Canon financial report for the year 2022 shows the camera business is doing fine
Canon published the full 2022 financial report (see them here). Regarding the camera business they write:
As for the Imaging Business Unit, unit sales of interchangeable-lens digital cameras were above those of the same period of the previous year due to continued robust demand for full-frame mirrorless cameras including the EOS R5 and EOS R6 as well as favorable reviews of the new EOS R7 and EOS R10 APS-C-size mirrorless cameras, despite stagnant production activities caused by a shortage of components. Unit sales of lenses increased owing to strong sales of RF-series interchangeable-lenses that expanded the product lineup.
