ARRI Alexa 65 and Panavision DXL cameras are not for sale. They are only available for rental from ARRI Rental and Panavision respectively.
Sony don't manufacture the F65 anymore, so you won't find a current list price. It originally retailed for $65k for the camera body, and $20k for the SR-R4 recorder, so basically $85k. [1]
