Interesting article. I tried to find the front/back focus arrows in my D300s but there doesn't seem to be any. No mention of this in the manual either.

Anyone else try this?

The arrows are only on some Nikon DSLRs, mostly the higher end ones. Unfortunately the D300 and I assume the D300s did not get the useful feature.

I played around with this procedure a bit. It does seem to work, at least with the D7000 and couple of lenses I tried it on. It confirms the AF settings I had previously determined. But the range of AF Tune values over which the in-focus dot was lit was quite broad, so for body/lens combinations that require a large offset, you may reach the end of the available range before the dot goes out. Thus, while it's a useful and easy technique to use as a starting point, I'm not sure it fully replaces the more exacting techniques.

Thanks for posting this, it looks quite useful and easier than comparing a bunch of 100% images on a computer.

My D4 just came back from a minor warranty repair at Nikon USA Melville. Nikon adjusted the AF operation even though I didn't think I had any AF problem and hadn't asked them to check it. This means my previous AF fine tune settings probably are incorrect. I need to redo the AF fine tune. I'll try this method to see how it works and do a Lens Align after adjusting.
