But you should be aware that the digital sensor of the Nikon DSLRs is smaller than the 35mm film frame of your N75, and so require shorter focal length lenses to give the same field of view that you are used to. Where a 19-35 zoom covers very wide angle for film camera, on a DSLR it gives a moderate wide to normal view. To get the same coverage on a D70s or D200, you'd need a 12-24 zoom. Similarly, the 24-200 and 28-300 zooms work as "all purpose" one-lens solutions for film cameras, but lack any wide-angle capability when used on a DSLR. For wide angle (10-20 or 12-24) and normal zooms (17-xx or 18-xx) you should look at Nikon's DX series lenses, or the equivalent DC from Sigma, Di II from Tamron, and DX from Tokina.
