Dan said, "If I'm understanding you correctly, that is not odd or unusual at all. Typically, you must have fully updated software with the newest drivers to open raw files from new cameras like this.
It is actually the norm that early adopter buyers of new release cameras may not be able to open raw files in existing software until new drivers are released."
You are right, Dan. It was the first time I had encountered this. Perhaps others have run into this. However, I find it unacceptable that Fuji released the E5 and did not update Fuji RAW converter to accommodate the camera.
