Rating: Summary: A103 Close Up +3 Review: Close-up lenses are no substitute for macro accessories such as a bellows unit and extension ring, but they do allow you to take close-up shots covering a subject field with the area of half a postcard, taken at a range of down to around 25cm, with a standard lens. Their main advantage They do not block any light, so they only alter the reproduction ratio and greatly increase the working range of standard and telephoto lenses. For reasons of quality, stopping down to at least f/8 is recommended
