I just bought the Nikon D5000. However, I have an old Minolta X-700, you know, the kind that takes 35MM film. I have not had it out of the case in over 30 years. I have 3 lenses, and of course they don't work on the Nikon. I was wondering if they have any value or if they would work on any of the newer digital cameras. One of my favorite lenses was the zoom, a Promaster Spectrum 70-210 MM. Such a waste that they have no use whatsoever to me, looking to get rid of everything. Any suggestions appreciated.
