Ok, this may be a little confusing...or perhaps someone will know exactly what I'm talking about. With my experience with lenses particulary with SLR camera lenses, but I'm sure the same hold true for video lenses, it seems as though upon focusing between subjects they distort(or maybe un-distort)/move as they are coming into focus. BUT, many recent commercials I have seen the lenses seemed to have improved greatly on that aspect in that they do NOT distort but just shift focus. Any idea why? Or any idea what I'm even talking about? Thanks
