Just tried it again. I have an EOS 50. Pressed trigger 1/2 way and waited
then taped the tripod leg as I hold the trigger 1/2 way.
I see vibration. I see vibration each time I try.
I see a little vibration in the display information but more through the
lens.
Done on kitchen floor. With a cheap Velbon 900 tripod.
Did you see vibration with the IS off?
