Vendor documents describe FreeD D1 as carrying camera ID, pan/tilt/roll, X/Y/Z, zoom and focus plus a 16-bit spare field, with no lens-distortion data (producer citations; curator confirmed the spare-field and zero-position usage in the Panasonic manual).

Vendor documents describe FreeD D1 as carrying camera ID, pan/tilt/roll, X/Y/Z, zoom and focus plus a 16-bit spare field, with no lens-distortion data (producer citations; curator confirmed the spare-field and zero-position usage in the Panasonic manual). Curator qualifications: Use one wording for bytes 26-27 (per C2-B85-AUDIT4): 'two bytes after focus, named spare/user-defined in some documents and reserved in others; some vendors put iris there'. Epic, TouchDesigner, Aximmetry, Ventuz and Factory Optic pages (S6-S9, S12) not reinspected by curator. Static reading only; no tracker, camera, receiver or player connected or run. Limitations: Vendor docs only. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
