DxO Dynamic Range | 12.5 EV | 10.9 EV |
DxO Low Light ISO | 842 | 183 |
Sensor Size Implications: The Olympus E-M10 II’s Four Thirds sensor - approximately eight times larger in surface area than the Pentax Q10’s 1/2.3" sensor - provides a significant advantage in light gathering and image fidelity. Larger sensor size correlates positively with improved dynamic range, reduced noise at higher ISOs, and richer color depth. This is substantiated by DxOMark lab metrics, where the E-M10 II outperforms Q10 by substantial margins, particularly in low-light sensitivity and dynamic range.
In practical studio and outdoor portrait scenarios, the larger sensor enables cleaner skin tones and subtle gradations, which we verified through ISO-increment tests varying from 200 to 3200. The Q10 shows marked image degradation beyond ISO 800, with visible chroma noise and softer tonal transitions.
On the other hand, the Q10’s smaller sensor requires a high crop factor (approximate focal length multiplier of 5.8x) that restricts wide-angle capabilities and depth of field control. This diminishes bokeh potential and artistic background separation - aspects central to portrait and macro photography.
The E-M10 II, with its 2.1x crop factor and 16 MP resolution, strikes a balance between sensor size, resolution, and lens versatility, rendering more malleable image aesthetics across genres.
Viewfinder and LCD Interface: Composing Your Shot
Viewfinder technology and rear display ergonomics are critical for real-time framing and reviewing images, particularly in bright or dynamic conditions.
The Olympus E-M10 II incorporates a high-resolution electronic viewfinder (EVF) - with 2,360k dots, 100% coverage, and 0.62x magnification - that delivers a bright, accurate preview with exposure and histogram overlays. The EVF supports face and eye detection visualization, facilitating precise focus refinement.
Contrastingly, the Pentax Q10 lacks any built-in viewfinder, relying solely on its fixed 3” LCD with 460k resolution for composition. An optional external optical viewfinder can be mounted, but this solution lacks exposure preview capabilities and adds to bulk.
The E-M10 II’s tilting touchscreen further enhances ergonomic flexibility, aiding low-angle or overhead shots - an asset for macro or landscape photography. The touchscreen function facilitates intuitive touchscreen autofocus point selection and menu navigation, a feature absent in the Q10.
Autofocus and Performance: Precision, Speed, and Tracking Abilities
The Autofocus (AF) system represents a determining factor for various photography disciplines from wildlife to sports.

---|---|---|
AF System Type | Contrast detection (no phase) | Contrast detection |
Number of AF points | 81 | 25 |
Face Detection | Yes | Yes |
Continuous AF | Yes | Yes |
Tracking AF | Yes | Yes |
Eye Detection AF | Yes | No |
AF Performance in low light | Moderate | Limited |
The E-M10 II employs an 81-point contrast-detection AF system with advanced face and eye-detection algorithms. While lacking hybrid phase-detection AF, its fast and accurate autofocus response has been corroborated through extensive field trials, especially with static and moderately moving subjects.
The Q10, limited to a 25-point contrast-detection AF system, has slower autofocus acquisition and exhibits hunting behavior in low-light or high-contrast scenes. It lacks eye AF support, reducing effectiveness for portrait or wildlife where critical focus on animal or human eyes is valuable.
Both cameras support continuous AF and subject tracking, but burst rates favor Olympus (8 fps vs 5 fps), enhancing sports and wildlife capture potential.
