I don't care he's pro-Pentax at the moment. I don't trust he's doing a thorough job in his tests and comparisons.
OTOH, the D FA 150-450 is an excellent lens.
I think he does great job ......... his choice of subjects such as the pylons against a bright cloudy sky shows up the weaknesses of sharpness/ contrast of the Fuji etc.. all too easy to think because he's not shooting (boring) brick walls or test charts that his method is flawed ..... apart from the silly bear ..... and there's no doubt his on Pentax's side.
The D FA 150-450mm is a great lens ...... however, it didn't take him long to show that the 70-200mm F2.8 is a focus breather ...... he's smart!!

The glass might not be the same (I don't quite believe this, but the Pentax version is said to have 2 anomalous dispersion elements).
The coatings might not be the same, the Pentax version is said to have HD and SP. Let's see if we can verify this.
The mechanics are not the same, the Pentax version has a focus limiter.
The inner barrel is not the same, there's at least one anti-reflexion baffle missing from the Tamron.
And the Pentax D FA* 70-200 f/2.8 is optically superior.
That sounds like DPreview forum talk to me ....
I think Pentax meant "anonymous elements"
Tamron sell a removable tripod foot for the lens at 120 euros ..... there's not one supplied ........
