Both cameras emerged in the mid-2010s, offering innovative features at their price points, but with very different sensor sizes, autofocus systems, and ergonomics. Having tested thousands of cameras over the years, we’ll dissect each model’s strengths and weaknesses across major photography genres, technical performance, and practical usability - helping you make an informed choice tailored to your creative ambitions.

First Impressions: Design, Size, and Handling

The Olympus E-M5 II and Sony A35 offer specialized body designs that influence your shooting experience.

• Olympus E-M5 II: This mirrorless camera embraces a classic SLR-style body but remains notably compact (124x85x45 mm) and lightweight (469 g). The magnesium alloy build feels solid and weather-sealed, a big plus for shooting outdoors in adverse conditions. Its fully articulating 3-inch touchscreen enables flexible shooting angles - fantastic for macro and video work.

• Sony A35: Coming from an SLT (Single-Lens Translucent) DSLR lineage, the Sony packs a slightly larger and thicker body (124x92x85 mm) but remains comfortable to grip thanks to its deeper handgrip. Weighing 415 g, it’s lighter by about 54 grams, although the build lacks weather sealing, which may limit rugged use.

The ergonomics favor Olympus for versatility and outdoor conditions, while Sony may appeal if you’re comfortable with a traditional DSLR feel and require a slightly weight-optimized package.

Control Layout and User Interface

A seamless shooting flow often depends on intuitive controls:

• Olympus E-M5 II: Features a well-thought-out control scheme. You’ll find a dedicated front and rear dial, customizable function buttons, and an easily accessible mode dial on top. The touchscreen lets you quickly set focus points and playback. Although the buttons are not illuminated, their tactile responsiveness is appreciated during manual adjustments.

• Sony A35: The control layout is straightforward but more basic. A single top command dial, limited customizable buttons, and a fixed LCD (without touchscreen) are standard. It supports live view but lacks the touchscreen convenience, which can slow down focus selection and menu navigation.

For fast-paced shooting or those who like direct manual tweaking, Olympus provides more ergonomic flexibility. Beginners transitioning from point-and-shoot cameras might find Sony’s simpler interface less intimidating but somewhat restrictive.

Sensor Technology: Impact on Image Quality

Sensor size greatly impacts image quality characteristics such as dynamic range, noise performance, and depth of field:

The Sony’s APS-C sensor is significantly larger, offering better low-light noise control and more depth-of-field control for subject separation - a critical advantage for portraits and shallow focus effects. The dynamic range advantage also benefits landscape photographers who want to extract detail from shadows and highlights.

Meanwhile, the Olympus E-M5 II’s smaller Four Thirds sensor is balanced by excellent 5-axis in-body stabilization that compensates for lower light sensitivity by allowing steadier handheld shots.

In practice, both cameras produce clean, vibrant 16MP files, but the Sony pulls ahead when pushing ISO limits beyond 1600 due to its larger photodiodes.

Viewing Experience: LCD and Viewfinder

How you compose and review images greatly affects your shooting workflow:

• Olympus E-M5 II: Sports a 3-inch fully articulating touchscreen LCD with 1,037k-dot resolution. This screen rotates upwards, downwards, and sideways - perfect for shooting from awkward angles, self-portraits, or vlogging. The touchscreen functionality extends to focus point selection and menu navigation.

• Sony A35: Also features a 3-inch screen but fixed (no articulation) and with lower resolution at 921k dots. No touchscreen - you must use buttons/dials for navigating menus and focus.

Viewfinders are both electronic, but Olympus boasts a sharper 2.36M-dot EVF with 0.74x magnification, vs Sony’s 1.15M-dot EVF and 0.73x magnification. The E-M5 II’s EVF provides a clearer, more detailed viewing experience in bright light and for manual focusing.

If you value flexible screen angles and a crisp EVF for composing in variable conditions, Olympus takes the edge here, especially for travel and macro shooters.

Autofocus Systems Compared: Speed, Accuracy, and Tracking

Autofocus can make or break the capture, particularly when shooting fast-moving subjects:

The Sony A35 uses Sony’s SLT fixed mirror phase-detection autofocus, which excels at quick, predictive focusing for moving subjects - crucial for sports and wildlife photography. However, with only 15 focus points, tracking smaller or erratically moving subjects can be inconsistent.

Olympus relies on contrast-detection with 81 focus points, providing precise focusing accuracy, especially good for static subjects, macro, and landscapes. Eye detection and continuous autofocus performance are solid for portraits and video.

If you shoot action or wildlife and need speed and predictability, Sony’s phase-detection AF offers advantages. For detailed static or creative work with flexible manual override, Olympus’ system will feel more precise but slower.

Image Quality in Action: Sample Photos and Real-World Performance

Here we include representative shots captured with both cameras under typical conditions such as portraits, landscapes, and low-light scenarios.

• Portraits: The Sony’s APS-C sensor creates shallower depth of field, yielding creamier bokeh and softly separated skin tones. Olympus’ images are crisp with well-controlled noise, but subject isolation is less pronounced.

• Landscapes: Olympus benefits from excellent in-body image stabilization enabling sharper handheld shots at lower shutter speeds. Color rendition is vivid and natural. Sony images show wider dynamic range and finer detail in highlights and shadows.

• Low Light: Olympus’ 5-axis stabilization and sensitivity to ISO 1600 produce usable images with smooth gradations. Sony pushes ISO higher with acceptable noise levels but can exhibit more chroma noise at top settings.

Overall, both cameras meet enthusiast needs, but your subject and shooting style will guide the best choice.
