Canon pulls latest 5D MkII firmware due to issue
Canon has cautioned on its website that the 2.0.3 firmware update for the EOS 5D Mark II DSLR has audio problems. When users change the manual recording levels for the C1, C2, or C3 modes and Sound Recording is set to Manual, the camera will not record sound along with video if power is turned off manually or automatically after idling. Canon urges 5D Mark II owners who have already downloaded the firmware to mitigate this issue by setting Sound Recording to Auto.
The company also says it is working on new firmware that will get rid of the problem, and has pulled 2.0.3 from its support website. When the new firmware is available, Canon will notify registered owners of the DSLR in question.
Among other changes, the firmware allowed 5D Mark II users to record videos in 1080p24 frame rates to match those of traditional movies. The 1080p30 mode has also been tuned to 29.97 frames per second to stay in sync with NTSC-based TV, and users can also now shoot movies in aperture or shutter priority modes.
