Agree with this Larry. It's called HDR because it uses the HDR approach of multiple images at different exposures. But "multiple" in this case is only 2, so it's usefulness is limited. If you have a difficult contrast range it should give you a somewhat better result but is no substitute for more exposures where 2 doesn't cover the exposure range of the scene.

Agree with this also. Bracketing without the added mirror slaps would be desirable. I often use manual focus anyway for HDR brackets. I also wanted bracket increments of greater than 1 stop available. I was disappointed when I saw that Nikon still limits brackets to a one stop difference. Often times one stop over/under doesn't cover the range and 2 stops over/under would work fine. Instead I have to do five or more one stop increments to get to the ends of the range.
