SlashGear JPCanon has today announced firmware update and issued another AF patch for the much-controversial EOS 1D Mark III and 1Ds Mark III. The latter is additional to the sub mirror fix released couple years ago, which requires camera to be returned to company’s service location; while the new firmware addresses liveview hiccup, USB communication bug and corrects error codes.
In addition to implement better AF, Canon also published a service notice to the dared “Err 99” occurrence that’s related to mirror operation. A common operation error code that’s designated for all Canon’s DSLR.
The fixes mean the much confused and many “dot” series of current Mark III production would get even more complex. The upside is issues are being addressed but would definitely hurt resell value.
Canon may have slowly losing its professional-ground in DSLR camera’s market, but not in optics department. From the last few years, they have redesigned, and in most cases, introduced a variety of premium L-prime from 800mm 5.6L, 200mm F2.0L IS, 85mm II 1.2L , 50mm II 1.2L to a decently pair of 17mm and 24mm tilt-shirt lens.
