Hey NS, My dad just sent me this piece of glass and I have a canon camera so there is no use for it seeing as there are no pentax->Canon adapters.
Focal Length: 80-200
F-stop: 4.5
The Aperture ring is on the lens itself
Condition:9/10
Pics:
I dont know how much this is worth but Im sure I could get maybe a couple hundred for it so shoot me some offers.
Peace
