well it wasnt too bad at 5.6...Pentax forum does some pretty decent reviews and I dont sense they are very biased.
But the issue is the price... Given that this is a telescope design with less optical elements, it has to cost less than the Sigma f4.5 500mm. Had they released this lens at about $4K, it would make more sense. I cannot fathom who would buy this at $6-7K
