At first this didn't seem much different from autofocus lock (that even dead systems like Contax have!
BUT, it now appears TF will adjust the focal point for a point (eyes) by using one or two pieces of info;
the angle of tilt; this is enough if the subject and camera do not change planes (it would adjust a 45degree tilt by 1.4 setting the lens 40% farther. Actually, this would ONLY work if you moved camera to have BB in focus.
Using tilt angle and the new focus point (belly button!
it would add 40% to the NOW focus distance.
So which is it? one or both?
or is there a third method? (I assume the purpose is nothing more than adjusting for the tilt. Since Phase already have horizon, it seems a similar inclinometer could be used and TF could be done in the Phase/Mamyia set as well.)
Hard to see how this is an advantage over AF lock.
