In recent years we've seen the M-9, offered by a revitalized Leica at about triple the price usual for such a full frame body, along with the designer casing and restricted functionality evocative of Apple Computer but with more than a twist of retro love -- at last you can buy new triple-priced lenses without such sissy features as speed or auto-focus. The customers can't love it enough, and fall to almost mystical terms when they try to describe the IQ. (There have been whispers that Leica's unimagined success at the high end has driven many of Canon's top execs into counseling.) Pentax entered digital Medium to raves with the 645D; we have gasped at the entrance of Sigma's SD1 with its Foveon X3 (APS-C) at a stonking $7000, body only. En route is the FujiX-Pro1, a poor person's M-9, in a way, that has the heavies at Luminous-Landscape dancing the frug the twist and the wa-watusi in anticipation. Then there is the expected Nikon 800E...
What these five bodies have in common is the absence of anti-aliasing filters. Stripped of this dulling scrim (some say), an APS-C sensor out-resolves the best full frame, and other aspects of lens IQ leap ahead as well. Moire (they say) is hardly an issue at today's high resolutions anyway and can be eliminated entirely by in-camera digital signal processing (Leica), Fuji's quasi-random 6x6 color filter array or that triple stacking of photo-sites (Sigma).
So tell us, who that knows, just how easy is abandonment of the AA filter, what does Science and Engineering say? Will it be a new dawn? What if anything will Canon offer here?
Finally, is this a case -- for now at least -- in which the interests of still and movie shooters clash? (The lower resolution and higher data rates would make moire more of a problem and harder to manage with the latter, I imagine.) Light: please, heat: not-so-much. I have a foot in both camps. Let us love one another.
