Quote: The focus stacking feature will shoot 8 photos at the focus positions you set and then merge them into one jpeg file at full resolution. Achieving good results will take some experimenting since so many variables are at play - subject size, distance from subject, lens choice, aperture setting, and focus differential. All eight photos are recorded plus the final stacked image.
From this quote I understand that the camera stacks a set of photos that cover a depth of focus range, and were obtained by automatically spaced focusing with the camera itself. This is not identical to stacking photos created by spaced focusing with the microscope, since the microscope image is optimal when the camera and eyepieces are parfocal. So I am not sure that in-camera automatic shooting-stacking can replace the integration of microscope focusing with shooting, then stacking.
