Doesn't it seem to anyone else that these should be branded under their SPORT line? I'm personally not a huge fan of the new nomenclature, but it would still be interesting if these can rival the mark II great whites (especially when it comes to AF and image quality with TC's).
Their new nomenclature is terrible. In my opinion, they should have just stuck to two lines. One for top of the line (Art to compete with Canon's L, perhaps?) and the rest. Alas, their art line has been great so far, so I can't criticize them too much.
