I find this statement a bit dubious: \"Another way to look at it is most consumer cameras have the filter while more prosumer (or pro) level cameras lean towards not having it.\"
No professional DSLR from Canon/Nikon has been without an AA filter so far. If the D800E can be called a professional camera, it\'s the first one with a filter that doesn\'t do AA. Leica M cameras aren\'t particularly aimed at professionals either, so that means you\'re left with medium format cameras, and I don\'t think it\'s an established fact that they don\'t have AA filters because it\'s so beneficial for IQ.
Tip: include a sample image of moiré to illustrate the phenomenon.
It also seems that you completely missed the point that Leica doesn\'t use an AA filter and the thin IR/UV filter in order to minimize IQ degradation due to the extreme ray incidence angles of rangefinder lenses. The blurring due to the AA filter in itself wouldn\'t really be a problem if the exit pupil of (esp. wide angle) rangefinder lenses wasn\'t so close to the sensor. So effectively, you\'re explaining what an AA filter does, but not the main reason why Leica isn\'t using one.
