The guy has two small, lousy pictures of it too. I think anyone going to spend that much would like a good, large shot of the front/rear elements included.

As much as I like Pentax's big glass, I'll have to pass on this monster. There's a reason why Pentax replaced the f/4 with the EDIF. Too much weight and too much color fringing. Eight inch diameter front element-- Gads!

I'd love to point that one at the sky at night. Lend me it for just a week!
