DCR-5320PRO 3-in-1 High Definition Triple Macro Conversion Lens....The DCR-5320PRO Macro Close-up lens, particularly designed for use with high-end digital, film and hi-vision cameras, has all lens glass elements fully coated for optimum light transmittance and fine image quality. It is made of two independent lenses, one of 2-diopter magnification and the other a 3-diopter, both fabricated in doublet formula for less color aberration at the corners.Putting the two lenses together, creates a high 5-diopter magnification macro close-up conversion lens with the excellent high resolution power of 200 lines/mm at center (MTF30%). This lens can therefore be used three ways, allowing you to shoot your object at distances of either 50cm, 30cm or 17cm. The lens has a 72mm mounting thread, and adapter rings to fit to 52mm, 58mm, 62mm, 67mm, 77mm threads are sold separately. Please Note: The Model RA7252 adapter ring and RT5267CT Raynox lens holder adapter (not included, sold separately) are required for using the DCR-5320PRO on the Olympus C-8080 WideZoom camera, other cameras may need additional adapters or tubes which are not included
