    Gda'y Mick, have not used it or don't know anyone who has either, but the specifications are quite good as you can see I have read some reviews and they are quite favourable and to be honest I would'nt mind giving it a go either 8-) Only going to get manual focus even with the 1.4 x tc though.......

    Believe Nicole (on this forum) has one (or had one) in Nikon mount, might be worth PM'ing her. Believe from seeing reports on other forums that they are quite sharp stand alone, but does not take teleconverters well, also the AF is not quite as quick as the Nikon/Canon offerings, but as you are with Pentax, that is probably moot. There are not many other options for the Pentax mount in long glass.

    A Canon mount APO HSM went for $1360'ish on ebay just this last week before Easter. But it was not the DG version. It was originally at $2200 but the guy dropped his price a couple of times to $1300 until he got some nibbles.

    It's almost impossible to find one in a pentax mount .Word is they have stopped making them .have not seen a secondhand one.

    So i bit the bullet today and wired the payment for a new one . $4850 or there abouts plus import duties. Now just amatter of waiting.
