Canon has announced a new patent for a technology that automatically corrects for aberrations in lenses over time to maintain high image quality. Traditionally, this is a technique used to correct for errors in focus detection and metering of interchangeable lenses.
However, in the prior art, it is possible to correct errors related to focus detection, but not aberrations. The purpose of this patented invention is to provide an apparatus that corrects the aberration of a lens device over time, thereby further maintaining high image quality.
Canon successfully copied the German Leica camera in a small workshop in Tokyo in 1934, and also developed the first Japanese 35mm focal plane shutter camera, KWANON.
