While reading a report on the Kodak Pro/C (Sigma-body with EOS 
mount), I read that this one *can* correct the aliasing problem that 
occurs with certain lenses, wide-angles in particular (because of 
increasing angles of light falling on pixels that were not designed 
that way, triggering two pixels were only one should be).

Default it recognizes most available lenses, but one can also create 
a dedicated custom 'correction-table', and I think it reads as if you 
can then 'attach' this particular table to a certain lens (assumed 
that particular lens can be recognized by the camera of course, can't 
work with all-manual lenses/adapters, you will have to 'force' a 
correction-table there, but still pre-set).
And it stores this correction-table on the memory-card.

Although the report ends with the conclusion that still not all 
aliasing problems are gone....maybe the default tables are not 
perfect, and aftermarket can do better in creating one?

And, perhaps most important:
In a way, this is also one step closer to my favorite lens-specific 
recognition+action: focus correction for IR, depending on IR-
sensitivity and filter used.

Now we only have to convince the camera-designers to make the IR-
block filter removable, instead of requiring an expensive 
modification (or preventing any solution, by sandwiching the IR-block 
filter onto the sensor, like with the 1Ds (bastards, the 1D can be 
modified, the 1Ds can't)).

(oh, and it must also allow some kind of in-camera mounting of the IR-
pass filter, like the BetweenTheFilmRails solution with analog 
camera's (or analog-based digicam's, like 
DCS-1/3/5/520/560/D2000/D6000)
