Size, Handling, and Ergonomics: How They Feel in Your Hands

First impressions matter. The physical design, grip comfort, and control layout greatly affect how enjoyable and intuitive shooting becomes - especially when lingering over moments that require fast reflexes or deep concentration.

Here’s a side-by-side size and ergonomics comparison.

• Olympus E-M10 has a traditional SLR-style mirrorless body, robust and with somewhat more heft at 396g. It measures 119x82x46mm. This larger footprint translates to a more substantial grip, aiding stability, particularly for longer lenses. For photographers used to DSLRs, this shape feels familiar and well balanced.

• Sony NEX-5R embraces a smaller, rangefinder-style, compact body at 276g and 111x59x39mm dimensions. It slips into pockets more easily and is ideal for travel and street photography due to its unobtrusive presence.

In terms of control layout and top panel design, the Olympus offers a straightforward, tactile interface with physical dials for exposure compensation and shooting modes - a traditional design many photographers prefer for fast adjustments without diving into menus.

The Sony uses a sleeker top surface with fewer physical dials and relies more on the rear touchscreen for settings changes. This design fits photographers comfortable with touchscreen navigation and those prioritizing portability over tactile control.

Ergonomics takeaway: If you value solid grip and physical controls, the Olympus E-M10 will serve you better. For minimalists and on-the-go creatives, the Sony NEX-5R’s lightweight, sleek design delivers discretion without sacrificing essential features.

Sensor Technology and Image Quality: The Heart of the Camera

When it comes to image quality, sensor size and technology are crucial. Both cameras use 16MP CMOS sensors, but key differences impact dynamic range, noise control, and resolution.

• Olympus E-M10 houses a Four Thirds sensor (17.3 x 13 mm) giving a sensor area of 224.9 mm².
• Sony NEX-5R incorporates a larger APS-C sensor (23.4 x 15.6 mm), which provides approximately 365.04 mm² area - a 62% increase in sensor size over the Olympus.

Why does this matter? Larger sensors typically gather more light, improving performance in low-light situations and offering better control over depth of field. The Sony’s APS-C sensor benefits from notably better dynamic range (13.1 vs 12.3 according to DXOMark) and superior low-light ISO performance (ISO 910 vs 884 score).

Color depth is marginally better on the Sony (23.7 vs 22.8), which translates into richer tonal gradation and smoother color transitions, especially valuable in landscape and portrait photography.

Maximum resolution also slightly favors Sony’s sensor output (4912x3264 vs 4608x3456 pixels), providing more room for cropping and large prints, though both deliver detailed images satisfying for most enthusiasts.

Real-World Photography: Where Each Camera Shines

Now let’s unpack how these hardware differences translate into the core photography genres.

Portrait Photography: Rendering Skin Tones and Smooth Bokeh

• Olympus E-M10 benefits from the Micro Four Thirds lens ecosystem, famous for sharp, compact prime lenses with naturally stronger depth of field due to smaller sensor size. The E-M10 includes on-sensor phase-detection contrast hybrid autofocus, with 81 AF points. It offers face detection and touch focus via the tilting screen, which makes eye focusing intuitive for portraits.

• Sony NEX-5R has 99 autofocus points, including phase detection, and faster AF performance overall with continuous tracking, but lacks face or animal eye detection (which is common for cameras of this era). The wider APS-C sensor allows for shallower depth of field at equivalent apertures, creating more pronounced subject-background separation and creamier bokeh.

In practice, both cameras deliver sharp portraits with pleasant color rendition. Olympus’ in-body image stabilization (IBIS) helps hand-held shots at slower shutter speeds. Sony’s sensor advantage offers more flexibility in achieving blurred backgrounds without resorting to ultra-fast lenses.

Landscape Photography: Dynamic Range and Resolution Test

Landscape photography demands excellent dynamic range to retain shadow and highlight detail, and ideal resolution for fine texture reproduction.

• The Sony’s APS-C sensor with higher dynamic range better handles scenes with high contrast such as sunlit scenes with shadows.
• Olympus counters with a stabilized sensor and a wide array of compact, quality wide-angle lenses in the Micro Four Thirds lineup.
• Both offer maximum ISO 25600 but real-world usable ISO tops out much lower, with Sony performing cleaner at ISO 1600-3200.

The Olympus’ 12.3 stops dynamic range is respectable but falls short of Sony’s 13.1 stops, noticeable when recovering highlight or shadow details in RAW files.

The tilting touchscreens on both cameras facilitate composition at low angles, but Olympus’ slightly higher resolution LCD enhances live view critical for landscape detailed framing.

Wildlife and Sports Photography: Speed and Autofocus Tracking

These genres hinge on autofocus speed, continuous burst rate, and lens telephoto capability.

• Sony NEX-5R shines with a 10 fps continuous burst rate, combined with 99 AF points including phase detection, enabling faster and more accurate continuous autofocus tracking on moving subjects.
• Olympus E-M10 follows with 8 fps continuous shooting and 81 contrast-detection AF points only, putting it at a slight disadvantage for fast action.
• Lens ecosystem plays a vital role: Sony’s E-mount supports many faster, longer telephoto lenses, often favored for wildlife and sports.

In field testing, the NEX-5R proved more responsive to erratic movement and easier to maintain focus on unpredictable subjects. However, Olympus’ IBIS can aid shooters handheld at longer lenses but cannot compensate for slower AF in tracking rapid motion.

Street and Travel Photography: Discreetness and Portability

• Sony’s compact body and quiet operation make it eminently suited for street photographers seeking a low profile setup.
• Olympus offers more traditional ergonomics and tends to be a bit bulkier, but its tilting touchscreen helps capture spontaneous shots from unique angles discreetly.
