Has anyone here proven that DA lenses are designed to be sharper than their FF 35mm equivalents? My take on the DA lens revolution was that they are designed to only cover an APS sensor (and secondarily designed to extract more cash from your wallet) and are more controlled in their CA given that image sensors seem more prone to magnify such errors. And as a consequence of the limited image circle the lenses can be designed to be physically much smaller. I guess my theory will be put to test when Pentax releases a DA 600/4 lens.
