I'm with brightline here, there's good technical reason to introduce an AA filter. The "trouble" is that in real life scenes, exhibiting a great deal of "chaos," one wouldn't possibly be able to spot a lot of anti-aliasing artifacts because we have no idea what is supposed to be there and what is not in the first place. That's exactly why it's only clearly visible in places with super-regular structures like the side of the tram. I'm convinced there's a great deal of aliasing in all those pictures, but alas, how would one notice e.g. in the trees?



Interesting would be a side-by-side shot of something similar to FIG. 1 on the wikipedia page on aliasing here: http://en.wikipedia.org/wiki/Spatial_anti-aliasing
