Hi and here I have an interesting question I started foolling with an ftn back in the 70's and was sorta fair at it. Life came along an things went astray recently I bought a D200 mainly because I could us my old non- AI lens(s) setting up with my little 50mm or my small sigma 35-85 zoom works like a charm. BUT I recently required my old Soligar 300 from my daughter here is the issue …when I set it up the light meter does not work at all as the others do. Does anyone have any insights?? Thanks in advance!!
