As a happy owner of a new D800, I thought it was a good idea to check if some of my lenses needed some adjustments of the auto-focus.

As I didn't want to spend a lot of money on extra gadgets or software, I downloaded the usual test charts available on the web but I was not really satisfied about how they looked and allowed me to gauge the results.

Therefore, I thought about the process and came up with the method I describe on my blog:

The idea is:

1) make sure you are analyzing the result at exactly the place where the camera is trying to achieve focus, and,

2) use a chart that makes it easy to visually decide if you have proper focus or not.

Please try it out and let me know what you think

On my D800 and with the lenses I have, I am very happy about the results...
