    They are using a pressing technique to make some lenses in order to
    reduce the amount of material removed during grinding. While this is
    nice sounding from an environmental perspective, it is not good for
    precision lenses. Finely annealed high quality optical glass is hugely
    compromised by slumping, or molding, or pressing. Lets hope they
    confine it to cheap digicams and not let it come near high-end
    telephotos or zooms. They are also producing the 1D MII boards without
    lead solder to conform to Euro-enviroKOOK legislation against "toxic"
    metals like lead,
    cadmium, etc. New 1Ds owners should be on the lookout for electrical
    faults for the first year
    of camera production using new solders.
