Photography - Close Up Macro Lenses

Close-up filters (also known as macro filters) are a filter that screws onto the end of your cameras lens. The main purpose of the close-up filter is to decrease the minimum distance required for the lens to focus. Take the telephoto lens for example. This lens would normally require you to be at least 1.5m from the subject being photographed before the subject will properly focus, but attaching a close-up filter to the lens will let you stand much closer to the subject. Filters can be used together (stacked) or used separately but always remember that if stacking your filters, that the strongest filter (+10 or the highest number filter) is closest to the lens.
Close-up filters are measured in Dioptre. A dioptre is a measure of lens power.
