noticeably grainy (ZoomPlus).
- Blue range: digital zoom range where the image will
appear grainy.
Because the blue range will not be available at some
resolution settings ( = 67 ), the maximum zoom factor

28 – 1792 mm (28 – 448 mm with optical zoom alone)
• To deactivate digital zoom, press the < n> button, choose
