BH is taking orders for the Pentax A 400/5.6. Probably just existing stock. I doubt if Pentax is turning out more copies, but you can still get a new one. Of course you can get a used one for less than half the price of new. Paul -- Original message -- From: John

Hi every one! Is there any one on the list who owns (or used to own) a Pentax K 400mm f5.6? If there is I would be so obliged if you could tell me some things about it, namely, how sharp it is wide open, and whether or not it has noticeable CA (wide open). I have found one relatively cheap
