I have some older Canon cameras with high shutter counts, but I haven't kept track of the numbers of shutter actuations. Still using a 5DII, but the one with the most shutter actuations is a 7D.
That aside, I have been using a Canon R6 for nearly a year and it already has over 7,000 shutter actuations because of its high shutter actuations per second. By the way, the manual focus between the R6 and the RF 100-500mm lens is amazing. When focusing manually there is a digital focus indicator that turns green when optimum accuracy is achieved. I have been using this lens (above) for close-ups of flowers and other small subjects more than other macro lenses I own. I will have to try some of my EF lenses to see if the focus indicator works as it does with the RF lenses (more than likely it doesn't, however).
