Where the Dp2 just absolutely falls down

On the last night that my brother Paul and his wife Valerie were in town, they sold a copy of their print, America the Beautiful, to my boss/advisor/mentor, Daniel V. Daniel wanted a picture taken with them, and so I tried with the Dp2. This was the result:

Focus was off, and the thing just couldn't figure it out. I can only ask people to sit still for so long, and the back LCD was just painfully useless for focus finding in the relatively low light of my living room.

This was the result using the Nikon d300, 17-55 f/2.8 lens, and sb900 flash:

So, when compared to ~$3k of photography gear that I use to shoot weddings, the Dp2 is just not quite there yet. It's also one quarter the price.
