thanks i think i got it right. but it was the battery, i thnik.
""" Regarding the lens contacts, i´ll clean them again, i think it can be the problem since it´s very random and the lens mount is a little loose..
plus, the aperture stops have a litle "uncertain " position in between stops, like it does not make the right "click" sound. (complicated)-
by the way, the battery is new and the test light works correctly, but i´ll clean all the contacts again.
I meter myself. and the frames came out completly black, not subexposed.
thans all of you, i´ll kepp you updated and sorry, i cannot quote individually. (where the hell is the individual quote button?)
bye
