Canon Can't Meet the Demand for RF Lenses

These lenses include: Canon RF 14-35mm f/4L IS USM Canon RF 100-500mm f/4.5-7.1L IS USM Canon RF 100mm f/2.8L IS USM Macro Canon RF 400mm f/2.8L IS USM Canon RF 600mm f/4L IS USM In its statement, Canon Japan said that orders had exceeded expectations and apologized for any inconvenience.
