The latest report on 1D Mark III AF issues

I am seriously looking to upgrade, would like more mpx and dust control thats why.

care to sell your mkIIn?

^^ I see that signature, and that message. That's a high impact statement indeed.

Do you think the problems will go away before a Mark IIIN arrives?

don't know, don't care my mkIII is sold and i have a 40D on the way (that is even a bigger statement if you ask me) and now i am looking for a mkIIn which i had before and NEVER failed me in any way (yes, i learned my lesson about jumping on the latest and greatest)

^^ Even more powerful, IMO, because that's your money talking.

I have no issues with the MKIIN; it will remain for quite a long time. I hope you get one from a reputable person who cared for it well.

BTW, nobody could have known a MKIII would not do better than a MKIIN across-the-board. Canon has a very serious problem, short-term.

I have not purchased yet the Canon EOS1dMKIII, because I'm following since the starting these very interesting posts concerning this new Canon camera and I find it good to wait until the AF issue (I really think there is a problem) becomes definitively solved. Upon waiting for this, my EOS1DMKIIN is performing quite well for my birds in flight pictures.
After reading some posts advising that temperature changes coud be part of the problem and that some cameras seem to be faulty and others have no problems, and bearing in mind that I'm a Senior Electronics Engineer, having worked with many devices that include printed circuits with a lot of solderings, I would only like to suggest the Canon people to look for a 'cold soldering'. When different parts integrating a circuit must be electrically together by means of a soldering, it could happen - if the soldering system employed is not correct - that one or several parts do not become electrically bonded as they must. This problem - if not found in due time - originates the following:
a) Some solderings are good and therefore no problem at all (cameras working OK) or some solderings are not Ok thus producing a 'cold soldering' followed by total or intermitent malfunctioning of the electric/electronic circuit involved (cameras non OK).
b) Temperature changes in such 'cold solderings' produce that the parts to be in contact can be or cannot be in contact depending on the ambient temperature producing thermal dilatations on the materials involved and causing them to do/undo their electrical contact.
It's just a suggestion and if it helps I would be very glad. Excuse my very poor english and regards to everybody there.

Your English is very good, so there is no need to apologize at all.

Interesting take on it, as well. So, do you suspect Canon engineers are working hard to find out why there's a defect?

Yes Sam, there are many good photographers here and that's why I dont think they are wrong in what they say. Something is happening on the AF and off course, if Canon wants to be the leader, they must do something. A different thing is that I'm almost sure that they will tell nothing until they are sure that the real issue has been found and totally repaired.

i with you all the way on the mk3 focus problems .
But why would someone buy YOUR camera after all you have not hidden the AF not working right thing
your one of the last people i would buy a mk3 from
Mines still in a truck on its way back to canon and im sure they will fix it

So there's no chance of me unloading mine, huh?

Rob, i stated that my camera has the AF inconsistency just like i told him that i think that all mkIII has the same issue. besides, just because i am very vocal about Canon's behavior does not mean that my problems are worse or anything like that. as a matter of fact, in the past month alone, i managed to take the best 5 images of my life with the mkIII and i even stated here that my camera has been working amazingly since i understood what i can and can not shoot. if you want, i can post 2 shots that are going to be published soon that were taken with the mkIII and i can also post some AI Servo shots that will show you that once you understand what the camera can and can not do, you will be fine.

like i said, i think that with me it is more of a principal right now combined with the fact that i have simply had enough of this whole thing. i have a new plan for my kit that i feel will work better for me at this point.

The Canon EOS 1Ds Mark III is a disaster of epic proportions. This camera was in development for how many years? And it's been how many months since it was released without being fixed?

When was the last time any SLR from any company was put on the market--especially a very expensive camera--that was so f'd up?

Canon's attitude to the disaster makes the whole thing even worse. It's disgusting. To treat the customers, many of whom have been loyal to the brand for years, and spend a lot to get it, like idiots, is beyond the pale.

Now why couldn't Canon have loaned a prototype to many photographers who shoot many different kinds of situations so this problem would have been discerned years ago?

It's amazing that they had the camera for years, saw nothing, but real-world photographers have it for a day and see its problem.

Too bad Canon's brain trust can't autofocus on brand loyalty.

they did RG found that problem in the preproduction model that they gave him but for some reason, they decided to release the camera without fixing the AF.

If you say Mark III is "disaster of epic proportions" then you must be living in a world without hunger and wars.

AI Servo (note: AI SERVO, NOT AUTO-FOCUS) in Mark III is not perfect. That is the problem. It is not perfect. It was not perfect in Mark II or 10D or D30 either as far as I'm concerned. It works differently to previous models.

Apart from some AI Servo imperfections the camera is wonderful, clearly the best EOS to date.
