The AF perforamnce macthed that of 7D according to IR. How do you know that 7D did better than A55 when IR, who tested it, said otherwise?

We already know the 7D can do fine, enough people use it for sports and therefor enough information is available about that specific camera.





So since DPR hasn't posted any proof for whatever you claim they said, we don't have any reaon to doubt it and must accept it (since there are no crops). Nice logic.

It is not what I "claim" dpreview says, I am very sure YOU have read it there yourself too. Yet, for unknown reasons, you choose to disregard it.



Now, about IR, we KNOW the crops show nothing successful. And we KNOW, that while they say they did a comparison, they do not show the comparison, which really is quite odd (first time ever I have seen that on internet, actually). We also can see that they claim silly stuff (one shot out of a sequence within one second "camera shaken". And that under conditions you can't even imagine camera shake. And a test that is not really all that taxing.



So, it is clear what my objections are about the so called "test" of the AF tracking by IR. They are logical and I have explained them very clearly. Can you now stop arguing about it?



What your reason is to dismiss dpreview's assessment is not clear. They gave no specific details, so one can not fault their methodology, for instance. We can also not say it does not follow the trend, as we have no sources that seriously test the AF tracking performance of that camera's AF module.



We can however match it with statements of people who actually have used both (like Yakim).



Like I said, I will try to make a 1 second sequence with my camera and 70-200mm lens, mimicking as close as possible what IR describes. Then we will have something to compare the IR results with.
