Pick the AF Nikkor 85mm f/1.8D if you need a brighter f/1.8 aperture for low light or shallower depth of field, or prefer the more versatile 85mm focal length for portraits. The Ai Nikkor 135mm f/2.8 stays the better choice if you specifically want the longer reach of 135mm for subjects like sports or wildlife, or can work with its slightly dimmer f/2.8 maximum aperture. Both are similarly priced, so the decision hinges on focal length and aperture needs.
