While the R6 II commands a retail price near $2500, the NX30 is now primarily a budget or backup option, available well below $700 on secondary markets. Understanding how these cameras compare within their respective contexts requires dissecting every imaging facet, from sensor architecture and autofocus to ergonomics, system support, and workflow integration.

Sensor Technology and Image Quality Assessment

The sensor is the cornerstone of any camera's imaging capability. The R6 II and NX30 diverge significantly in sensor technology, format, and resultant image properties.

Image Quality Implications:
The full-frame sensor of the Canon R6 II offers approximately 2.3 times the surface area of the NX30’s APS-C chip. This translates to superior photon collection, lower noise levels at elevated ISOs, and enhanced dynamic range potential. In practical terms, the R6 II excels in high-ISO scenarios such as night or indoor photography, offering cleaner images with more recoverable shadows and highlights. The R6 II’s ability to shoot up to ISO 102,400 (native) and extend to 204,800 expands creative possibilities that the NX30 cannot approach without a substantial noise penalty.

Resolution-wise, the cameras are somewhat comparable, with the R6 II at 24 MP slightly edging out the NX30’s 20 MP. However, resolution alone does not dictate image quality; sensor size remains the dominant factor.

The R6 II also benefits from a more advanced sensor stack and improved analog-to-digital conversion circuitry, which manifests in superior color depth, contrast, and latitude in both RAW and JPEG outputs. The NX30, while capable within its constraints, cannot match the nuanced tonal rendering or subtle gradations supported by the Canon.

In landscape photography, for instance, the R6 II's wider dynamic range facilitates capturing intricate shadow-to-highlight transitions, critical when dealing with skies and foreground textures.

Autofocus System: Precision, Speed, and Tracking Capabilities

Autofocus (AF) is a defining performance metric for most photography genres, from action sports to portraits and wildlife.

The Canon R6 II’s autofocus system is state-of-the-art, incorporating nearly 5,000 selected autofocus points that cover a broad percentage of the frame area. Its Dual Pixel CMOS AF II technology facilitates rapid, precise focusing with robust eye detection for humans and animals. This feature alone makes the R6 II ideal for portraiture – delivering tack-sharp focus on the subject’s eyes, even when using wide apertures for shallow depth of field and pleasing bokeh.

By contrast, the Samsung NX30 employs a hybrid AF system developed eight years earlier and focuses on fewer points. While this system was competitive at launch and handles basic AF scenarios well, its subject tracking and eye detection capabilities are inferior to Canon’s modern implementation. The NX30's AF performance lags especially under low light or fast-moving subjects, limiting its effectiveness for wildlife or sports photography.

In practical workflow, the R6 II’s advanced tracking excels at maintaining focus on erratically moving subjects, essential for action and wildlife enthusiasts. The higher burst rates combined with efficient AF tracking ensure more keepers in high-speed scenarios.
