Yes, because you assumed I meant to say perspective and erroneously said compression, when I meant to say compression; assumption is the mother of all ****-ups. The two do mean different things, and I meant what I said.
First off, the part about the 100 not giving the same compression as the 70-200 is simply a failing in reading comprehension on your part; the—I assumed obvious—implication being that the zoom can be used at 200mm, creating a very different look in both compression and perspective than the 100mm is stuck at. Hence, the 100 can't give you the compression of the 70-200. The 70-200 can give you the compression of the 100, but not vice-versa.
Second, perspective and compression may sometimes be erroneously used to mean the same thing, but they are not, and I use each with purpose. Perspective is fully-ranging, while compression is only used to describe a difference in information density. I generally won't mention perspective because I—again, perhaps too-optimistically—assume people are familiar with the perspective of any given focal length at any given distance and it varies too much from use to use to be worth talking about. Compression, however, is the same for any given focal length no matter where you're shooting from and can not be replicated by cropping other focal lengths. (Well, except for mirror lenses and microscopes, but that should be a given.) The density of information—the compression— passed to the sensor is different, even if the view of the subjects—the perspective—is the same. Just as the contrast and colour can be different. (Though of course that's more subject to a specific model basis.)
You're talking about and to someone who got Fuji's UK marketing to delay advertising by a week to fix their misuse of "strobe" and who has ranted in the face of Scott Gilbertson (then CEO) about Fender's horrific confusion of 'tremolo' and 'vibrato', so no, I'm well acquainted with and against the folly of abusing terminology, but I'm also equally against presumptive accusations.
