I want to save while shooting in continuous time-lapse mode.
It depends what your time-lapse interval is.
There are two ways that SDM supports.
The first, uploads all taken images at certain intervals. On switching to playback the lens retracts every time although someone has posted a sort-of fix for that.
The second way starts-up an image-capture programme on the PC.
Someone is testing that as I write, an American University has the camera connected to equipment that photographs the eye.
