Did this lens come from a movie camera housing or a stills camera and which housing was it designed for?.....if stills what film format? I am just fascinated to know where the adaptor originated from and how old it might be? If the design truly can be used with any lens (excluding fish eye) then it is a very interesting trial indeed!
The upgrade to LR5 was for the D7100, but I had been using LR4 in 64 bit mode. However the problem did not appear until I upgraded to 5.5 in the summer, so perhaps that version needs more RAM? Anyway, I am please to say that it has gone for now!
