No apologies needed. I actually really appreciated the feedback.
My thoughts are quite early so no major loss in ego
- I do however think there is a Project there, it just might take a whole new level of thinking that may involve modification to the lenses themselves.
Ultimately, I have a big legacy lens setup that needs to be as good as it can be for FF digital. The questions I am exploring is 'what is the gap between legacy and new lens technology (including lenses yet to be released by Pentax)?' AND 'Is there something I can do to improve my lens collection without incurring the big cost of new lenses'.
So, early days yet. I know that I could install ED/ APO glass in some of my existing lenses for a fraction of the cost of a new comparable lens. The wustion was can I do it in an adapter instead. Perhaps not, but perhaps the Project is more a question of aligning the lenses to the adapter. So part modification for the lens (perhaps one ED element) and the rest of the modification in the adapter.
With regards ot hte adapter I wonder if the lens design for hte latest Pentax teleconverter is useful. Perhaps that might be a worthy consideration.
