- BACKGROUND ART
[0002]
Conventional imaging lenses for single-lens reflex cameras are equipped with mirrors, optical finders, etc., so it is necessary to ensure a long flange back regardless of the focal length. However, in recent years, small mirrorless cameras that do not have mirrors, optical finders, etc. have become popular. Mirrorless cameras do not require a mirror, optical viewfinder, etc., and do not require a long flange back. Therefore, in accordance with the compact imaging device, there is a strong demand for the imaging lens to have a short back focus and to be compact, and wide-angle lenses are no exception to this. - Omission
