DC with a close-up mode is designed for this kind of usage. However, most of the SLR type camera users would not use this mode in their SLR camera. They would rather use AV to control the relevant depth of field. Of course, the most convenient way to close-up nature photography is getting a macro lens. It might be optimized to provide its best performance at a magnification of 1:1. A macro lens is able to give higher level of resolution and better magnification. Very small depth of field of close up photography give rise to the essentiality to accurate focus and focus critically on the most important part of the subject as other focal plane may be significantly blurry. Last but not least, high speed shutter can capture and freeze subject that is hardly be caught by human eyes
