MK III focus issued SOLVED! PERIOD!

Go to last post
Sounds like your dealer doesn't want to deal with defective cameras. ;)

This is going MUCH more slowly than the 1D-II releaes, IMO. And I got my 1D-II's from the same dealer I ordered the 1D-III's from.

It's far from "proof", but the evidence suggests there may be an issue and Canon's trying to limit the number of bodies out there that it may have to fix.

It doesn't explain why the issue described by RG only
occurs in bright lighting and hot weather.

It doesn't explain why RG noticed shifts in focus when
steadily aiming at a stationary subject.

...Not that I have a better explanation...

When did I say that new mkIII owners shouldn't achieve focus anywhere???hello??

all i'm sayin' is that due to the many complex custom settings (some of them totally new even for mkII owners) on AF they achive FOCUS WHEN THEIR CUSTOM SETTINGS SUITS THE SCENE/SITUATION !! as simple as that dude..and pls cut the ironic space shuttle thinggy...people died just because they don't wanna change the thermal plates protection system on the shuttle because it will lead to huge excessive costs , a completely new shuttle to project and build thus suspending all the space program for years etc etc + the old 1 being scraped b4 it's time. America's runnin wars in different parts of the world so the space shuttle is not their top priority at the moment....there you go happy now?? space shuttle problem solved :-)

Take a look at the photographs he had as examples. Bright lights and hot weather...sounds to me like he was shooting summer sports (i.e. rugby, track & field, etc.). The sun is clearly high in the sky in some of them. It sounds like it could just be a coincidence.

Settings you need to change often should not be buried under custom settings. If you have to get into the menu to change custom settings every time you change a lens that would not seem to be great design.

Better to have a switch on the body for 400mm or greater/sunlight/heat.

I know everybody's gonna jump all over me since i'm an
amateur,never had a MkII or III bla bla bla but the solution is
simple as it can be (as always),and most of all comes from Canon
not rich amateurs etc etc so here it goes...just watch this video

IT CLEARLY SAYS : "WE MAKE IT A CONFIGURABLE OPTION. YOU CAN CHOOSE
TO HAVE THE CAMERA FOCUS ON THE 1st SHOT IN BURST MODE AND FROM
THE 2nd ONE ONWARDS THE CAMERA WILL GIVE A PRIORITY TO JUST GET THE
SHOT AND TRY TO GET THE FOCUS" .......i

You provide a valid point! Yes, Canon makes this statement. The 1D-III default shooting conditions are EXACTLY what I want for MY particular shooting style and subject material. I love how the 1D-III works.

However, many hard working pros using the camera for weddings, sports and other venues find that their images are unacceptable comercially because of perceived focus problems - particularily when compared to the previously popular and excellent 1D-IIn.

Does this "surprising failure rate" for existing professionals who are used to the 1D-IIn or 1Ds-II mean they are caused by errors in the focus system or the difficulty of setting up the camera for "normal" shooting.?

Although I can easily duplicate the "focus errors" reported by other hard working pros, it seems to me that Canon is in left field if they totally change how the default camera configuration works and that the working wedding, football, baseball, etc photographers must "learn" how to configure that camera to replicate what the 1D-IIn did "out of the box"

You haven't contributed a damn thing yet. I'll listen to those who own the 1DS3, not want a bees who don't. Have you considered psychotherapy?

or a hot day as the RG article says.

Seems to be a heat related issue as there is a clear performance difference between hot and cold days.
 
White reflects light and heat. Black absorbs it.

In very hot conditions, the body and the lens, particularly a very long lens, would expand at different rates. (I use this physics to get tight lids off jars)

Ironic if it came down to temperature tolerances. It shouldn't though.

A few people, like billymokdad and others, are getting problems with completely static shots.

The issue reported by Rob Galbraith and others takes place with long lenses (400mm or more), in bright conditions, with high temperatures.

It completely puzzles me why people keep posting specimens and "solutions" that take neither of these situations into account, when these situations are the PRECISE problem under discussion.

I've been asking around the pro photography shops here in Hong Kong.

NO ONE seems to know when any more 1DMkIIIs are coming in.

Take it as anecdotal, but it adds a little evidence to what I've already heard about a freeze on distribution.

delivered to my local dealer (Newcastle, Australia) on Friday morning 22nd. The dealer rang Canon Australia on Tuesday for me and they said a shipment had arrived from Japan that morning. So, yes, they are still shipping. My dealer has only received 3 so far. The first "store copy" on the 14th May, the second on the 24th May and mine on the 22nd June - so they are still in very short supply. Mine is still firmware 1.08.
 
I hate to burst your bubble, since you post like you're certain you have this figured out.

But the facts are that many professional nature photographers on Netscape.net have tried all the different settings for focus priority in the custom settings, with no better results than the blurry photos when tracking a moving subject.

I don't know the answer, and while nobody is actually certain that there is a problem, it sure looks like there is. Even Greg Downing posted saying that he was returning his Mark 3 rather than wait while it gets sorted out.

So maybe you're on to something, but the facts known at this time surely suggest otherwise.

Sometimes it's true that a fresh look from the outside is more objective than that from someone actually holding the camera in his hands. But the progression of your posts in this thread suggests to me that "objective" does not describe your train of thought. Maybe you thought you were on to a good clue, but after that, you have spent more time defending your original idea than you have being objective.

That's my 2-cents. Take it for what it's worth.

Why'd you have to go ruin my theory. LOL

I'll just have to add to it now . . the ones you're getting were released over a month ago and took the slow boat to Australia. ;)
 
I had problems previously with a 5D, when it got hot, the focus lights disappeared from the view finder, but I believe it was a physical alignment issue rather than electronic. The III issues appears to be elecrtonic.
