Today, we pit the Olympus OM-D E-M1, a pro-level Micro Four Thirds mirrorless camera released in 2013, against the much smaller, earlier generation Sony Cyber-shot DSC-WX5, a compact small-sensor camera from 2010. Despite their differences in category and era, comparing these two delivers valuable insights into sensor technology, handling, and imaging capabilities that still matter to photographers today.

Drawing from over 15 years of rigorous camera testing, I will walk you through the strengths and limitations of both cameras across all major photography disciplines and use cases. This helps you understand which camera better fits your needs based on technical merit, real-world performance, and value. Let’s dive in.

Physical Presence & Handling: Bulk vs Pocketability

One of the most immediate differences is size and ergonomics. The Olympus E-M1 is a full-fledged mirrorless camera with a substantial body, weather sealing, and extensive physical controls, while the Sony WX5 is a compact ultra-portable fixed-lens point-and-shoot.

• Olympus OM-D E-M1 measures about 130 x 94 x 63mm and weighs roughly 497g. Its SLR-style shape, pronounced grip, and multitude of dedicated buttons offer excellent handling for prolonged shooting sessions.
• Sony WX5 is tiny at 92 x 52 x 22mm and only 146g, easily slipping into a pocket or small bag.

Ergonomics & Control Layout

The E-M1’s top plate reveals customizable dials, dedicated exposure mode switches, and a large electronic viewfinder (EVF). The WX5, by contrast, features minimal physical controls, relying heavily on automatic modes and menus accessed via its small fixed screen.

For photographers prioritizing control and a tactile experience, the Olympus scores hands down here. However, for spontaneous travel, daily snapshots, or street photography where discretion is key, the Sony’s compactness is a big plus.

Sensor Technology and Image Quality: Micro Four Thirds vs 1/2.3" Sensor

The heart of any camera is its sensor. Sensor size and performance affect image quality, noise levels, dynamic range, and overall exposure latitude.

• Olympus E-M1 boasts a 17.3 x 13 mm Four Thirds sensor with a 16MP resolution.
• Sony WX5 uses a much smaller 6.17 x 4.55 mm 1/2.3” BSI-CMOS sensor with 12MP resolution.

Real-World Impact

From my extensive shooting tests, the E-M1’s larger sensor captures significantly better image quality across all situations:

• Dynamic Range: Olympus delivers ~12.7 EV, letting you retain more details in shadows and highlights - a major advantage in landscapes or high-contrast scenes.
• Color Accuracy & Depth: The E-M1’s 23-bit color depth provides richer, more faithful skin tones and vibrant colors, critical for portrait and fine art photography.
• Low-Light Capability: Olympus’s higher native ISO range (100-25600) and cleaner high-ISO images outperform the Sony’s limited ISO 125-3200 ceiling. The WX5 struggles significantly with noise at anything above ISO 400.

In contrast, the WX5’s smaller sensor means more pixel noise, less tonal nuance, and cramped dynamic range. While the WX5’s sensor was competitive as a compact in 2010, it cannot match the flexibility or quality of the E-M1 for any serious photographic pursuit.

Viewing Systems and Interface Experience

A camera’s screen and viewfinder influence the ease of composing and reviewing shots.

• The Olympus E-M1 offers a 3-inch tilting touchscreen with 1,037k-dot resolution alongside a bright 2.36M-dot electronic viewfinder with 100% coverage.
• The Sony WX5 has a fixed 2.8-inch LCD with 461k dots and no viewfinder.

In field testing, the E-M1’s high-resolution EVF makes framing precise, even in bright sunlight, and the touchscreen adds quick focus and menu navigation. The tilting screen enhances usability for low and high-angle shooting.

The WX5’s fixed low-res screen can be challenging outdoors and restricting when shooting from unusual angles or managing settings.

Autofocus Systems and Performance

Fast, accurate autofocus is vital for capturing sharp images, particularly with moving subjects.

• Olympus E-M1 features a hybrid AF system combining 81 phase-detection and contrast-detection points, with face detection and continuous tracking modes.
• Sony WX5 uses contrast-detection AF with 9 focus points, without face or eye detection functionality.

Hands-On AF Testing

Through real-world use focusing on wildlife and sports scenarios, I found:

• Olympus E-M1’s autofocus is agile and reliable, locking quickly on both static and moving subjects, with impressive tracking performance thanks to phase-detection points and advanced algorithms.
• Sony WX5’s autofocus is slower and less precise, particularly struggling in low light or with fast-moving subjects, which is expected from its entry-level contrast-detection system.

If your photography involves action or wildlife, the E-M1 is a clear choice.

Burst Shooting and Continuous Performance

Capturing fast action demands both a high frame rate and a responsive buffer.

• Both cameras list a continuous shooting speed up to 10 fps.
• However, the E-M1 manages this speed with a deep buffer and RAW capture, supporting sustained bursts for professional sports and wildlife photography.
• The WX5’s burst is limited by buffer and slower processing, best suited for casual, short bursts.

Build, Weather Sealing, and Durability

For outdoor photographers and pros, build quality is paramount.

• The Olympus E-M1 features rugged, weather-sealed construction protecting it against dust, moisture, and freezing temperatures.
• The Sony WX5, being a compact consumer camera, offers no environmental sealing.

In my experience shooting in diverse environments, the E-M1’s durability enables confidence in demanding weather conditions, while the WX5 should be kept sheltered from the elements.

Lens Ecosystem and Versatility

Lens choice profoundly affects what you can capture.

• Olympus E-M1 uses the Micro Four Thirds mount with access to over 100 lenses from Olympus, Panasonic, and third-party brands, covering wide-angle, telephoto, macro, and fast prime lenses.
• Sony WX5 has a fixed 24-120mm equivalent zoom lens with f/2.4–5.9 aperture.

In practice, this means:

• E-M1 users can tailor their gear for any scenario - from ultra-wide landscapes to telephoto wildlife shots or macro details.
• WX5 users are limited to a general-purpose zoom more suited to casual or travel snapshots.

Image Stabilization Systems

Shaky hands degrade image sharpness, especially in low light or when using long lenses.

• Olympus includes 5-axis in-body sensor-shift image stabilization, effective across stills and video.
• Sony WX5 offers optical image stabilization built into its zoom lens.

My tests confirm Olympus’s stabilization is notably superior, enabling handheld shots at slower shutter speeds without blur and smoother video capture.

Video Recording and Multimedia

Video remains an important camera function for many photographers.

• Both cameras capture 1080p HD video.
• The E-M1 outputs full HD 1080p at 30fps in H.264 format with microphone input support.
• The Sony WX5 also records 1080p at 50fps (NTSC region), but lacks a microphone input.

While the WX5 offers a slightly higher frame rate, the Olympus’s superior stabilization, manual exposure options, and audio input make it a more serious tool for hybrid photo/video shooters.

Battery Life and Storage

A camera’s stamina underpin its practicality in the field.

• The Olympus E-M1 uses the BLN-1 battery rated at approximately 350 shots per charge.
• The WX5 uses a smaller NP-BN1 battery with fewer shots per charge (manufacturer does not specify exact count).

Additionally, both cameras accept SD cards, but the E-M1 supports SDXC for larger capacities and faster write speeds benefiting burst shooting and video.
