The camera is a Sony ILCE-7R (a7r). If that is not in your database, it should be. The metadata in the jpegs includes the ResolutionUnit, FocalPlaneXResolution and FocalPlaneYResolution tags as well as Focal Length; which is sufficient to determine the focal length in pixels. And is in fact the preferred way to do that, when present, since the stated 35mm equivalent focal length is often wrong (I speak as a developer of photo software). If Photosynth does not know how to use those tags, you should fix that. Meanwhile, I shall try again with 35mm equiv.
