For macro photography (close-up imaging) you can focus up to 3 cm from the in-built lens
without additional optics. This results in a field of view of about 39 mm x 29 mm using a

no physical iris aperture to adjust field depth). Figure 2.3 shows an example image
captured with this macro setting.

Limitations of the AF51
Highest magnification imaging
The wide fixed angle lens and very wide field of view mean that this camera is not
recommended where extreme high magnification is required. For example, it is not the
