Canon has released the firmware 18.104.22.168 update for the EOS C70 Cinema Camera. The update addresses issues announced in a recent service advisory pertaining to the possibility that the C70 and the Canon R5C full-frame mirrorless camera could become inoperable after repeated stopping and starting under certain conditions.
The phenomenon that is being referenced here has been reported by users who experienced an error in the Canon XF605 UHD 4K HDR Pro Camcorder, which experienced a “fan error” when stopping and starting recording while the constant recording option is set.
Canon says that the phenomenon does not occur if the constant recording function is not set or when not recording in MP4, which is the only mode that the constant recording can be enabled.
Previously, the Canon C70 received an update that enabled it to record 12-bit RAW at up to 6- frames per second. That update also added the ability to perform both stop motion and time-lapses, as well as adding support for a .71x mount adapter. EOS Standard and Neutral Picture profiles were also added at that time.
The smaller form cinema camera is capable of capturing video in a variety of modes including Cinema RAW light ST at up to 30fps, Cinema Raw LT at up to 60 fps when shooting in Super 35 mode with no crop, as well as those modes, and Cinema RAW HQ in Super16 mode.
The EOS C70 can also record simultaneous 12-bit Cinema Raw light and 4:2:0 8-bit proxies by utilizing the available dual card slot.
By contrast, the Canon R5C recently made headlines when Netflix rejected certification for the mirrorless camera, which many analysts speculated was due to the Canon R5C lacking C-Log 2 as a recording option.
Though Canon has stated it won’t be seeking to gain Netflix’s blessing by addressing whatever shortcomings prompted the rejection, it’s hard to believe that the company wouldn’t add the option since a firmware update is needed anyway.
Since the C70 and R5C are equipped with many of the same functions, Canon opted for caution to apply the fix to their respective firmware in order to avoid the error.
Canon reports that the phenomenon could only be triggered when firmware version 1.3.1 or earlier for the EOS C70, or version 22.214.171.124 or earlier for the EOS R5C.
The firmware fix is known as version 126.96.36.199 for the EOS C7, and it can be downloaded at the Canon C70 support site. The XF605 update, known as Version 188.8.131.52, is available on the Canon XF605 website.
Canon has yet to update the firmware for the Canon R5C Mirrorless camera, therefore that fix remains forthcoming. When it does, however, the Canon R5C support site is referenced here.
