MK III Saga

[oeyvind]

In case, you guys have not read the latest update at Rob Galbraith's DPI on the MK III...

http://www.robgalbraith.com/bins/mul...740-9068-10086

They basically summarized it as...

Quote: In short, there's nothing in the over 4000 frames we've shot leading up to this article update to suggest that the revised AF calibration or v1.2.5 firmware have improved the camera's principal remaining autofocus weakness. If you shoot sports, or something equivalent to it, and therefore require strong autofocus tracking, the EOS-1D Mark III will continue to disappoint. It can capture some in-focus tracking sports pictures at wide open apertures, but it continues to flub the focus on more frames than it should for this level of camera. And it's still outclassed by its predecessor, the EOS-1D Mark II N (and the EOS-1D Mark II before that).

Ops, looks like this cam is a lemon after alll

The strange thing is I tried very hard to repeat what he mention in the reviews but can't. After the latest AF fixed...it is even harder to repeat what he mention. So is his camera an isolated case?

No. You should see what some so called fixed MkIIIs can do even with slow moving subjects. I have experienced it myself and with fast moving subjects as well. I dare say that in retrospect, the AF from lower-end cameras like the 20D onwards are far more reliable than the Mk III's.

You seem very determined to prove that (yours, in particular) Mk IIIs are perfect, and that a very respected consultant's view is an isloated case. I wonder why.

I wonder how many copies of the MK3 has he tried? I have shot side by side with another friend's 50D for BIF....same lens 70-200...I easily get 9/10 Sharp, while the 50D has about 6/10. Both in AI-Servo. On another shot with a friend who has the 1DM2.....has about the same result about 9/10 sharp copies.

Well you might say it could be a user issue....that I am not sure. I should have used his 50D to test that day too. Might ask him to go bird park again.

As for Rob being a very reputable consultant.....I will reserve my comments on that. How partial is he remains a question to me.

The cam seemed worse after the lastest calibration by the svc ctr and f/w 1.2.5
I can even get OOF shots with stationary objects..

I suspect that is Human (CSC technician) error more then a system error.

Okay how I calibrate my system....during the AF fixed....I sent in all my lenses together with the body and get CSC to calibrate all my lenses to the body....after that.....almost perfect. Even more perfect with primes.

I have 2 friends with 1DM3....I was the first to send in full system (1 body plus 6-7 lenses) to "AF fixed". Then the other 2 followed and did the same. Both have no issue with AF after that. All this are done FOC.

(Actually, I didn't experience much of a AF issue to begin with. Cos I bought the cam 1.5 years after launch....may be that might be the reason.)

Not to say that the mkIII is no good but the mkIII could be giving more in focus shots because it's easier to track a moving object with 45 AF points as compared to 9. In this case it is not because of the superior AF of the mkIII that is giving you more keepers but rather the inadequacy of the user that is causing so many OOF shots with the 20d etc. I used my friends mkII with my 40d side by side and I do notice that when you can keep your centre AF point on the object (shooting cars), the 40d actually gives more in focus shots than the mkII.
