    Removing the thing physically would do more good. There's something in the laws of physics that says that you can't regenerate information that has been lost ... but a software anti-alias filter is easily applied, if you really need to do so.

    Why drive with pressure on both brake and accelerator pedals?

    Agreed.

    Bit like raw and jpg.

    With raw you can generate a jpg but you cannot go the other way because you have lost the other bits of data.

    Sounds likely but given Nikon have botched it too why bother going to the expense of doing it properly (like Leica?). Presumably the Canon software botch will work with other cameras but the Nikon hardware botch is expensive and will only ever work with the cameras the factory install it on.

    Aye, sounds a bit like saying you just add more elements in a general purpose lens to correct abberrations and make it better......it's never going to be as good as not needing to correct as much in more specialised lens. (for example my 70-200 isn't as good as my 90mm even although the zoom lens is about 30(?) years younger and costs twice as much).

    GIGO?

    Isn't this the same story as "Canon fights Nikon D800E with software" or am I getting confused?
