Given your stance why would I think you were joking?


O.K. I stand corrected. I should have put a smiley.

You're assuming
A) RG doesn't have a contractual agreement (verbal/written) with Nikon
B) RG would accept Canon ad's in the first place


Exactly, just as you assume otherwise.

Happy shooting,
Yakim.

That is exactly the problem here - whether true or not, it appears that RG has been bought by Nikon. It's his largest contributor. He should either kick Nikon off his site, or recuse himself from testing competitors' products. The conflict of interest is huge.

Not to mention that there are a large number of satisfied professionals out there already that are speaking highly of the camera and particularly its autofocus system. So, his findings stand weak against the plethora of evidence stating otherwise.

He's not damaging Canon so much as he's damaging his own reputation by the appearance of impropriety. He

I agree entirely with this sentence. The difference between me and most other posters in this thread is that I refuse to declare he is "guilty" as long as this matter is not backed up by evidence. Call me naive if you want but I see myself simply as one who remembers the past.

I wonder what will you say if - in a few months time - Canon will issue a hardware fix to improve AF. The start of this saga is exactly like the start of the saga of the 1D3, and we all know how that ended. We only have to wait and see how this saga will progress.

Happy shooting,
Yakim.

Huge damage? Is that why I'm seeing 2 to 3 posts a day from people that want to buy a MKIV and can't?


Well, maybe not that huge but you may want to read the SS thread posted in the previous page.

Happy shooting,
Yakim.

Are you trying to say if it doesn't work for RG than automatically it should not for anybody else?


No. Please re-read my posts in this thread. All I'm saying is that this story (well, it is not yet a saga....) starts just like the previous one and I just can't believe how many people are not even considering the possibility that it might follow the same path.

Happy shooting,

It's not a lack of critical thinking, it's in most cases an awareness that something isn't right with this "review".

I am not in the market for this camera, nor do I plan to buy one any time soon. My interest is solely in Canon's engineering development, quality control, and integrity; three areas where they've proven themselves lacking in recent years.

I've always supported RG and never believed he demonstrated any bias, even after he switched to Nikon. If he actually has uncovered another substandard Canon product being sold as a professional tool, I, and anyone that thinks,should congratulate him.
...Show more

He addresses point 1 and 3 in the first page:

"The plan was to roll those comparison sequences into this article, along with an overview of Nikon autofocus and some general conclusions about how the AF systems compare. It became necessary to modify that plan when Canon released firmware v1.0.6 for the EOS-1D Mark IV, an update whose only stated change was to AI Servo tracking. This meant having to redo much of the shooting we'd already done with the EOS-1D Mark IV, which in turn meant it was then impossible to meet our deadline for this story, ahead of a period of heavy travel, and include all of what we had wanted to about Nikon.

That will come in another story to follow, a bit later in the first half of this year.
"

And I missed out point #4. Where does he said that?

Happy shooting,
Yakim.

I read this and like many others began to panic a bit about my purchase of the MKIV which will be delivered today but then after a day I settled down and remembered some of the very positive posts here about the MKIV and others reviews about the camera. So what RG says about the camera is his opinion and it was right on for the MKIII but I'll form my own opinion of this body when I get it and start using it. I remember shooting the MKIII in bright light and it felt sluggish while shooting so hopefully no more of that.

I never noticed all the Nikon ads on his site so that makes me think he has a little bias towards Canon and maybe his opinion isn't as honest as it should be.

One of the funny things about all this (funny in the weird/strange/sad/ironic sense) is that a major, enduring, critique of the RG MkIII review was that he didn't compare it the Nikon flagship. I was always kind of non-plussed by this argument, partly because I'm not really interested in Nikon. But also because it seemed like people were saying "Yes, I'll admit there are probably some issues with the MkIII's AF but I could stomach the criticism if it were compared to the Nikon pro body" (obviously assuming that Canon would carry the day in such a matchup.) Well,

You're right. I completely forgot about that.

So for the many RG faithful Canon has indeed Lost their Autofocus Mojo, without question.
No other 1D Mark IV review or reviewer matters.

Thanks for the heads-up o the thread in SS.

I just visited the site and opinion is divided; most certainly NOT what you claim above. In fact, I will say there are more doubters than believers of RG from that SS thread.

I think a comparison with the competition is very much interesting, particularily to those who think the sky has just fallen and they cry they are going to switch brands. You'd want to know if the camera you're switching to is actually better, otherwise you might be in for a disappointing and expensive surprise. Not that most switchers would ever admit something was wrong, either with their new camera or with the old one that is now on the B&S forum and suddenly flawless...

Let me say that I have no interest in this camera and usually don't do any focus tracking. I do read RG's pieces on different cameras though and what comes to mind is that he always previews/reviews Canon gear with a negative tone, punctuated with little nice things here and there while he's always infatuated by Nikon gear and dismisses their shortcomings as something small and irrelevant.

That's my personal feeling. Why he does it this way, I neither know nor care.

Yakim, I don't think anybody has denied the possibility that RG might be right: this - as I think has been made very clear already - is about the way he has presented his findings, which implicitly favours the D3S and damns the MK IV without there being anything of evidential substance to support this unfavourable comparison. Much of what appears in the review is "damning with faint praise" and innuendo.

We're to accept that the D3S is better on his say-so, even though there's some pretty compelling evidence that he had the Mk IV set up wrongly.

He presents his conclusion about the Mk IV (and about Canon's abililty to provide cameras with great AF) half way down the first page.

Many of his Mk IV images beg questions about how he has used the camera (his choice of AF point very rarely being on atheletes' faces - yes I know it can be hard to do this, but he's a "respected professional sports photographer", isn't he? Maybe the colleague wielding the D3s was better at that?)

Using an old firmware and then, in the "small print", acknowledging that he''s going to have to do the test again in the future, with all the implications that carries for the value of the current test...

Whether he's biased or not, whether he's in Nikon's pocket or not, this review can very easily be read as if both of these are true, which means that it is perfectly reasonable to have these doubts.

I see that he favours the D3S but I do not see that he damns the MK IV. He points pros and cons of both cameras? Yes. He says that he thinks the D3S is better? Yes. Well, I see nothing wrong with that.

Happy shooting,
Yakim.

yesterday I studied the skating files of RG.
with that results, I really wonder, why he uses the surrounding AF point III-8.2
I'm pretty sure that, with only the centre point active, CIII-8.0, the results are much better.
Why didn't he do that?

With RG's report would you switch to the D3S or buy the 1D4?

Really? For me path was - I got mk III in mid 2008 and successfully and used until Feb 2010 without any single issue. Now I would like to follow same path with mk IV ...

I wouldn't choose camera based on any single report.

There are also many aspects of the camera, the camera system, your needs, your budget etc that comes into choosing what to buy.

Precisely, and if you remember the 1D3 testing, the athlete running towards the camera had no logo on the shirt at all. So the AF could be easily confused. Yet again, this is a newbie mistake by this "respected pro photographer" who should know better.

I'd say there are far more doubters of RG's 1D Mark IV review here at fredmiranda than at sportsshooter.

Me?

I'm impressed with the 1D Mark IV images people are posting here. Seems there are alot of happy 1D Mark IV owners with images inhand.
