I am sure that Pentax could resurrect *any* of the FA lenses and modfiy them slightly for digital use.
I use these FA lenses on my K20D and the high resolution of that sensor does not show up deficiencies of these lenses:
FA*28-70 f2.8
FA*80-200 f2.8
FA*300 f4.5
FA20 f2.8
FA50 f1.6
FA31 f1.8
FA43 f1.9
FA77 f1.8
FA50 f2.8 macro
The only problem being that Pentax is now promoting nothing but DA lenses, most of which don't cover FF.
In other terms, if you want recent glass for your new Pentax gear, you HAVE to buy DA and, according to the roadmap, it will remain so for at least a year.
If these are FF compatible, why not make them D-FAs?
My guess is that Pentax didn't plan to have a FF camera for too long and that they developped an array of DA lenses thinking they would only have APS-C cameras to fit.
If they are now thinking to develop a FF cam, they must also be planning to release their new DFAs ... we'll see in the next month/years if something like D-FA* 24-70f2.8, D-FA* 70-200f2.8 comes around but that would mean dumping the nice DA* for the people wanting to go FF: quite an investment!
