Pentax 645 with Hasselblad lenses

[Gundus]

Hi,

Does anyone has this set-up? Pentax 645 body with Hasselblad lenses (with an adapter ring) My doubt is about focusing...Are the focus distances scales in the lense correct? The f/stops are also correct? Can i use the hyperfocal like it was an original pentax lense? or do i have to make an adjustment? If yes, what kind of adjustment?

Thank you in advance

I've not used that set-up, don't have a Pentax and adaptor to try it with.
But, as for the scales, the body won't matter, the scale and the f/stops will be correct, IF the adaptor is the right length to allow the lens to focus at infinity.
It depends on the adaptor, but it shouldn't be a problem on a camera like your 645.
The Hasselblad lens has a DOF scale, you can use that for hyperfocal focusing.
