I don't have any concerns about the shutter life of my R5!Your R5 shutter is rated at 500,000 actuations. That's an awfully large number of butterflies before it needs replacing.

Getting back to shutter life expectancy, I've never been clear (and neither have the manufacturers, AFAIK) about what constitutes an "actuation".
With mechanical, the shutter is open for viewing, then closes, then opens for the exposure, closes again to end the exposure, and then reopens for viewing - so does that count as 4 actuations, or 2, or one?
And what about EFCS, where the shutter just closes to end the exposure, and then opens again for viewing?
If a shutter lasts for 500,000 actuations with mechanical shutter, presumably it will last for 1,000,000 actuations with EFCS?
