...more specifically an A 50 f/2 and A 50 f/1.7?
Apparently the guy that I got them from (for free) thought that Pentax was dead and gone and that the lenses were worthless, so he tried disassembling them and converting them to another mount or something...
Anyway, he told me that all he did was remove the back silver mount and then put it back, but now the apertures of both lenses are stuck closed and I can't get the aperture rings to turn at all.
Anyone ever worked with lenses like this that could offer me some advice? I know that if I open them up and try to fix them by myself, I'll just make it worse...
Thanks
