In summary: The E-M5 offers superior ergonomics and control for enthusiasts/pros requiring tactile feedback and customization, whereas the WX1 prioritizes portability and simplicity for snapshot takers.

Sensor and Image Quality: Size Matters

At the heart of any camera lies its imaging sensor, which substantially influences image quality, low light performance, and creative possibilities.

The Olympus OM-D E-M5 features a 16MP Four Thirds-sized CMOS sensor (17.3 x 13 mm, 224.9 mm² area), a traditional size within the Micro Four Thirds system enabling a balanced trade-off between compactness and image quality. The E-M5’s sensor implements a native anti-aliasing filter and utilizes Olympus’s TruePic VI image processor, boosting dynamic range and color depth.

In contrast, the Sony WX1 contains a considerably smaller 1/2.4" back-illuminated CMOS sensor (6.1 x 4.6 mm, 27.9 mm² area) with 10MP resolution. While back-illuminated design helps in gathering light more efficiently, the sensor size is dramatically smaller - roughly one-eighth the area of E-M5’s sensor - which restricts image quality, especially in noise performance and dynamic range. The WX1 relies on Sony’s Bionz processing engine typical of compact cameras.

Image Quality Metrics

• Resolution: E-M5’s 16MP sensor produces images up to 4608 x 3456 pixels, allowing for larger prints and cropping flexibility, whereas WX1 outputs 3648 x 2736 (10MP), sufficient for casual prints and screen use but limiting for professional crops.

• Dynamic Range: Olympus’s sensor delivers a robust dynamic range of 12.3 stops (DxOMark tested), preserving details in shadows and highlights - critical for landscapes and high-contrast scenes. The WX1 sensor provides far less DR, resulting in blown highlights and crushed shadows in challenging lighting.

• Low-Light Performance: The E-M5 offers a usable ISO range from 200 up to 25,600 native (ISO 100 as a minimum boosted ISO), with a low-light score equivalent to ISO 826, suitable for indoor and dim scenes with manageable noise levels. The WX1 tops out at ISO 3200 but with pronounced noise beyond ISO 400 due to limited pixel pitch and sensor size.

• Color Depth: Olympus’s 22.8 bits color depth surpasses the WX1’s untested specific metric but expected to be lower given sensor size.

Practically speaking, the E-M5 delivers far superior image quality, especially when shooting RAW (supported). The WX1, a JPEG-only compact, suffices for casual image needs and social media but falls short under professional or critical use.

Autofocus Systems and Performance: Speed, Accuracy, and Reliability

Autofocus technology is often a decisive factor for users capturing fast-moving subjects or precise portraits.

• The Olympus E-M5 employs a contrast-detection AF system with 35 focus points and face detection capabilities. While lacking hybrid phase-detect focus common in modern mirrorless cameras, it offers continuous AF for tracking (albeit slower than newer designs) and touch-to-focus on its screen. It supports single AF, continuous AF, and selective area mode. Overall, focus accuracy and speed are competent for most types of photography but can lag in fast-action scenarios.

• Conversely, the Sony WX1 is equipped with a simpler 9-point contrast-only AF, center-weighted, lacking face detection or tracking. It only supports single AF and no continuous AF, which means its focusing is slower and less precise, especially on moving subjects, compromising use in dynamic environments.

In sports or wildlife photography - where fast and reliable autofocus tracking is critical - the E-M5 remains usable within 2012-era constraints but would struggle compared to modern systems. The WX1 is best suited for static subjects or casual snapshots.

Build Quality and Weather Resistance

Professional and enthusiast photographers demand cameras that endure diverse environments.

The E-M5 stands out with extensive environmental sealing (dust and splash proof), magnesium alloy chassis, and ergonomic robustness. While not fully waterproof or shockproof like some action cameras, it tolerates challenging outdoor conditions where moisture or dust exposure is common.

The Sony WX1 offers no weather sealing, uses plastic construction, and is vulnerable to environmental damage. This substantially limits its potential for rugged use or extended outdoor travel.

Thus, for photographers frequently shooting landscapes, wildlife, or traveling in varied climates, the E-M5 provides trustworthy reliability over the WX1.

Versatile LCD and Electronic Viewfinder Interfaces

A well-designed user interface enhances ease of use, composition, and reviewing images in diverse lighting.

The Olympus OM-D E-M5 features a 3-inch tilting touchscreen OLED display with 610k-dot resolution, which makes composing from low or high angles easier. The touchscreen supports focusing and menu navigation - uncommon for cameras of that generation - and delivers bright, high-contrast images for previewing. The OLED technology also aids power efficiency and dynamic color representation.

Further, the E-M5 has a built-in electronic viewfinder (EVF) boasting 1.44M dots resolution, offering 100% coverage and 0.58x magnification. This EVF provides precise framing and focus confirmation, especially beneficial in bright sunlight where LCDs may wash out.

By contrast, the Sony WX1 has a smaller fixed 2.7-inch LCD with 230k-dot resolution and no touchscreen or EVF, making viewing in direct sunlight difficult and composition less flexible.

For photographers relying heavily on manual focus or framing accuracy, the Olympus’s EVF and tilting LCD combination is a major usability advantage.

Lens Ecosystem and Compatibility: Flexibility for Advanced Vision

Lens availability directly influences creative possibilities.

• The Olympus E-M5 utilizes the Micro Four Thirds mount, sharing compatibility with a vast ecosystem comprising over 100 lenses from Olympus, Panasonic, and third parties, spanning primes, zooms, macro, ultra-wide, and telephoto optics. This flexibility means photographers can build a system optimized for portraits, landscapes, wildlife telephoto reach, or macro work.

• The Sony WX1 features a fixed Leica-branded zoom lens (24-120mm equivalent, f/2.4-5.9), with modest 5x optical zoom. While convenient for casual use, it severely limits creative control, particularly for shallow depth-of-field portraits or specialized macro photography.

In practice, the Olympus E-M5 appeals to enthusiasts intent on expanding system capabilities over time, while the WX1 satisfies users who want an all-in-one solution without changing lenses.

Battery Life and Storage: Practical Shooting Endurance

Shooting duration and memory support impact usability in the field.

The Olympus E-M5 uses proprietary BLN-1 batteries, rated for about 360 shots per charge, which is average among mirrorless cameras of its time and improved further with power-saving modes. It supports SD/SDHC/SDXC cards via a single slot, providing ample storage flexibility.

In contrast, the Sony WX1’s official battery life rating is unspecified, but compact cameras of this class generally offer around 200–300 shots per battery charge. It accepts Memory Stick Duo/Pro Duo cards with single slot support.

While neither camera excels in battery endurance compared to DSLRs or newer mirrorless models, the E-M5 benefits from interchangeable batteries and prosumer-grade performance.
