Optical Zoom vs Digital Zoom
Understanding the difference between optical magnification (real lens movement) and digital zoom (software crop) across the Mavica lineup.
Optical zoom
Optical zoom physically moves lens elements to magnify the subject. This preserves full sensor resolution at every focal length. Mavica models ranged from fixed-focus (no zoom) to an impressive 14x optical zoom on the FD91.
Digital zoom
Digital zoom crops into the centre of the sensor and then upscales the result, discarding outer pixels. On a 0.3 MP Mavica, even 2x digital zoom produces a visibly soft 0.08 MP crop — use with caution.
Mavica zoom ranges
| Zoom | Models |
|---|---|
| Fixed focus | FD5, FD51 |
| 3x optical | FD81, FD83, FD85, FD87, FD100, FD200 |
| 8x optical | FD88, FD90, FD92 |
| 10x optical | FD7, FD71, FD73, FD75, FD95, FD97 |
| 14x optical | FD91 |
When to use digital zoom
On higher-resolution Mavica models (FD95, FD97, CD-series), moderate digital zoom (up to 2x) can produce acceptable results for web-sized images. On sub-megapixel models, avoid digital zoom entirely and crop in post-processing instead.
