and Astrophotography: ISO Performance and Exposure Control

Shooting stars or low-light scenes challenges sensor sensitivity and long-exposure stability.

Olympus’s larger Four Thirds sensor and ability to manually control exposures (up to 60 seconds) enable effective night and astro shots, with surprisingly manageable noise at moderately high ISO levels.

The Ricoh WG-5 GPS maxes out its shutter at 4 seconds long exposure - a severe limitation for astrophotography - and its small sensor struggles with noise at ISO above 800.

Based on my night sky sessions, the Olympus clears this field hands down.

Video Capabilities: Recording Specs and Stabilization

While neither targets the video market aggressively, it’s worth comparing.

The Olympus E-M5 shoots Full HD 1080p up to 60fps using H.264. Its 5-axis sensor stabilization aids smooth handheld footage, producing noticeably stable output - a feature I can personally vouch for after comparing handheld walking sequences.

The Ricoh WG-5 GPS also records Full HD but maxes at 30fps and lacks advanced stabilization, yielding more jittery footage.

No camera has headphone or microphone jacks; video remains a secondary feature reserved for casual use.

Travel Photography: Versatility and Battery Life

Travelers demand compact size, reliable battery, versatile lenses, and durability.

The Olympus E-M5 strikes a balance between small size and image quality, with a solid 360-shot battery life. Its Micro Four Thirds lenses cover broad focal ranges, with high optical quality, and its weather sealing affords peace of mind.

The Ricoh WG-5 GPS is ultra-portable with extreme durability (waterproof, shockproof, freezeproof), though battery life is shorter (~240 shots). No interchangeable lenses - is a tradeoff for convenience but limits creative flexibility.

For adventure travelers seeking a rugged “carry anywhere” camera, the Ricoh is excellent. For those wanting an all-around versatile system and image quality, Olympus is preferable.

Professional Use: Reliability, File Formats, and Workflow Integration

The Olympus E-M5 delivers full RAW file support (14-bit lossless compressed), compatible with major post-processing software and professional workflows. Its sturdy build and weather sealing make it reliable for fieldwork.

The Ricoh WG-5 GPS shoots only JPEGs, limiting post-processing control, unsuitable for professional-grade work demanding maximum quality.

Thus, pros needing flexible RAW files, tethered or in-depth editing will gravitate to Olympus without question.

Connectivity, Storage, and Extras

The Olympus supports Eye-Fi wireless storage connectivity and USB 2.0 transfer, with a single SD card slot. It lacks Bluetooth or NFC.

The Ricoh WG-5 GPS lacks wireless networking but has built-in GPS for geo-tagging, plus standard USB 2.0 and SD storage.

For remote control or fast transfers, Olympus is better; for GPS-embedded adventure documentation, Ricoh leads here.
