I switched out to digital a few years ago. When I did I sold all of my film gear for some reason, and now I am buying some of it back. My problem is now lenses. I have a couple of older digital Nikons D100 and D1x, but it looks like I will have some compatibility issues with some of the lenses with a F5. I have a Tamron 28-75 2.8 and it is fine I also have a 18-200 that I know will not work with the film camera. I know I will be getting a 70-200 2.8, but am looking for a wide angle zoom. It seems like everyone I look at is for DX not film. I know that Nikon makes them, but I am going to start with Tamron or Sigma and work my way back to Nikkor lenses. Anyone have any suggestions?
