Olympus E-M1 II vs Pentax WG-1: An In-Depth Hands-On Camera Comparison

When I first sat down to compare the Olympus OM-D E-M1 Mark II and the Pentax Optio WG-1, I knew I was looking at two radically different beasts - each designed with distinct photographers and priorities in mind. My approach was to rigorously evaluate these cameras head-to-head across a broad range of photographic genres and real-world scenarios, supported by thorough technical testing and years of direct experience with similar models.

This isn’t just a specs showdown. It’s about how each camera performs day-to-day: image quality nuances, autofocus reliability, ergonomics, durability, and creative flexibility. By digging below the surface, I want to help you decide which one aligns best with your style, demands, and budget.

First Impressions: Size, Build, and Handling

If you’re like me, the first thing you notice is the size and weight in your hands - that tactile feeling sets the tone for how a camera fits your photography life.

The Olympus E-M1 II sports a robust, SLR-style mirrorless body that feels rock-solid and substantial in palm. Weighing in at 574 grams with dimensions of 134x91x67mm, it’s built to be a reliable handheld companion during long shoots. Its magnesium alloy chassis is well-sealed against weather - dust, moisture, and mild inclement conditions. The grip is sculpted and comfortable for extended use, with obvious ergonomic thought behind control placement.

In stark contrast, the Pentax WG-1 is a compact tough camera. At only 157 grams and physically smaller (114x58x28mm), this camera is designed to go anywhere - underwater, hiking in rain, or tossed carelessly in a backpack. Its rugged environmental sealing includes waterproofing, dustproofing, shockproofing, crushproofing, and freezeproofing - a true adventure camera.

While the E-M1 II’s heft conveys professional quality, the WG-1’s compact form factor screams portability and durability. Your choice boils down to where you expect to take your camera.

Top Controls and User Interface: Intuitive Design vs Simplicity

Diving deeper into usability, no detail is too small. How controls are laid out affects your shooting flow profoundly.

Olympus’s layout on the E-M1 II showcases a professional’s kit: multiple dials for shutter speed, aperture, ISO, exposure compensation - all accessible without leaving your shooting position. Buttons are customizable, though none are backlit, which is a minor quibble in low-light.

Pentax’s WG-1 goes minimalist with very few manual controls. This is expected for a compact point-and-shoot: a mode dial, shutter release, zoom toggle, and a basic menu button. It lacks advanced exposure modes entirely, instead relying mostly on presets and full-auto modes. Its touchscreen is absent, which some photographers may find limiting.

If you’re after granular manual control and quick physical access to settings - essential in professional or creative scenarios - Olympus is your clear winner. For casual shooters prioritizing simplicity and ruggedness, the WG-1’s interface suffices without complexity.

Sensor and Image Quality: Micro Four Thirds Power vs Compact CMOS

The sensor is the heart of any camera, so I devoted ample time comparing the imaging engines and output quality.

The E-M1 II features a 20MP Four Thirds sensor (17.4x13 mm), paired with Olympus’s TruePic VIII processor. While smaller than full-frame, this sensor size strikes a well-tested balance, able to deliver sharp images rich in detail, excellent color depth (DxO color depth score 23.7 bits), and a dynamic range of 12.8 stops. Its native ISO range from 200 to 25600 provides commendable low-light performance, with usable results up to ISO 3200 or even 6400 depending on shooting conditions.

In contrast, the WG-1 houses a 14MP 1/2.3" CCD sensor - significantly smaller (6.17x4.55 mm). This translates to more noise under low light, limited dynamic range, and lower color fidelity compared to mirrorless or DSLR-grade sensors. Its ISO maxes out at 6400 but with much higher noise. Additionally, the CCD sensor technology is from an earlier generation and generally less capable for quality at higher ISO than modern CMOS sensors.

In practical shooting tests, the E-M1 II renders much cleaner images, finer textures, and richer tonal transitions. The WG-1’s images can be channeling a bit of compact camera softness and grain, especially indoors or at twilight.

LCD and Viewfinders: Composing Your Shots

Composing your images fluidly matters, so I explored the viewfinder and screen usability carefully.

The Olympus E-M1 II boasts a 3-inch fully articulating touchscreen LCD with 1037k-dot resolution - perfect for challenging angles and intuitive setting changes. Its OLED electronic viewfinder provides a detailed 2.36 million dot resolution with 100% frame coverage and 0.74x magnification, delivering a bright and accurate real-time preview even in sunny outdoor conditions.

The Pentax WG-1 has a 2.7-inch fixed TFT LCD with 230k dots resolution - markedly lower pixel density and no touchscreen functionality. It lacks any viewfinder, forcing framing through the LCD, which can be tough in bright sunlight or fast-moving environments.

From personal experience, for prolonged or professional shooting, Olympus’s superior viewfinder and articulating screen enhance accuracy, speed, and creative framing - especially useful for video or unusual angles.

Autofocus Systems: Tracking Speed and Accuracy

A camera’s ability to keep focus can make or break moments, especially when shooting wildlife, sports, or street photography.

The E-M1 II’s autofocus is a technological highlight. It features 121 hybrid focus points combining phase-detection and contrast detection with face and eye detection - though notably, it lacks animal eye autofocus which newer models have added. In real-world shooting, the autofocus locks swiftly and tracks moving subjects with very high accuracy, even in lower light or busy scenes. Sports and wildlife bursts at 60fps electronic shutter mode make this camera a formidable action tool.

The WG-1’s contrast-detection autofocus system is basic with only 9 focus points and no continuous autofocus modes. It is suitable for static scenes and casual snapshots but struggles during fast action or in dim environments. Its macro focusing starting at 1 cm is a nice feature for close-ups, but beyond that, it can’t keep pace with fast-moving subjects.

I ran comparative tests photographing birds in flight and urban runners. The Olympus kept crisp focus and minimal hunting, whereas the Pentax lagged or missed focus more frequently.

Shutter and Burst Performance: Freezing the Moment

High-speed shooting capabilities factor heavily for sports, wildlife, and street photographers.

The Olympus OM-D E-M1 II shines with blazing fast 60fps burst shooting using a silent electronic shutter - a feature I exploited to capture soccer games and bird flocks mid-flight. The mechanical shutter maxes out at 1/8000s, while the electronic shutter extends to 1/32000s, ideal for bright conditions and freezing fast action.

The Pentax WG-1 maxes out with a sluggish 1fps burst rate and the slowest shutter speed tops at 1/1500s. This makes it unsuitable for fast sequences or capturing motion with precision.

In practice, for any high-intensity action, Olympus’s burst and shutter speed capabilities dominate.

Weather Sealing and Durability: Ready for Elements or Adventure?

Environmental resistance can be critical depending on your shooting style.

The Olympus E-M1 II is weather-sealed extensively but not waterproof. It resists rain, dust, and moderate abuse, fitting for outdoor photography in challenging conditions - landscapes, travel, or event coverage.

In comparison, the Pentax WG-1 is a rugged marvel: waterproof up to 10 meters, shockproof, crushproof, freezeproof, and fully dust-sealed. It’s designed to survive and shoot underwater and in extreme environments where the Olympus would risk damage.

Therefore, the WG-1 excels as an adventure or travel companion for unpredictable and harsh situations, while the E-M1 II suits more traditional demanding professional environments with weather protection.

Battery Life and Storage Convenience

From my tests, battery longevity and storage are often overlooked but crucial factors in workflow and convenience.

The Olympus’s BLH-1 battery delivers around 350 shots per charge under typical conditions, with dual SD card slots providing flexible workflow options such as overflow or backup. USB 3.0 connectivity and HDMI add to its professionalism.

The Pentax WG-1 camera has a rated 260 shots per charge on the D-LI92 battery, with a single SD card slot plus internal memory. USB 2.0 is provided for modest transfer speeds. Wireless connectivity is limited to Eye-Fi card compatibility - now somewhat dated.

You’ll quickly notice the Olympus holds power and storage advantages crucial for longer shoots and heavy use.

Video Capabilities: 4K and Professional Audio Support

Video recording is integral today; let's dissect how these two fare.

Olympus E-M1 II offers UHD 4K recording at 24p (4096x2160 at 237 Mbps) and 30p (3840x2160), using H.264 codec with Linear PCM audio. It has a microphone and headphone jack, allowing for nuanced audio monitoring and external mics. Body stabilization assists smooth handheld filming.

Conversely, Pentax WG-1 maxes out at 1280x720 30fps with Motion JPEG format, lacks external mic input or headphone jack, with no in-body stabilization.

For videographers or hybrid shooters, Olympus is clearly more capable and flexible. The WG-1 is a simple point-and-shoot video option for casual clips.

Lens Ecosystem and Mount Compatibility

Olympus’s Micro Four Thirds mount boasts over 100 native lenses from Olympus and third-party manufacturers - from ultra-sharp primes to super-telephotos and fast zooms. This extensive system enhances creative possibilities for portraits, macro, sports, and landscapes.

The Pentax WG-1 has a fixed 28-140mm equivalent zoom lens with no option for lenses or accessories. This limits versatility but simplifies casual shooting.
