PROBLEM TO BE SOLVED: To provide a conversion lens unit and an imaging system capable of easily switching the imaging using a phase filter for depth of field expansion method, such as WFC, and the imaging not using the same, while achieving compaction.SOLUTION: A conversion lens unit 10 is attached removably to the lens 7 portion of an imaging device 5 including an imaging element 6, and the lens 7 for forming an image thereon. The conversion lens unit 10 includes a conversion lens 11 to be coupled with the lens 7 of the imaging device 5, and a phase filter 12 which allows for depth of field expansion of image data captured by the imaging element 6 in an imaging optics consisting of the lens 7 of the imaging device 5, and conversion lens 11.SELECTED DRAWING: Figure 1 |
