Z 6III coverage and implementation

Part of the Nikon Z 6III reference. Read the overview for firmware, survey scope and evidence levels.

Field reports and fixes

Report	Finding	Fix	Evidence
#276 Codec picker	The body advertises H.265 at 8-bit (0x0001_0800) and 10-bit (0x0001_0A00). Collapsing both into one “H.265” row pinned the picker to the first, so returning to H.265 landed on 8-bit.	Identity is the raw value. One H.265 row carries an 8-bit/10-bit pair, and each writes its own advertised value.	Synthetic (Z 6III-shaped fake)
#274 Release modes	The fallback drive list was sorted by raw value, which puts CH before CL. The Z 6III order is Single, CL, CH, CH+.	Advertised set, release order; Self-timer and Quick removed from the drum.	Synthetic
#274 Focus labels	AF area 0x8033 read “Subject”, which looked like subject detection in the next tab.	Labelled “Subject tracking”.	Code
#272 Focus dial	A focus-by-wire drive kept the command channel for tens of seconds. The body answered busy to ChangeAfArea, so the dial and tap-to-focus were dead until a half-press.	Wall-clock channel budget; AfDriveCancel when the readiness poll ceiling is reached; an AF tap pre-empts the drive.	Observed report; synthetic budget tests
#257 Camera authority	After a session with a Z5II on shutter speed, a Z 6III set to shutter angle came back on speed.	The camera is authoritative: connecting reads MovieShutterMode, never writes the previous body’s mode.	Synthetic wire test with two fakes

Focus-drive and release details are on the ZR controls page; they apply to the Z 6III through the same operations.

Remaining qualification

Area	Remaining
Connection	Owner retest of USB-C and camera access point after the product-name fix
Android USB	Reconnect after a pending live view without the dead-write error
Pickers	The H.265 bit-depth pair and release order against the body’s live descriptors
Focus	Focus dial and tap-to-focus after a long pull on a native STM lens
Everything else	Formats, exposure, audio and media on a Z 6III have no dedicated evidence; treat ZR findings as unverified here
