Speedlites, Printers, Accessories / Re: Can we all send a complaint to Canon to fix the AF-Assist focusing on the 5D3?« on: December 12, 2012, 01:04:41 PM »
I am a wedding photographer and have shot 25 weddings and receptions this year with the 5D3 and 600ex. I started a thread about this issue about a month ago and I finally sent my camera in to Canon to get the shutter replaced and the light leak issue resolved and I specifically complained about it the AF assist beam. When they sent it back they mentioned they made some "electrical adjustments" to the shutter and AF. They never acknowledged there was a problem or said that they did anything to fix it. I haven't shot a wedding since then so I haven't gotten a chance to really test it out yet but I did some quick tests and sometimes there appears to be some improvement. Other times it still seems slow. I don't think there is a way to know until I shoot a wedding again. I do think it is interesting they didn't even acknowledge there was a problem and always say it is the first they have heard of the issue.
this is expected and I doubt we will see any traction on this topic until and unless someone gives a very specific test case to Canon that can be reproducable, and insists that Canon acknowlege that one camera performs better than another. As long as there is one single 5D3 that you send in, they will always obfuscate the issue and say all is performing to specifications. they can say that because they will run some standard set of diagnostics, performed by technicians who follow procedure, and the diagnostic says "all specifications are met".
instead, someone needs to send in a 5D3 and a 6D, describe in great detail how to reproduce the problem, and then insist on an explanation. I realize thats a tall order (nobody wants to part with two camera bodies for two weeks...) but it might be necessary.
Even if, at some level within the organization, Canon recognizes the problem, it will likely be addressed silently with new production hardware and/or firmware fix that will not be documented. just my opinion
