Don't know where you're going with this "used to call it" or "shmo" stuff, but I assure you that they still call hot mirrors "hot mirrors".

Quite untrue. An AA filter reduced resolution. It expands sharply focused points of light to out of focus squares of light (yes, squares, and I'm not going to launch into the physics of it).

No. The sharpness difference, as I pointed out earlier, is at least 40%. One full paper size. It's just like a lot of 35mm work. Acceptable at 8x10, marginal or unacceptable at 11x14.

More than enough people would buy it to keep a small shop running quite comfortably. You don't even understand the filters, don't pretend to understand the costs.
