Potter is correct. The shooting of tiny slanted targets is a one way ticket to the funny farm. Don't go where so many have slid down the slippery slope into terminal tweakery. This is a consumer camera with a good basic lens, not an artificial intelligence machine.

Agreed but, note what was indicated

" Walk back to what you'd think is a normal shooting distance for the lens you want to check. "

I've gone out and given it a go...it really is a quick and easy way to get a feel for if more focus investigation is required. Distance is large, light is usually good, and lock-on has been easy. Just a quick check...not a method to a final AF tune.

Print out the test chart here:

and tape it to the fridge and put the camera on a tripod with remote, using autofocus. Compare manually focused with magnified live view to autofocus at 200% in ViewNX. Try it handheld with a high enough shutter speed. If the camera passes this test, then go out and take photos, lots of them. If the lens isn't consistent, then get a better one.

AGREED!!!
