I had a bit of a brainwave and realised I don't need to preregister lenses. Thus the latest version of QDFS, download from the right hand link, now works with all EF-M lenses: no lens registering required.
I personally find it best to put the 'Get Mag' menu to Dynamic, which means I can always fine tune the depth of field scale if required, eg near,but short of the hyperfocal.
When switched on or after, say, a focal length change, the script will carry out a lens calibration step, at a distance of a fraction of the hyperfocal, as defined in the menu.
I recommend you always do an additional dynamic calibration yourself, at the start of each shooting session.
As usual I welcome any comments on this post or any of my posts.
