@Richard: good alternative and not so expensive. How does it work out? Lens + adapter on camera = manual settings? How do you focus? And can you still use the light meter from the Sony camera?
BTW: would be nice to use my old Nikon glass as well. I have some very old beauties ;-)
Are these adapters expensive?
@Cliveh: might be ..... not sure yet ..... and maybe Richard came up with a cure .....
