As I understand it, the 14mp Kodak had a user=20
removable AA filter, did it not?  Not sure about=20
that.   In any event, as to the first, I stand=20
corrected.  However, according to Kodak's website, as of May 13, 2005

Thus, I believe I am still right in saying that=20
the M8 and DMR are the only available sub-MF=20
cameras without a low-pass filter.

You might be right about two camps and unbalanced=20
discussions.  I have not followed such=20
discussions and have spoken only from my own=20
experience.  Still, I have done a fair number of=20
architectural shots with the DMR and not found=20
any problems with Moire patterns.

Thanks for the update on the 14n.
