Since I purchased this body new I and I know the number of times it has rolled over the 10000 counter I am sure I can be within a couple actuations of the exact number. Now if you use the counter differently and reset it when you change cards for example it gets more difficult. But I had never see this "Less Than" Actuations menu item before today. I have had this body since October 2016.

While there have been some interesting attempts at finding shutter count using such web sites, none have ever given me a true reading on actuations. I have sent my Canons to Canon in Irvine California. They charge $30 for a count alone. If the camera goes in for other service, and if I ask, they will give me a courtesy shutter count. A sensor clean will afford me a courtesy shutter count.
