Minolta MD MC Lens to Nikon F Mount Adapter Ring with Glass for D3000 D5000 D700 | eBay
Actually, those lenses are not worth very much money at all, so best not to spend too much money on them. And besides, you should be able to replace all three with comparable lenses for under $75. The NICEST thing about the "baby Nikons" is that they will mount and shoot with "old" F-mount lenses, the kind that many pawn shops have piled up....old JC Penny and Rokinon and Quantaray 35mm f/2.8 and 135mm f/2.8 and 70-200 f/3.8 zooms....all those old, 1970's-era classic primes and zooms...will WORK on the "baby Nikon" models. NO metering and no automatic flash control, but they will mount, and the lenses will stop down automatically to shooting aperture, and they WILL function.
A good many of these old 1970's and 1980's 3rd-party lenses, like the JC Penny brand, or Rokinon or Quantaray or whatever silly name they had,
retail for $10 to $20 at most. In prime lenses, like 35mm f/2 or f/2.8, and especially 135mm f/2.8, the quality is pretty decent, and quite comparable to a $200 lens made today.
The D40, D60,D3000-series, and the D5000-series cameras ALL will accept basically all F-mount lenses and accessories without modification, no matter what era they were originally made in!! That makes the baby Nikons excellent cameras for experimenters and hobby shooters who want access to all that old glass.
