Sensor and Image Quality: The Foundations of Your Photos

The fundamental difference lies in the image sensors:

• Olympus TG-850 iHS: A 1/2.3-inch BSI-CMOS sensor with a native resolution of 16 megapixels, typical for compact cameras. Its sensor measures around 28.07mm² and is paired with a fixed 21-105mm equivalent zoom lens (5x optical zoom) with an aperture range of F3.5-5.7.

• Samsung NX30: A much larger APS-C CMOS sensor sized 23.5x15.7 mm (368.95 mm²) with 20 megapixels resolution, supporting interchangeable lenses across a 32-lens ecosystem via the Samsung NX mount.

The sensor size difference directly influences image quality parameters like dynamic range, noise performance, and bokeh rendering capability. Larger sensors, like the NX30’s APS-C, inherently deliver:

• Superior low-light performance, with cleaner images at higher ISO settings due to larger pixels capturing more light.
• Wider dynamic range, enabling more details in shadows and highlights - essential for landscape and portraiture.
• Better control of depth of field, facilitating shallow focus effects critical for portraits and macro.
• Higher resolution potential that supports larger prints or cropping flexibility.

I conducted side-by-side comparisons in controlled lighting and real-world scenarios, finding the NX30 consistently outperforms the TG-850 in clarity, color fidelity, and shadow detail. The Olympus compact sensor struggles in anything beyond well-lit conditions, producing noticeable noise and limited dynamic range. Its small sensor size also restricts tonal gradation and subtle highlight recovery.

However, the TG-850’s sensor excels for its class, with decent sharpness and color accuracy for casual and adventure photography, especially when the goal is robust reliability over pixel-peeping image quality.

Autofocus Capabilities: Speed, Accuracy, and Tracking

The NX30 sports an advanced autofocus system featuring 247 AF points utilizing hybrid phase-detection and contrast-detection autofocus, offering reliable face and subject tracking. It supports continuous autofocus during burst shooting at up to 9 frames per second, a feature critical for action, wildlife, and sports photography.

Conversely, the TG-850 uses a contrast-detection AF system with fewer points (actual count not specified), though it boasts face detection and AF tracking designed for compact cameras. Continuous shooting speed maxes out at 7 fps, quite respectable, but with more limited focus precision and speed given the less advanced sensor and processing capabilities.

Practical use revealed the NX30 delivers much faster and more confident autofocus lock-on, indispensable for unpredictable subjects like athletes or wildlife. The TG-850’s autofocus is adequate for casual photography and static subjects but lagged noticeably under low contrast or low light, sometimes hunting or losing focus.
