AF Problem Nikon D90 with Nikon 50mm F/1.4D and Nikon 85mm F/1.8D

Back before I acquired my Nikon D90 I always put my trusty 'bokeh factory' Nikon 50mm F/1.4D or Nikon 85mm F/1.8D on my Nikon D70. The bokeh was amazing and the picture was always clearly sharp even though I set the aperture wide open at F/1.4 or F/1.8. But on my new Nikon D90 most of my pictures that have been taken with both lenses (with object more than 4 metre away) was not as sharp as the one that had been taken with my previous Nikon D70. Sometimes it back focus or front focus. My two bokeh factory lens is collecting dust now since I have my Nikon D90. I miss my Nikon D70.

  1. My 50mm AF-D F1.4 also back focuses same issue with you but oddly if you use the center focus of the D90 you get tack sharp photo almost 80% of the time.... other focus point is almost spot on if the subject is near but if it around 2.5 meters away I slightly get backfocus problems

  2. Even I have 50mm F/1.4D or Nikon 85mm F/1.8D.

    I have a d90. The results of 50mm f1.4D is useless.... really disappointed.
    I had similar issues with 35mm f1.8G DX. I had to sell it. but the lens worked superbly with D300.

    It is the D90 that fails to AF. it even does not have a AF adjustment like D300s.
