I have some fabulously sharp shots already with the lens, but I also have a fair few like the following where the correct AF points are lit, but the subject under them is not in focus. I am using focus priority so I would have though this wouldn't happen, or at least not so often. I think the bird provides far more contrast for the AF system than the snow does.
Too little light maybe? At least I am getting the correct AF points lit.

This is irrefutable.

Why?

Cos I finally gave in and bought a new 100-400 today.

[...]

Your topic is misleading but ... I understand (hopefully) what you meant: Just the moment you gave up waiting on a new 100-400 and bought a version I Canon will release the Mark II.

I was in the same situation one year ago and bought a 5.6 400 waiting for the release of a Mark II version of that lens with IS but ... it is still not available and will cost (my estimate) roughly 3000 EUR / $ and the same will happen with the 100-400.

I try to learn to be happy with what I have. If I remember the days I made slides I had to wait 2 weeks for development (Kodachrome) and 36 exposures where enough for 2 weeks - digital has simplified the TECHNICAL PROCESS of photographing dramatically! Quality of APS-C is near FF with slide films if not better ...

Enjoy what you have - nearly all the lenses are good enough for great photographs ...
Its the only way to go. Cheers

congrats, but you need to reconsider the subject of your post, It's misleading a lot of hoping souls!  ;)
plus 1!
I know, and I am sorry, and I apologise to everyone who I mislead.   :-[

But I also hope you all appreciate the personal sacrifice on my part so that you guys all at last get the updated 100-400 from Canon that we really want!

Everyone except me that is.

Actually I just sold my 70-200 EF IS F4 lens via ebay, after canon rebate and ebay charges I only lost about
120$ so should Canon bring out a new 100-400 that is so much better than this one, the financial loss will probably not be huge.

But I now have the Lens for spring and I hope it will serve me well.

Thanks for the infos about the flash, I guess that can offset the fact that this is not a straight F4 or F2.8 to a certain extent.
Cheers Brian

And this one was about 8 meters away.

This is irrefutable.

Why?

Cos I finally gave in and bought a new 100-400 today. I had tried one that belongs to a
colleague, and wasn't too happy with it. But my new copy works pretty well.
Pretty poor light here today but still happy with the results at ISO4000+ on my
5D MK3.

Shot at about 4 meters away in sub-zero temps (making me shiver), no noise reduction

And here are the 5 photos I submitted for judging.
I nearly said "Great photographer, but lousy at maths", glad I didn't now! :-\

Lenses / Re: 100-400L Version II ain't comin' either!

Native 400 in the zoom is better in my hands than the 70-200II+ 2xIII.

I find with the extender, the image clearly softens and the contrast goes down... Of course it can be bumped up in post but depends on what is acceptable to you. The images can be more than acceptable to some...
I guess that my main worry would be what effect it has on AF in my 5DIII. Of course the straight 400 5.6 is also an alternative. Decisions, decisions.
Thanks for all your thoughts.

I think they can definitely improve the optics and AF speed of the existing model.  I used to own a copy but found the 70-200/2.8 II + 2x III was close enough in performance to make it unnecessary to carry around two large lenses. 
I have the 70-200/2.8 II and its not long enough, so I was looking at the 100-400. I'll be keeping the 70-200 anyway. Your suggestion also came up as a possibility.
I'm a pure amateur so a new 100-400 may be too expensive for me anyway.  Do you still stick to your guns concerning the quality using the 2xIII? Certainly price, space, weight makes it very attractive as a solution.

Abstract / Re: Abstract Interiors

I was looking for a spot to place this so I created a new subject called Abstract Interiors.
This is the inside of a Hotel in Cork City Ireland shot with a Fisheye Lens.
It reminded me of something out of a Stanley Kubrick movie.

Would love to get some comments or some other abstract interiors.

Stairs!

Hi,
well I had far better results yesterday, despite pretty poor light. Still had a few shots I couldn't explain, 4 focus points on a slow moving car, but the car itself completely out of focus. But I even did get a shot of a flying duck in focus in pretty bad light, taken a bit by surprise too. Using 61 point auto-selection.
Never had the points on a bird in a sutuation like that up till now.
Cheers Brian

And built this out of it. I guess my next Lens will be something with a 400 in it. 200mm doesn't go a long way.
Cheers Brian

You can go to usa.canon.com and download the English version of the manual for free.

it seems like you forgot an IMPORTANT THING

pls review your manual at page 73 and page 77

61 point automatic selection AF both in A+ and AI Servo Modes

dont worry, there's nothing wrong with your 5D3, just wrong user settings. :)

we all experience it - one way or the other.
That was a very good suggestion. Now I can immediately find the things you all were talking about in the manual. Still no real sucess though. I hope to get out tomorrow with the camera and try some more.
Cheers Brian

Hi bjd,
   Yes, you are describing exactly what I expect to see - the AF "HUD" showing in real-time what it has locked on to, even though it has shifted.

    I tried a few variations on the interpretation of "61-point" before changing the AF display to "constant 61 point" (changing the available points through the reticle/M.Fn didn't help).

    Then I tried turning off point expansion (above/below/left/right and the 8 points around) and voila!

    When I do this, it DOES indeed track!  AF5 Mode 1,2 and 4 don't but mode 3 does :)

     There must be a reason why it only works in this one combination of modes (but still tracks invisibly).  Given enough time, that reason may become apparent.

Summary:   
     it seems that in order for this to work, the AF mode needs to be All 61 points (ie, all the points in the VF and the curved brackets as well) AND set to single point (no expansion) AND the AF5 display mode set to ALL (Constant) or SELECTED (Constant)

Thanks, bjd and J.R. -- mission accomplished :)
FWIW,
I installed the Exif Meta LR plugin today. It allows you to display a lot of EXIF data, e.g how many AF points were in Focus, how many selected, and loads of other stuff. I'm still fighting with configuration of the plugin, but that info may answer some of your (and my) questions.

Cheers
