I'm shooting jewellery. I find focus and set the end point, find the closest point and then shoot from camera to infinity. Invariably the farthest point is significantly out of focus to require me to manually reshoot the last frame and add that to the stack - it seems to 1 or 2 "small" inc...

I'm having the same issue. There's a shift once I start shooting.

Canon 5Ds + Canon 2.8 100mm macro. Tried the calibrations and checked camera settings.

Has there been an update on this?
