Canon Japan: New EOS firmware By
Michael R. Tomkins, The Imaging Resource (Wednesday, March 29, 2006 - 14:51 EST)Several of Canon's EOS-series digital SLRs have today received firmware updates from the headquarters of Canon Inc. in Japan.
Equivalent updates have yet to appear on Canon USA's website, but full details and the update files are available in English on Canon Japan's BeBit site. The updates are:
Fixes a problem where images have very low saturation when using the Standard, Clear, or Twilight picture styles coupled with a color density of +4.
Fixes a problem where the shutter release won't function when using the EF 85mm F1.2L lens and the Speedlite 580EX flash. (Cameras with a serial number containing a 1 in the fifth digit, eg. XXXX1XXXXX, will apparently need to be returned to a Service Center to fix this problem, however).
