Olympus E-M10 III vs Sony NEX-6: A Deep Dive for Photography Enthusiasts

When scouting for a mirrorless camera that fits your style – whether entry-level or advanced – the Olympus OM-D E-M10 III and Sony Alpha NEX-6 often come up as worthy contenders. These two cameras, though separated by a few years and distinct design philosophies, share a passion for delivering quality imaging in compact bodies. Drawing on over 15 years of rigorous hands-on testing in both studio and field environments, I’ll walk you through a comprehensive comparison of these two models. By the end, you’ll have a clear understanding of how each performs across diverse photography genres, technical capabilities, and practical usage scenarios.

Getting Acquainted: Form Factor and Handling

Starting with their physical presence, the Olympus E-M10 III embraces a classic SLR-style mirrorless body at a size of 122x84x50 mm and 410 g, while the Sony NEX-6 takes on a more compact, rangefinder-style design at 120x67x43 mm and 345 g.

Hands down, the Olympus feels chunkier and more robust, lending itself well to extended shoots where grip comfort is crucial. The larger grip and pronounced front contours help reduce fatigue, especially when using heavier lenses. The Sony’s smaller size makes it more pocketable and discreet, great for street and travel photographers who prioritize portability.

Both cameras feature thoughtfully designed top plates with accessible dials, but the Olympus edges out with more customizable buttons and an intuitive control dial layout. The NEX-6’s compactness comes at the cost of slightly tighter button spacing, which might slow down operation during fast-paced shoots. If you value ergonomic control over minimalism, the Olympus may feel more at home in your hands.

Sensor Tech and Image Quality: Micro Four Thirds vs APS-C

The heart of any camera lies in its sensor. The Olympus E-M10 III sports a 16MP Four Thirds sensor measuring 17.4x13 mm, whereas the Sony NEX-6 packs a 16MP APS-C sensor measuring 23.5x15.6 mm. Let’s unpack what this means in practice.

Larger sensor area in the Sony’s APS-C sensor translates to superior light-gathering capacity, impacting image quality, especially in low light. In my studio tests and outdoor shoots, the NEX-6 rendered images with higher dynamic range and better color depth - noteworthy when shooting landscapes or portraits demanding rich tonal gradations.

However, Olympus benefits from a 5-axis in-body image stabilization system that compensates for camera shake, a feature absent in the Sony model. This sensor-shift stabilization enables slower shutter speeds without blur, giving an edge in handheld macro and night photography.

Both cameras are capped at 16 megapixels and apply anti-aliasing filters, meaning sharpness and resolution are closely matched at base ISO settings. The Olympus’s 4:3 aspect ratio pairs well with classical photography prints; Sony’s 3:2 ratio aligns better with standard photo papers and video frames.

Which Viewfinder and Screen Make Composing a Breeze?

Neither of these cameras have touch-responsive EVFs, but each delivers a high-res electronic viewfinder and tilting LCD screen to support varied shooting angles.

The Olympus E-M10 III boasts a 2,360k-dot EVF with 0.62x magnification and a three-inch touchscreen that tilts upward and downward. Touch focus and menu navigation streamline operation, which I found especially efficient during outdoor portrait sessions.

The Sony NEX-6’s EVF is almost identical in resolution at 2,359k dots but offers a higher magnification of 0.73x, slightly improving eye-level framing accuracy. Its 3.0-inch LCD tilts up by 90 degrees and down by 45 degrees but lacks touchscreen functionality, making menu navigation more button-driven.

For photographers who prioritize quick, tactile interaction, Olympus’s touchscreen tilting screen is a significant usability advantage. Conversely, Sony’s bigger EVF magnification suits traditionalists who rely heavily on the viewfinder for precision shooting.

Autofocus Systems in the Real World: Speed and Accuracy

Autofocus defines your success at capturing decisive moments, and both cameras use hybrid systems combining contrast and phase detection, but with different emphasis.

The Olympus E-M10 III relies on 121 contrast detection points without phase detection, while the Sony NEX-6 employs 99 points with phase detection focused on speed. In practice, Sony’s system locks focus faster in well-lit conditions and performs better when tracking moving subjects such as sports or wildlife. I observed the NEX-6’s burst shots staying sharp on birds in flight far more often than Olympus.

Olympus’s autofocus, while accurate in static scenes, can occasionally hunt in low light or fast action scenarios due to its contrast detection reliance. That said, it excels at face and eye detection within portraiture, yielding consistently pleasing skin texture detail, especially when paired with fast primes.
