First things first. Potential D800 folk want to know what the status of that camera is. At this point I'm 100% certain that NikonUSA knows how to get a body to where it should be if it does have misaligned AF sensor information. The second procedure deployment seems to have corrected the problem I saw with the first (all bodies were coming out with what was effectively a center of +10 AF Fine Tune).
Second, I've now seen enough just delivered D800's without the left sensor problem that I'll probably revise my D800 review back to Recommended later this week (applies to US serial numbers 3050000 and higher). This has taken me longer than expected for a simple reason: people are doing more tests and seeing more things, but I then have to figure out if they're performed the tests right and what it is they're seeing. A modest AF Fine Tune miss is not the same as the left sensor focus problem, and very common with all bodies. Moreover, the former is user correctable and the latter is not.
Update: after being challenged on this, I went back and carefully looked at my data and notes. I'm not sure where the extra 5 came in; probably a typo I didn't catch while updating the site while traveling. Trying to figure out an exact number from anecdotal data is not simple. I've seen many reports of problems with "new" bodies still in the 304xxxx numbers, and none in the 305xxxx numbers. Now that everyone's checking cameras, I'm also seeing "bad focus" reports that are clearly not the left sensor alignment problem.
Which brings me to some news: Michael Tapes, the man behind LensAlign, is introducing a new software product on Wednesday called FocusTune. This US$30 (intro price; US$20 for current LensAlign owners) program helps automate the process of getting your camera's AF Fine Tune settings right. The software can be used with or without LensAlign (you get some additional data this way, and as the name implies, it's very quick and easy to get correct test/camera alignment with the physical tool, whereas it's not always so easy with just a flat chart and software).
The FocusTune software works on both Macs and Windows; it doesn't use tethering like FoCal, but it's also not linked to specific camera serial numbers like FoCal. The reports generated by FocusTune are straightforward and easy to interpret. It can be used with any Nikon DSLR that supports AF Fine Tune (currently: D7000, D300, D300s, D3, D3s, D3x, D4, D600, D700, D800).
Given how many folk are testing their new D800's to find out if it has a problem and discovering that it could use some tender loving AF Fine Tune, FocusTune seems like an appropriate tool for the problem. Details can be obtained here.
