Venting re" Full Frame

So, as many hear may have noticed, I switched from my Canon 5D mk II to Pentax K-5 last year.  Overall, I am pleased with the change for all things natural light.

But, I find that in studio, I really, really miss not having a full frame outfit.  Both from a resolution standpoint for beauty work (which is a small gripe), but most of all, none of the APS=C lens combos give me the right mix of 50-85mm magnification/angle of view.  I have the 43mm ltd and the 60-250mm for studio work, and neither is really the right workflow for me.  The 43 is slightly too short for serious beauty headshots, and the 60 is too long for my studio sometimes depending on how much of the model's figure needs to be included in the frame...

If only they would get something full frame on the table for the roadmap.  I don't plan to sell anything or completely leave pentax, but I think I might need to save up and get another FF rig for studio work again.  I just want FF and a solid 50MM lens combo in the end.

Does that make sense at all?
