Free Update Will Enable EF Metadata, Line-Level Audio Recording
Canon said a free firmware update for the 4K EOS-1D C DSLR will be available next month. The update will enable EF-mount lens metadata to be stored in recorded video, and will add an option to the current mic input allowing the selection of line-level recording. Compatibility with a wider range of audio sources should make the 1D C a more flexible production camera.
The standard line input level will be -8 dBV with peaks up to +6 dBV, and levels have 64 steps of adjustability.
Also enabled with the new update will be peripheral illumination and chromatic aberration correction for most EF-mount Cinema lenses. Peripheral illumination will remove the effects of vignetting (dark corners) and other uneven brightness levels that owe to lens characteristics, and chromatic aberration correction reduces color fringing and bleeding. However, Canon said the high-end CN-E30–300mm T2.95-3.7 L S and CN-E14.5–60mm T2.6 L S will not be compatible with the new updates.
The update won't cost anything, but it will require that your camera be sent to a Canon Factory Service Center. See more details at the link below.
