You can get a much cheaper adapter, with no optics in it, here:

These are not auto-focus adapters (no electrical connections at all, if I am not mistaken), so you'll have to adjust your aperture and focus manually.

Many thanks, (no idea why I could not find this myself)

I have just ordered one & will let you know in the new year how it goes.

I bought the adapter from an shop in Japan.  It was $AU200+, but I think it is worth it.  Being fully manual, the focusing/aperture setting reminds me of shooting on my old 4x5..  However, I get to use my Pentax 645 FA 75, 120 & 200 and the old but wonderful  Pentax A 150mm lens.  I use a tripod a lot so the workflow with focussing etc is not really an issue.

I had wondered what to do with the Pentax body & lenses and this adapter has given them a new lease on life.    I attached two photos - one taken with the Pentax FA120mm and another with a relatively new Sigma 105 F2.8.  They are both similar in terms of focal length & sharpness and the Pentax certainly holds its own with the more modern Sigma lens.  I tested all my other Pentax lenses & they are all similar in quality.  I am pretty happy.

SO many thanks for the sales tip!!
