This is an update on Pentax K10D RAW support. My K10D arrived today and it writes either PEF or DNG RAW files. After digging around a whole bunch, I determined that the K10D seems to use the "mosaic" type of DNG file that Aperture does support but this type requires support for that camera already in Mac OS X. It appears that Apple has chosen not to use the "universal" support for DNG that can be used. ACR supports DNG files from the K10D just fine but is not optimized for the camera yet.
So, in the end. "Full" support for DNG doesn't exist without supporting cameras individually at least when it comes to Aperture. Therefore, we have to wait for Apple to issue an update that adds K100D and K10D PEF support (which also provides DNG support for the K10D). I wish Apple would hurry up already!!
