Voigtlander on pentax

Has any one used vintage Voigtlander lenses on Pentax dslr? I have a Septon 50mm f2 and a Skoparex 35mm f3.4 in superb condition and I see I can get a bessamatic to pk adaptor. Just wondered if it would be worth the bother.

One thing you'll notice straight away is that these lenses don't focus anywhere near as close as we're used to. Even worse is the 135mm Dynarex, with a close focus of 13 feet.

However, they were good lenses, especially the Septon, so probably worth a go.
