Oh great - here we go again...

Well, he did uncover the MKIII issues so all we can do is wait and see what the masses think about the AF.

Yeah, but Nick, there's already a ton of evidence out there that the Mk IV's AF is the dog's bollocks for sport.

Besides, I recall his opinion of the 40D's AF - and he was just plain wrong about that.

So, anyone agree with him?

I was wondering when this would come out. I have a friend with a son on the Paradise Valley HS (PV) track team and he was there when RG was doing this round of tests.

Interesting read.

As a very happy MkIII owner with a 90%+ keeper rate, this is what I think.

What was his opinion of the 40D's af? To be honest Im not impressed with it.

Honestly, I don't think you can write off RG as just a Nikon fanboy. He gets detailed in his review, and if the 1D4 is off on the shots that he states, then that's a big issue. The issue with the 1D Mark III is no longer about Auto-focus, it's about trust. I really hope that he's wrong, but he shot multiple rounds of the same thing and got consistent results. Can't really be chalked up to "user error" as he knows what he's doing.

Definitely not a good review.

Yes, but even after the final fix for the MKIII, he did not retract his review. In fact I think he commented that even after the fix, nothing much changed.

I'm sure there are more than a few MKIII users that would beg to differ.

So I wouldn't dismiss him, but given his Nikon alliance, I would take it with a big grain of salt this time around.

Very good point Nick. The main part that worried me was the speed skating review. I'm shooting more and more kids hockey in poorly lit rinks. I've been considering the 1D4 to get that extra stop, but if it doesn't like behaving around ice, that would concern me.

I'd love to hear some more reviews of the 1D4's AF, especially around ice. Enquiring minds want to know!

I will also say that the 1D3's AF system is awesome. I'm amazed at my keeper rate.

The problem with this is that for the majority of of users and the majority of bodies, the MkIII has no issues and never did but it was tainted by RG and people saw problems when none existed. There were a few dodgy ones as with everything but it was and is nowhere near the failure that it's claimed to be based on RG's review.

The problem with this current review is that the MkIV really is not as good as the D3 for AF tracking. It's sad but true. However that's like saying a Lamborghini isn't as good as a Ferrari because it's slightly slower to 200mph. Both cameras are more than capable of doing the job and if you can't get the shot you want with a hit rate above 80%, which even a 40D can manage then it really is user error.
