If yur camera is listed here OS X Lion: Supported digital camera RAW formats it is supported.
The list for Mountain Lion appears to be the same. It is possible that the camera will be supported in a future update but there is no way to know for certain.
The Aperture tech specs list your camera as supported by "*** Requires Aperture 3.4 or later" - see the footnote.
So you should be fine with Aperture 3.4.3.
