What are the exact focus stacking increments?

In the Case Remote application when doing focus stacking, you are presented with the options to increase or decrease focus in steps of 1, 2 and 3. These numbers represent small, medium and large changes in focus. The exact change of focus, depends on the camera and camera manufacturer. These amounts are not published by camera manufacturers and therefore we can not tell you exactly how much focus will change. Our best recommendation is to experiment and find the setting that works best for you and your specific shot.
