If Pentax can't sell lenses to their customers, unless they're launched below the street price for an old 3rd-party Sigma lens, they can stop their business and go home.
Or, better, find other customers.
Timothy, I don't buy into that "based on old telescope designs, so it's optically average and cheap" thing. But let's wait and see the actual press release and price; maybe you'll have a surprise (I can't imagine what will happen on this forum if the lens will actually be very good, and pricey
).
Which "expensive optical technologies" are lacking, and how on Earth could you find out, from that one picture? And what extraterrestrial technologies is that Sigma using, because I'm only seeing 2 ED elements and a more complex design, due to it being a telephoto...
L.E. On the other thread it appears the 560mm will also employ 2 ED glass elements (and somehow I believe it's true
) - so it's all down to extraterrestrial technologies. Maybe a flux capacitor?
