  1. Hi,
    thank you for amazing job you did for all DIYers, I have a handy advice for someone as stupid as me who did not mark position of the coaxial bushings 😦
    You can connect your camera to PC via USB cable through EOS utility and turn on PC live view mode and 200% zoom, now you can set up lens coaxiality in few seconds with no headache 😉

Opinion, question?
