Raynox DCR for 72mm lens

Raynox DCR-5320Pro: This is a native 72mm set of converters with a 2 and a 3 dioptre pair. 
The DCR-5320PRO High Definition Macro Conversion lens is particularly designed to use with the high-end digital, film and hi-vision cameras, resulting in a resolution power of 200L/mm at center (MTF 30%) with a low dispersion. With the Macro lens attached on the camera’s lens, it makes possible to approach the object very close for macro shooting. The model consists of two independent lenses, one is with 2-diopter magnification and the other with 3-diopter. It also makes a 5-diopter lens by coupling the both lenses together. Taking advantage of using in three ways, you can shoot the object at the distances of either 50cm or 30cm or 17cm, depending upon the nature of a subject. All lens glass elements are fully coated for the maximum light transmits and fine image quality.
The adapter rings which fit to the 52mm, 55mm, 58mm, 62mm, 67mm, 77mm, 82mm threads (except 72mm) sold separately.
