Will any of these work with my D80. They were for her slr film camera YEARS ago. Thanks! And let me know the quality I can expect from them too. Sigma 35-70mm f/2.8 JCPenny 135mm f/2.8 Also she has some other equipment: Vivitar Zoom Thyristor 3500 Flash And lenses that just look to me like lens caps but clear. She said they zoom the current lens you have on. One says +1, another says +4, other is +2. They say "HDYA 55mm" on them. Can I use any of that either? Thanks so much for your help.
