How long have you owned it, Stephen? It's the inconsistency factor that is so befuddling to me; sometimes it coincides with when I'm shooting AI Servo, sometimes not. Perhaps the intersections of your subsets have been aligned by your good karma...

Jeff, it is not how long I have owned the camera, it is how much and how did I used my camera. Yes, I only had the camera since mid August but I have already shot more than 6,000 shots, mostly were for testing. I have been shooting three solid days of birds. After another 2,000 + shots, I still have not encountered the type of inconsistency problem some of you have.

Even if I owned the camera only for one month, I may have posted more examples and images from my new camera than most of FMers who have owned the camera for months. Although I came in the game later than a lot of you, I have been reading for two months regardign the spec and problem people have. Plus, I have been shooting with my Mk2 for three years for the same type of subjects. I do have a shorter and more gentle learning curve, partly thank you for you guys posting the information regarding the camera.

I do feel for you guys who are having problem with the cameras. But, I do not think it is right to imply and speculate that ALL the MK3 are defective due to design problem, and over 50% of the users have no idea what they are doing.

May be it is my luck, or may be I have no idea what I am looking for. I do feel better than I am not the only one who claims that the camera works as advertised

. I think we just have to agree to disagree.

Steve, I mentioned something similar to your comments in another thread. The fact that there seems to be quite a few MkIII's with no AF problems one would have to assume that something within the camera besides software is the problem. There is the possibility that some have a defective AF module that is affected by heat or bright light and the problem can be intermitent depending on circumstances. My opinion is that there may have to be a recall in order to solve the problem. I plan on waiting a while before purchasing one. Just broke the on/off switch for the vertical shutter release on my MkII so it's off to Canon but so far I'm impressed with my new 40D

What if the DsIII has the same known focus issues as the DIII. Does it employ the same focus system?? Who would be game to drop serious coin on this new DsIII. Even if 50%+ of new DIII owners are happy would you gamble on this body at the price?

I know I wouldn't.

The AF on the 1Ds was the same as that on the 1D, the AF on the 1Ds2 was the same as that on the 1D2, there was no 1Ds2N, but it's almost a sure thing that the 1Ds3 will have an identical AF system to the 1D3.

Which is very scary indeed.

Regardless of what's causing the MkIII performance problems, I think at present there is an unacceptably high probability that a buyer would end up with a poorly focusing MkIII.
Naturally, I ain't buying it. In fact, even if it performed as specified/implied by Canon, I'd have a difficulty dishing out $4.5k for it, compared to perfectly viable/mint MkIIN's at around $3k.
Yup, Canon hit the camera performance-price point at which I am able to curb my techno-novelty thirst easily.

Unless Canon come clean with the MkIII AF story, I don't see their 1DsMkIII selling like hot cakes either.

It was being claimed by someone at dpreview that the 1Ds III has an updated AF module that does not suffer temperature related misbehaviour.

I remembered someone came from Calgary said that the 40D and the 1Ds3 has a new AF system that is different from 1D3 and its not temperature sensitive.

The 40D uses a completely new AF system not seen before in any Canon cameras, I can't comment on that.

Historically, the 1Ds series has used the same AF system as its partner 1D.

The 1Ds3 almost certainly uses the same AF system as the 1D3 for the simple reason that if Canon have found that they need to improve temperature tolerances for their 1-series AF to work, why haven't they announced that they have found the problem with the 1D3 and taken steps to make it right for all those who have already bought the camera?

Consider what you would do if you were in Canon's position? You certainly wouldn't want to owe up to 1/2 of the problem and/or announce a fix or exchange policy that didn't eliminate the entire problem (and the few more that might emerge after more field use?).

Jeff my main AF issues has been in bright sunlight. I had a signficant number of out of focus shots at Big Sur when shooting the rocky creek bridge in AF Single shot mode. I found AF tracking of mountain goats at Glacier was fine when i was shooting them in shade. However when they were out in the sun, same issue. It just seems that the camera is not holding focus under bright conditions.

I also read that both the 1DsIII and the 40D do have some different hardware then the 1DIII. So a hardware fix may be needed, althought so far from everything i've read it looks like canon is just trying to deal with the issue through firmware updates.

I see even after half a day it is still showing in stock. I think there is a message for Canon in there. I can remember reports of 120+ cameras selling out in 30-mins. There are tons of folks wanting a new MkIII but are hesitant to risk $4500 on a dud.

Buying one now is like shooting craps, it's a gamble. You roll the dice you take what you get. I think I'll wait till the Mk3N or when Canon annouces a fix.

I think I would wait even longer than that so that any of the old ones floating around have been repaired or returned to Canon.

I had a great copy of the MKIII but I know of many pros that have had several bad copies. They are not strangers to the 1 series and compared to mine they were definitely defective so I think the jury is still out as to whether the AF problem is truly blown out of proportion.

Perhaps many have not read Ron Gailbraith's original, and now updated, article on the EOS-1D Mk. III it's at the link below.

http://www.robgalbraith.com/bins/multi_page.asp?cid=7-8740-9068

Mr. Gailbraith's article does seem credible.

I would flippin' well hope that the 40D has different AF hardware from the 1 series - otherwise why is the 1D3 more than three times the price of the 40D?

Seriously though, the 40D and the 1D3 share almost nothing from their AF system. The 1D3 and the 1Ds3 - that's a different story.

Studio 58,

I had the same one shot autofoucus issue as shown here. Also using the same lens......... Sent the camera to Canon.
They said " electrical adjustments to autofocus system, installed new firmware" .

The one shot autofocus works fine now. Not so sure about A1 servo..

That one shot seems badly OoF.
Yet, I think we all get occasional "inexplicable" OoF shots, even with best gear and best practices used, on the type of targets we habitually/routinely shoot . Therefore, the key consideration ought to be a change in frequency/persistency of misfocused shots......based on a fairly large number of images.
