With a rather expensive adapter, you can, as Erik says, use Hasselblad V-series lenses -

If you have previously bought a number of V lenses, which have never been "cheap", and a H body, the adapter doesn't really look expensive.
Looking at buying a H body, adapter, and V lenses I agree the total is possibly "rather expensive" but looking at the list or even S/H prices of H lenses "rather expensive" again looks to be stretching it.
Just IMHO as an owner of 6 V lenses and soon to be owner of a H1 (for film) at a price I couldn't have dreamt of ever seeing, thank you digital fans.
