Post here with updates/progress or news related to the MKIII AF Fix.
Post only in the official thread. New threads will be merged.
DO NOT POST HERE about your personal issues with Canon.
Or your theories concerning the existence of a problem.
We have enough posts on that subject now.
Apparently it's still vogue to assume the worst about both photographers and Canon despite the fact that this recent news could very well settle both of the following arguments.
The focus issue is real. Canon's actions clearly establish this as fact.
Debating this reality is only a source of controversy, and needless at this point in time.
Many have created a "damned if you do, damned if you don't" mentality on this,
Currently many feel impatient to have been informed that a fix is in the works prior to the upcoming recall process being ready to be applied.
At the same time (and maybe the same people) many are angry that Canon did not tell us sooner, whether they were ready or able to make a repair or not.
If they tell us early we have to belly ache while waiting, if they wait to tell us when the fix is in, then it's months of belly aching about "no news"
This is a no win situation, and not worth continued discussion.
Keep to the topic of the progress and news related to the AF issue.
The bullets are;
1. There was and is a problem with the MkIII. This is not longer a debate, it is fact.
2. Most of the released units to date may be effected.
3. Canon will be implementing a process to repair the MkIII
I am confident that the time taken to get to the route of this matter was well spent, and we will see a very real very functional fix.
Please do not speculate to the contrary of any of the above, and most importantly, don't do so in a way that assumes the worst of our fellow members. It's insulting and flame baiting.
the time for flaming over this subject has passed.
