Sony RX10 II: Completely new where you can't see it (pictures)
The only significant design difference is the mode dial.

I've been reviewing hardware and software, devising testing methodology and handed out buying advice for what seems like forever; I'm currently absorbed by computers and gaming hardware, but previously spent many years concentrating on cameras. I've also volunteered with a cat rescue for over 15 years doing adoptions, designing marketing materials, managing volunteers and, of course, photographing cats.
The RX10 II is rated at 14 frames per second for continuous shooting, up from 10fps on the older model. DMF stands for "direct manual focus," Sony's manually-fine-tune-after-autofocus mode.
