Starting October 1st, the price of the Pentax K-1 camera went up by $150 at Adorama and B&H, but Amazon still sells the camera for the old price of $1,796.95. I am not sure if this price increase is permanent and what other products are impacted.
Update – there has also been a K-1 price increase in Europe: from €1,999 up to €2,099.
