Alistair,

Thanks for the reply and your experience with it.
A) I will buy one in the end of this year
B) I fly a lot between Bangkok and Sweden so that would not be any problem. But Canon Sweden will repair it even if it doesn't have world wide warranty like the lenses. As a service for CPS members.
And Canon Thailands Bangkok Service Center has the best service so I wouldn't worry as a CPS member when I get there. They never even check the warranty after looking at the CPS card. They also repair used equipment without warranty for free. And lend me 1 series cameras as long a I need them. And my CPS membership is only for Europe so they don't have to do anything if they don't like.

Hi Henry,

1. This is the first time that I have seen a lot of people buying an expensive Canon equipment that they say have a fault, but they don't really try to return it. That's why I belive this thread is very strange compared to all other similar threads about faulty equipment.

2 The same people who don't have returned their cameras or tried to return it. They are of course angry at Canon because they haven't been saying anything or coming with a fix for their cameras.

3. But all those people also say "no problem that I haven't return it because I will do that when Canon have their hardware or software fix for it.

4. How can they be sure any fix is coming ? nothing has been done for months up to now. And then after waiting they will be sitting with their faulty cameras without any warranty left............

Your point is very well taken. Personally, my camera will be going to Canon for repair as soon as 1.) Canon says they have a fix or 2.) as soon as the fall foliage season ends. If it isn't fixed, it will go back. If it still isn't fixed it will go back again. If a fix or replacement doesn't come along before the warranty expires it will probably end up in the hands of a lawyer as part of a class action suit as I expect that a lot of people will have lost their patience by then and I'll be shooting with a new Nikon.

Lars
I'm a CPS member in Canada, I had to send my body in once already, then again with the lenses and at this point I had to pay $58 cnd for each lens just so they could let me know that they are "in spec". (I know as they all work perfectly on my 5D's)
Nothing changed so I contacted them agian and I was TOLD not to bring the body back till further notice.
In the mean time it's been over 2 months and my dealer will not be able to provide me with a replacement or refund, it's between me and Canon!
so like everyone I am waiting to see what 1.1.1 will do.
I'm no longer actively using my mark 3 anymore.
I am SERIOUSLY disappointed in the camera and Canon!
and feel that my patience is running low!

The return period is one year if the camera has any fault. Good luck with your camera or the replacement.

My vendor is 2 weeks less if you are a "pro" for all the use. It took me about 45 days. 3 weeks I was in Denmark and Sweden covering soccer and then came back and had some other tournaments I tried it at changing this and that and finally figuring it just was not working. The store sent it in to be "repaired" and all they did was clean and new firmware. It did not change it. They had to get canon to give the ok to swap it out. So far I am seeing the same thing with the new body.

For the record, I get stellar results with my 24-105 in both servo and single shot with my Mark III.

Sorry you are having difficulty. I (as everyone else) are in hopes Canon does SOMETHING to acknowledge the obvious problem many are having AND SOON.

I just added a 300 F2.8 IS the other day, but have not had the opportunity to test it out (other than a wedding in a balcony on tripod...

) I hope to get a chance very soon.

This image is Typical of my results, the girl is not moving and neither am I, This is a crop of a 3/4 shot, just below the waist line!
24-105
ISO 200 , F8.0 at 1/500 sec
single shot, you get couple in focus and a bunch out... when you view one frame after another it's impossible to even try to understand how and why the AF is behaving the way it is as nothing has changed. This particular day it was warm and sunny (as you can see)
Out of the 1700 images I shot that day (fashion look book) with my 5D with the same lens there were 19 out of focus, and that's all my bad, while the mark 3 had about 70% soft images that same day with the same lens, which incidentally went to canon with the Mark 3 and came back with a clean bill of health.
so ya I'm waiting....

Arashm, your M3 is working perfectly. What Canon has not told anyone is that they put in an even more advanced version of their face recognition algorithm on the M3 and it can tell whether the face is male or female. On female faces it then automatically soft focuses them to save time correcting blemishes and lines in PP. Pretty clever and thoughtful of them isn't?

Wow. I probably haven't used my shorter lenses much in the right conditions yet. I'm mostly shooting sports and I sure see it with my faster telephotos in bright sun.

That looks just like the same focus issue results though. I need to do more testing.

Cute model by the way!

It is funny but that is how I describe mine during the soccer pictures I am doing right now. They are just soft I even shot at f/4 cuz I wanted the game and not "test" 2.8 or 3.2. You should see each strand of hair in that shot, something just is not right.

So it's not only long lenses when shooting in AI servo. It's also short lenses. And also when not using AI servo, in single shot

May be a little hard to tell here on this particular image...But the crop is sharp..

Shot at F5.6 with the 24-105 in Cabo San Lucas about 2 weeks ago.. SERVO.. HOT & HUMID. I have a whole sequence.. All are very sharp.

For me personally yes, I shoot a lot in single shot and that's where I see my issue's, the longest lens I own is a 70-200, for the most part results are the same. (unfortunately)
(for what I shoot I rarely use AI Servo)
The first time I took my Mk3 in I took 2 CD's filled with oof/soft samples to Canon;
but I'm told the body is in spec and so are the lenses!
Which is why I'm so frustrated

I must have not shot in the ideal environment/settings to get it to NOT focus, because I just got a mkIII and every single shot was sharp at the motocross track.
I shot only riders coming at me, only aiservo, only NON center focus points, 70-200 2.8 IS lens, f4-f8, bright and hot sunny calif. day.
These pics pretty much suck as far as photos go, composure, but I was just testing it out and trying to use focus points all over the screen.
They are hi res
so tell me why they are all sharp?

You'll probably hear that many bodies are doing fine at smaller apertures and shorter focal lengths. I noticed many of yours were at around 200mm at F6.3 or so..

Obviously, there are people having good luck though. I include myself in that pool of owners. However, until I get a chance to shoot my 300 at F2.8 in servo in hot sunny conditions here in Dallas, I won't be 100% convinced.

On the other hand, I shoot weddings and events mainly and have shot approx. 9300 frames in those environments and have had very satisfactory results with lenses from 17mm - 200mm... Anything that has been soft has typically been user error or just not enough shutter speed/light for the situation.

I will continue to follow this thread...I am very interested in the new firmware as well as Canon admitting there is a problem somewhere. All in all, I am happy with the performance I am getting. Once I start my football/baseball/soccer shoots here very soon at longer focal lengths, I may change my mind. I sure hope not.

I will try some with the 300 2.8 tomm. I hope.
FWIW, this one is from a very new batch of mkIII's, has a build code of august 07'....but then again, maybe I just didnt shoot in ideal 'galbraith' conditions

Not sure if it has been mentioned but there is a rumor going around that there were a high degree of defective focus sensor components in the earlier camera's and that all camera's that will be shipping with firmware 1.1.1 will be fixed....take that for what it's worth...
