This lens makes absolutely no sense to me, and should probably be another one of those patents that will never see the light of day.
I just canÂ´t see how such a lens could surpass the current 16-35, particularly considering the weak IQ (lack of contrast, sharpness and sometimes terrible halo fringing), not to mention the hefty pricetag that is normaly associated with DO.
It seems that presently the only real advantage of DO is the ability to reduce the size and weight of a lens, which in this case is not really an issue.
However even with it's current flaws and shortcomings I do think that the DO technology is a very interesting concept and if properly developed could breed some great lenses in the future, specially if applied to long super telephoto lenses.
The 600 f5.6 DO patent that was issued some time ago seemed to make a lot more sense and if produced could be a very good solution for someone (like me !) considering a very long focal length that is still compact and handholdable.
