I wonder if iPhoto supports the new Sony DSC-RX100 II camera.

It's the system that supports the RAW formats. So if Aperture doesn't support it neither will iPhoto.

You'll have to wait until a new Digital Camera RAW Compatibility Update is issued by Apple for the camera.

I'm having trouble with this camera...I'm using the AVCHD setting and importing into iPhoto which is seamless. The issue is when I go to watch the videos they are choppy. Has anyone else had this problem? Do I have to: 1. change the recording format to mp4 2. only import these files into iMovie and not iPhoto? Any help would be much appreciated. Thank you.
