Per your message below, it is simple. You just need a set of closeup lenses
manufactured by Tiffen Optical and others. You need to know the filter size
of your camera's lens (i.e. 52mm, 47mm, etc.) to order the correct lenses.
Usually a set includes a +1, +2 and +4 diopter lens which can actually be
combined to get super close. There are also variable closeup lenses, but I
prefer the individual lenses. They are available from just about any camera
store (look in the back of magazine like Popular Photography).

Best regards,
Jim
