The movement is before the shutter goes after I press the release. It's better when I tether since I release the shutter through Lightroom.

I was trying to calibrate the focus of my lens and nothing was sharp with a 2 second delay. My hand held was way better. I put it on live view fully magnified with focus peaking and it takes 9-10 seconds before all the movement stops.

I found with my 90mm macro if I don't use the 12 second delay on the tripod that the pictures are soft with the SR off or on. With the 12 second delay they are amazingly sharp. Maybe that's something to try.
