Would it be able to run a script that would-
A.) Change the Aperture one stop at a time over 2 seconds or so
And
B.) Change the ISO or Shutter to compensate for the exposure change.
The effect would be a rack focus of the depth of field while maintaining the same exposure.
Example of use
You could have thin focus on someone's face with a blurry background, a new person walks into frame and then you could have them both in focus by stepping down.
