Canon does not have to rely on third party Mfgs' for their sensors. They long ago decided it was in their best interest to make their own. Perhaps, it's time to consider manufacturing their own chips, as well, instead of being held ransom due to short supply of same. Of course, this would take quite some time and we do realize that there are other items besides chips that are difficult to acquire, as well, not to mention this would require huge start up capitol. I would love to see a documentary study done, following the total R&D, design and Mfg process involved in bringing a new camera or lens to market, as well as the inherent logistical problems in doing so. Where are you Ken Burns?? Upon reflection, we should note how much we took a normal supply chain process for granted. While we have seen a plethora of fantastic products come to market over the last few yrs., we now have to deal with the reality of limited availability, tempering our demand for wanting it right now, with a little bit (maybe a lot) of patience. I'm working hard to apply the last statement, given our current supply shortages.
