I agree with you that using cut and paste in this case is indeed lying. And the way they tried to brush away the skeptism and critism by their readers makes it even worse. If I were the publisher I'd fire those who were involved in this.

I'm not defending PopPhoto in any way, and I'll sure would like to see numbers from a fresh AF test with the K20D, but I think many people over here are overreacting on this. I think you didn't quite get the explanation:
Let's say that the measured AF speeds for the K10D were 0.41, 0.45 and 0.48 for given light levels. Then they go out and measure the speeds for the K20D, coming out at 0.40, 0.46 and 0.47. How can you verify that these are real differences and not sample variation? You can't, unless you redo all the tests including the K10D. That's what I think they meant with "avoiding confusion".
What I think is really unfair is that SDM performance is untested. They should give it a go just for comparison. There is no updated 50mm with SDM in the foreseeable future, as it was dropped in favour of 55mm.
