No, the Porst is the same as the Tomioka/Revuenon/Yashinon lens that you can find on Kevin's Cameras for $650. It is indeed a very nice lens, as good as the Pentax IMHO, with good contrast and color, even wide open. The bokeh is outstanding, but this has driven the price that people are willing to pay for the Tomioka version to insane levels. Fortunately, the Porst version is much less sought after, because it comes only in Pentax K mount, while the Tomioka comes in M42 mount, which makes it easier to adapt on various brands of DSLRs.
Here are some samples from the backyard, all taken wide open:
