In contrast, the Sony WX70’s 1/2.3" BSI-CMOS sensor measures a significantly smaller 6.17 x 4.55 mm, with 16 megapixels crammed into this limited 28.07 mm² area - inherently challenging for noise control and high dynamic range capture, despite the higher pixel count.

Industry-standard DxO Mark scores for the Olympus E-5 further illustrate its imaging merits: with a solid overall score of 56, color depth of 21.6 bits, dynamic range exceeding 10 EV, and usable low-light ISO thresholds near 500. While the WX70 lacks DxO testing data, its sensor size and technology imply limitations in low-light flexibility and dynamic range compared to the E-5.

The anti-aliasing filter is present in both models, tempering moiré at the expense of some detail sharpness - a balanced trade-off in consumer and prosumer cameras.

Real-World Impact: The Olympus’ sensor allows finer detail rendition and cleaner files at mid to high ISOs, beneficial for portraits, landscapes, and action. By contrast, WX70 users should expect noisier images above ISO 400 and a more constrained dynamic range, suitable mainly for well-lit environments.

LCD Screens and Viewfinding: Articulated Versatility vs Fixed Simplicity

A key operational facet is the user interface via screens and viewfinders. The Olympus E-5 excels with a 3-inch fully articulated HyperCrystal transmissive LCD featuring 920k-dot resolution, facilitating flexible composition angles, critical for macro, low- or high-angle shooting.

Oppositely, the Sony WX70 houses a fixed 3-inch XtraFine TFT LCD with 922k-dot resolution and touchscreen functionality, streamlining menu navigation and focusing but precluding articulation. The WX70 forgoes any form of viewfinder, necessitating composing strictly on the rear screen.

The E-5’s optical pentaprism viewfinder offers 100% field coverage and 0.58x magnification, delivering precise framing and ease when operating under bright conditions where LCD usage is impractical.

Conclusion: Professionals and enthusiasts requiring flexible framing and reliable optical viewing will gravitate toward the Olympus E-5; casual shooters and vloggers who appreciate touchscreen responsiveness might find the WX70’s fixed screen sufficient.

Autofocus Systems and Shooting Speed: Precision and Tracking Capability

Autofocus (AF) technology profoundly affects portraiture accuracy, wildlife tracking, sports shooting, and street photography spontaneity. The Olympus E-5 incorporates an 11-point phase-detection AF system all of which are cross-type, enhancing focus sensitivity and accuracy across a broad frame area, superior for moving subjects and spot-focus scenarios.

The E-5 supports face detection autofocus with both contrast and phase detection modes, and although it lacks continuous subject tracking, it allows continuous AF mode at up to 5 fps burst shooting.

The Sony WX70, optimized for simplicity, features a contrast-detection AF with face detection and multi-area selection but does not deploy phase-detection AF points. Its continuous shooting reaches a swift 10 fps but lacks continuous AF tracking during bursts, necessitating static subjects or deliberate recomposition.

AF Highlights:

• Olympus’s robust AF system lends itself to wildlife and sports photographers seeking predictable focus locks on erratically moving subjects.
• The WX70’s AF is best suited for casual, static scenes or street photography where reaction time trumps tracking precision.

Image Stabilization and Lens Compatibility: Flexibility vs Integrated Convenience

The Olympus E-5 integrates sensor-shift image stabilization, effective for all native lenses (Micro Four Thirds mount), and notably stabilizes even manual glass, giving users flexibility when using legacy lenses. With a mature Micro Four Thirds ecosystem comprising over 45 lenses, photographers gain expansive focal length choices from ultra-wide to super-telephoto, supporting everything from macro to wildlife.

Conversely, the Sony WX70 employs optical lens-based stabilization within its fixed 25–125 mm (equivalent) zoom lens. While convenient, it cannot match the versatility of interchangeable lens systems.

Lens Ecosystem: Olympus’ compatibility enables targeted investment in specialized optics for portrait bokeh, landscape edge-to-edge sharpness, or macro finesse - a decisive advantage for growth-oriented photographers.

Image Formats, ISO Performance, and Flash Capabilities

The Olympus E-5 offers RAW capture in addition to JPEG, catering to post-processing workflows, critical for professional-grade editing, color grading, and archival quality. Its native ISO 100–6400 range, supplemented with excellent noise control, empowers low-light shooting for interiors, events, and night astrophotography.

In contrast, the Sony WX70 records only JPEG files, limiting editing latitude. Despite a higher maximum ISO 12800 rating, real usability above ISO 800 is compromised by sensor noise intrinsic to its small sensor. Its built-in flash is constrained to a 5.3-meter range versus Olympus’s more robust 18-meter range at ISO 200.

Flash flexibility in the E-5 is augmented by support for external units, critical for studio or fill-flash work, whereas the WX70 lacks such capabilities.
