Diffractive Optics is dead

"it would appear that they are both traditional L-series supertelephoto designs that don't utilize the diffractive optics (DO) technology Canon first introduced in the EF 400mm f/4 DO IS USM."

One prime and one zoom - that's what Canon gets after a decade of development. All those much talked about hypothetical lenses haven't been made and aren't in the pipeline.

R.I.P. D.O.
