Production Leica S2

Well, support for the insane Leica S2 maker notes was finally added in the version of ExifTool that was released a few days ago. Adding this support was as painful as I had anticipated. As it turns out, images from the production model have all the same problems of the pre-production samples. The question about the funny 0x800 offset is explained by the fact that a different offset base is used for one maker note entry (coupled with lots of unnecessary padding to keep the value at a constant offset). Anyone who understands the TIFF IFD structure will realize how stupid this is -- one may draw their own conclusions about the level of understanding by Leica engineers.
