5.3. SAFOX13 AF System

The enhanced SAFOX13 AF system expands the autofocus points to 101, providing a wider AF area, faster response, and highly accurate subject capture.

5.4. Pixel Shift Resolution System

Utilizing the in-body SR II mechanism, the Pixel Shift Resolution System captures four separate images by shifting the image sensor by a single pixel for each, then synthesizes them into a single composite image. This process obtains all color data for each pixel, resulting in super-high-resolution images with finer details and more accurate colors, while also reducing false colors (moire).

5.5. Compatibility with Classic Lenses

The K-3 Mark III supports manual input of lens focal length for classic lenses, allowing for accurate metering and saving aperture values as Exif data. It also accommodates TAv mode.

6. Qualitat de la imatge

The camera features a new back-illuminated CMOS image sensor with approximately 25.7 effective megapixels and a low-pass filterless design to maximize resolution. Combined with the PRIME V imaging engine and accelerator unit II, it achieves excellent descriptive power across the entire sensitivity range, with multi-dimensional image space filtering reducing noise while preserving fine contours.
