As Canon's latest lens technology innovation, I'm sure DO is a matter of interest to many besides myself. My thought is that we can use this thread as a link point to information on the lenses and technology as it comes available.

Sound good? I'll start it off with these three links:

A link to a very good overview by Canon, on Multi-layered Diffractive Optical

dpreview article on the 400mm DO

Canon (Malaysa) press release

I think the technology is very promising, but I'm still very concerned with flare (all those angles & edges to catch stray light)!
