I noticed now and then that there were a few K10D PEF files that neither Lightroom nor DNG Converter could read. Pentax Photo Browser always reads them and can write them out as DNG files. Once that's done, both LR and DNG Converter can read them.
Today I did a bunch of product shots and had the camera pointed face down on a copy stand. 3/4 of the PEFs were unreadable by Lightroom, but all were just fine to open and output as DNGs with Pentax Browser. As I look through my libraries, all the PEF files that fail were made with the camera pointed down. No DNG file made by the camera has ever been unreadable by Lightroom or Camera Raw... Seems to me that there must be something funky about the PEF file created when the orientation sensor is in an ambiguous position... ??
