Equivalent of Pentax primes on Canon and Nikon FF systems

I have a Pentax system and I have the following lenses.

DA 15 ltd - 520$
Voigtlander Ultron SL II - 400$
DA 70 ltd - 520$

Costs are as they go on Amazon. Lately I have been humoring myself to go to a FF system with Canon or Nikon. I have absolutely NO reason to buy an FF camera but I still want to know the cost involved. Canon has EOS 5D Mark II - 2500$. And Nikon has D700 for about 2400$. Can someone tell me what are the comparable lenses on the two systems? It is OK if the lenses are not as small as the limiteds but should be of the same IQ. I did some research and this is what I found for Canon.

EF 14mm f/2.8L II USM - 2100$
EF 50mm f/1.2L (2100$) or EF 50mm f1.4 USM (389$) - Which one of these has IQ comparable to the DL 40 ltd or the Voigtlander? For those who haven't used Voigtlander, it has a pretty good IQ, right up there with the 40mm limited. So any comparison will do.
EF 85mm f/1.2L II USM (2100$) or EF 85mm f/1.8 USM (400$) - Which one of these has IQ comparable to DA 70 ltd?

I am sure 5D sensor is FF so lesser IQ lenses may look better there. But I just want to know about lenses - IQ.

Also, What are the comparable prime lenses (in IQ) for D700? Appreciate your answer.


cheers,

Abhi

There's the crop factor too so perhaps a 20/24, 60 macro and 100 macro/135 are better comparisons.

Not sure about the IQ of these though

I think you need to leave the Canon L lenses out of your compare to keep it more 1:1 apples to apples. Right now, I don't think Pentax offers equivalents to those particular lenses. Beyond that, I don't think you're going to change your image quality by enough to justify the full frame Canon. Fun to think about if you're lusting after a FF Pentax though.
