Macro, or, as some may prefer - micro photography, is all about taking pictures of small objects. Full frame DSLRs have 35mm sensors (36 × 24 mm) and the less expensive ones have a cropped sensor size, so with a macro lens, ideally, an object as small as the sensor size can be captured without any reduction in size. This creates immense number of possibilities, making simple and small objects blow up on a computer screen or on a printed paper, and is ideal for taking photos of insects and flowers.
