Q: raw photos no longer importing into iphoto

You say "no longer importing" - What has changed since they did import? What version of iPhoto and of the OS do you have?

Here is the list of currently supported RAW - It looks lie you camera is not yet supported

OS X Yosemite: Supported digital camera RAW formats - Apple Support

No one know when or if Apple will update support for any camera - you can send them feedback  - iPhoto menu ==> provide iPhoto feedback

Other than that you will need to use there RAW conversion while you wait for Apple
