I've named it Ben - after my third Son. :)

My apologies to Michael …
(Sung to the tune of "Ben" - Michael Jackson - 1972)


Ben, the two of us need look no more
We both know what I've been searching for
With a new rig hangin on my strap
I'll never shoot more crap
And you my friend will see
You'll sense the “pro” in me

Ben, you're always shooting here and there
I feel you can shoot just about anywhere
If you ever look into space
And don't like the lens I placed upon your face
There's something you should do
Just shoot the image through :cool:

I've come to say:
"one point three"
that's the crop
the LCD is three
(Echo chorus: ) He's come to say:
"one point three"
that's the crop
the LCD is three

Ben, most people would just shoot away
They don't appreciate ISO-6400 anyway!
They just don't see you as I do
At 10-fps, I wish they would try to
I'm sure they'd think again
If they had a rig like 'Ben'
Like 'Ben'
Like 'Ben'
:eek:

Sorry SeeDubya, you left me little choice. Congrats on the new rig and I hope you two find the "sweet spot" together.

Congrats Christian! I'm sure both Ben's will make you proud. ;)

Hey, I missed your move from Shitney to Crapville!

Was the 1D mkIII you shot the race with a loaner?

Mmm new toys are the best. . . Any concerns re: the AF tracking systems hiccups that Rob Galbraith reported with both his preproduction and production model MKIIIs? reported here in this story. (http://www.robgalbraith.com/bins/content_page.asp?cid=7-8740-9006)

Ok OK you are right, I'm just trying to spoil the party! J/K - congrats on the new D. . .

Yeah, just a loaner - these are pretty much the first retail shipments in Aus. I ordered two - all I got was one for now. :(

No nothing like that yet. A lot of these were with the loan Mark III I had on the weekend (all ISO 3200):http://www.aflphotos.com.au/search/results/?q=collection:AFL%20Round%2012%20-%20Sydney%20v%20Collingwood

Focus didn't skip a beat. Measurably faster and more accurate IMO. Lens was the 400/2.8 IS and 1.4x II combo.

Thats interesting to know. . . I kinda wondered after reading that Galbraith article what, if any, if the focus issues were just a result of normal operations. What I mean is that the camera is suppose to sense movement and react but I figure that there are going to be delays in its processing - especially when the subject is moving directly towards the camera - I figure thats probably the hardest way to track a subject but then again, I guess I wouldn't know.

I read the Galbraith article too, and the naturescape stuff - some pretty experienced guys so maybe there's a few lemons out there, or maybe the conditions they shoot under happen to be the III's achilles heal.

I still get some frames in a sequence that are OOF now and then - but it's less than with the N.

All I know is that for the stuff I shoot (so far) the camera is a definite improvement. Even my 24-70/2.8 (a problem lens at times on the N) is working flawlessly at the moment.

Hmm, I am a quite techincal software developer, so my thinking about algorithms may be a bit different from you.

But as far as I can get my head around things now, a camera does not look at subjects, all the AF sensors do it note differences in contrast from sample to sample.
The camera software may make a lot of good or false conclusions about what the different AF sensors report, but those readings are the only thing it has to go on.

My guess is that a moving subject that goes directly towards or from you is the easiest to detect and to track. Suppose the camera has determined the subject (a ball) is at the central AF sensor, and in focus. The sensors to the left and right will "see" the subject (or just, that pasrt of the image) to be out of focus. Suppose the camera does not know what went on before we had focus lock, because then we dont have to take that into consideration in thsi example.
So... all it knows is: central sensor in focus. To the left, not in focus. To the right, not in focus.

What happens if the ball moves towards us...
The central sensor will find the scene to be less in focus.
The left and right sensor will see the scene MORE in focus. Conclusion? The ball has moved towards us.
If the ball had moved away, the central sensor would have seen the same, less contrast/focus. The left and right sensor would have seen even less focus, though. That would mean" ball moves away from us.

Just a very simplified view of how a camera can reach conclusions about tracking objects... and only with 3 sensors. The 1D MK III has over 40?

If the tracking problem is really a problem, it is a problem of the software which interprets the sensor readings. And that can be updated in future with a firmware update.

What do you think ... a doppler-effect using light?

kudos to that last reply.....
..... if only I had the skills to take such a camera to it's limits.Congrats on the buzz factor.;)

I've named it Ben - after my third Son. :)

ahh thats why the naming system was BEN_ when i used it :) was wondering why :)
