Canon Patent Suggests New Compact Pancake Lenses

Summary

Canon has filed a patent (P2026-52804A) detailing designs for a series of compact f/2.8 prime lenses, including 10mm, 12mm, 18mm, and 28mm focal lengths. These lenses are described as lightweight and compact, suggesting they could be pancake lenses. The 28mm design in the patent closely matches Canon's existing RF 28mm f/2.8 STM lens, though the patent's design appears better suited for APS-C sensors. The patent also describes a retracting lens barrel design for internal focusing.
