I wonder if Focal Method "TurboCal" is using similar technique as "DotTune" to perform MFA prediction in 30 Seconds with no shutter activation in an automated way.
Thanks for the link! I agree, they might be doing something similar to DotTune, provided the Canon SDK+USB interface provides a way to both change the AF tune value programmatically and also feed the PDAF evaluation information over USB to the computer as well.
FWIW, I forwarded a link to this discussion to Reikan some days ago. I have no idea if their method is the same nor if they have acted independently or not.
