About 2 months ago I sold my Canon R5 with a couple things in mind.  I knew there was a Canon R5II coming soon and the rumours looked like it might be a camera worth keeping my 500 F/4 II lens to use.  I also figured that Sony would need to come out with something similar in the near future and it is likely that one of those two options will decide what gear I will be using for the next few years.
