But my guess is that only a small percentage of people is upgrading its camera firmware. If distribution and sales channel is slow, if inventory doesn’t receive the upgrade, the old firmware will continue growing in installed based for many months until new one first appears, then becomes significant.įirmware upgrade is also possible on older cameras. But it can take a few months until those cameras get into customers hands. When a new firmware is released, all new cameras are manufactured with it. So I decided to dig into our repair history and figure out whether FW1.2.5 has changed anything over the last 6 months.įirst, I notice that after FW1.2.5 release, our Canon repairs drop by 15%, then they start growing again, but at a slower pace than before.
“Rare cases”, “specific CF cards”, look like words forced by PR or Marketing department, and in my opinion, try to masquerade the fact that Canon has only partially solved the problem (or the problems) and that you should not be surprised if failures keep occurring… “Fixed a rare phenomenon in which there were rare cases where movie files taken could not be opened when repeatedly shooting movies with specific CF cards.” In April 2011, Canon has released a new firmware, FW1.2.5, for Canon 7D.Īccording to Canon, Firmware 1.2.5 should eradicate corrupt movies: Here we focus on top Canon-specific failure mode: corrupt file due to firmware bug or system limitation). (There are other failure modes found in Canon EOS cameras, like use of low performance CF cards, accidental deletion, battery issue … but those are the “usual suspects” that we find in all cameras. In any case, this is something that Canon can only hope to solve through a firmware upgrade - or - a new camera design. This smells like a firmware bug or system limitation. It’s as if the camera had stopped working in the middle of the recording, or could not finish its job of adding the index just after recording ends.
