Okay, I know CF is like voodoo math. I get that. But I always thought CF had as its baseline the area covered by a
full frame still camera lens. Otherwise, there's nothing to base the "factor" on.
So my question is: If the PC is designed for an MTF lens, does one need to apply the 3.02 factor to
that lens or only full-frame lenses? It seems that if an MTF lens is
designed for a smaller sensor and a "full-frame" lens is designed for a larger sensor, the two should not have the same CF and the MTF lens ought to come closer to matching the sensor size. Yes? No?
Is it fair to say that CF really means that only a portion of the middle of the "projected image" from a given lens falls on the sensor and the rest falls outside the sensor? So the image seems to have been virtually zoomed in.
Too much info, not enough conclusions.
Thanks!
