Canon released new firmware for the EOS 50D late yesterday.
According to Canon's website, this firmware update (Version 1.0.3) incorporates the following fixes:
- Corrects a phenomenon in which an image becomes overexposed when C.Fn.II-3 Highlight tone priority is set to "1" together with other camera settings. (This correction has already been incorporated in the Version 1.0.2 and later firmware.)
- Corrects a rare phenomenon in which "busy" blinks on the camera's display panel and the shutter cannot be released due to the timing of battery installation.
- Corrects a rare phenomenon in which "Err 99" appears on the camera's display panel and LCD monitor and the shutter cannot be released due to the timing of pressing the shutter button.
Firmware Version 1.0.3 is for cameras with firmware up to Version 1.0.2. If the camera's firmware is already Version 1.0.3, it is not necessary to update the firmware.
