Yep. It's crap. Like those cheap, flimsy polycarbonate windows on the space shuttle.
Sure, let's celebrate that kind of stuff because NASA uses it for very specific applications. Next thing you know they are putting it in as lenses. I just had to get a replacement for a lens that I broke in my eye glasses. The real stuff wasn't available (thanks to the FDA, but that's a whole other issue I can get pretty agitated about). So now I have polycarbonate lenses in my frames until I can get actual Zeiss lenses from a place in Europe. It's exactly that: crap. I feel like I lose about 20% of my vision with this junk. But of course the "specialists" in the store declare me insane, because it's again a "know fact" that a normal person can't tell the difference. It's like MP3 files again.
We are slowly letting go of all the great achievements in these areas so that cheap Chinese manufacturers can make cheap copies or work for the "name brand" companies. And I'm not anti-trade or anything like that. I'm fine with buying things from China if they are good products.
But if Canon is lining things up to include more "engineering plastic" then the only reason is to lower their cost and make the manufacturing process easier and more automated - so that they can move their stuff to China among other things.
Or are we expecting to see any materials like these?

And us fools are supposed to celebrate such a vast improvement because things are lighter now. Yeah. I'm so happy.
Please don't take my response personal. Has nothing to do with you and isn't meant as questioning your extensive technical and photographic knowledge. There are just days where I'm a little frustrated with what's being sold to us as progress while some real opportunities are being missed (which ironically would include NASA and the space programs that have been canned).
