24-85 mm f/2.8-4D make sense on a DX body?
I really like and use the 1:2 macro capability it has from 35 mm to 85 mm.
I use the lens on a D50 and a D200 - both DX cameras.
Yes the 2 AF-D lenses would be manual AF - except when on the Nikon D1, D1x, D1H, D2H, D2X, D2HS, D2XS, D3, D3s, D3X, D4, D4S, D50, D70, D70s, D80, D90, D100, D200, D300, D300s, D600, D610, D700, D750, D800, D800E, D810, D7000, D7100.
The only Nikon DSLRs ever made (so far) without an AF motor in the camera is a much shorter list - D40, D40x, D60, D3000, D3100, D3200, D3300, D5000, D5100, D5200, D5300 - All of Nikon's lower entry-level tier of compact DSLRs.
