I'm finding that a lot of my lenses seem to need nearly the maximum AF fine-tuning that I can accomplish in camera. I just read on a blog that if the AF fine-tune needed is more than +/- 10, the author sends the lens back with a note saying as such. He indicated that he's seeing more such issues with Nikkor lenses than he used to. I wish I had read that before I had purchased four of the lenses I now own.
Who installed your screen, and what brand is it? Would you recommend it to someone buying it now, and will AF still work with it installed?

The focusing screen I have is one I got from
focusingscreen.com. They have expanded their Nikon inventory considerably since I got mine. It is actually a modified Canon microprism/ground glass screen. It took me maybe 5 minutes to install mine with the tools that were provided. Before you get one, make sure your camera can accommodate interchangeable screens. Although I cannot say for sure as I have no autofocus lenses, I see no reason whatsoever why they should not work with autofocus lenses. The one I have is brighter than the original D700 screen.
When it comes to manual focusing, the screens in modern DSLR's
SUCK. I say that because they are not nearly discriminating enough for
critical manual focus be because they are simply not
designed for it.
